text: "The dynamics of charge and spin injection currents excited by circularly
polarized, one-color laser beams in\r\nsemiconductor quantum wells is analyzed.
Our microscopic approach is based on a 14x14 k · p band-structure\r\ntheory in
combination with multisubband semiconductor Bloch equations which allows a detailed
analysis of\r\nthe photogenerated carrier distributions and coherences in k space.
Charge and spin injection currents are\r\nnumerically calculated for [110]- and
[001]-grown GaAs quantum wells including dc population contributions\r\nand ac
contributions that arise from intersubband coherences. The dependencies of the
injection currents on the\r\nexcitation conditions, in particular, the photon
energy are computed and discussed."

text: We report the development of an experimental technique to measure the dynamics
of electrical currents on the femtosecond timescale. The technique combines methods
of coherent control with time- and angle-resolved photoelectron spectroscopy.
Direct snapshots of the momentum distribution of the excited electrons as function
of time are then determined by photoelectron spectroscopy. In this way we gain
information on the generation and decay of ultrashort current pulses in unprecedented
detail. In particular, this technique allows the observation of elastic electron
scattering in terms of an incoherent population dynamics in momentum space. We
have applied this optical current generation and detection scheme to electrons
in so-called image-potential states which represent a prototype of two-dimensional
electronic surface states. Electrons in these states are bound perpendicular to
the metal surface by the Coulombic image potential whereas they can move almost
freely parallel to the surface. For the (n=1) image-potential state of Cu(100)
we find a decay time of 10 fs due to electron scattering with steps and surface
defects.

text: A microscopic theory that describes injection currents in GaAs quantum wells
is presented. 14 × 14 band k.p theory is used to compute the band structure including
anisotropy and spin-orbit interaction. Transient injection currents are obtained
via numerical solutions of the semiconductor Bloch equations. Depending on the
growth direction of the considered quantum well system and the propagation and
polarization directions of the incident light beam, it is possible to generate
charge and/or spin photocurrents on ultrashort time scales. The dependence of
the photocurrents on the excitation conditions is computed and discussed.

text: We present an analysis of the coupling between photonic crystal cavities in
different geometries. Inline‐, side‐ and angle‐coupled L3‐geometries are investigated
numerically in three dimensions. Asymmetric mode splitting of the fundamental
mode for the L3‐cavity is shown for all geometrical setups evidencing for strong
cavity‐cavity interactions. The coupling efficiency for the fundamental mode is
shown to be best for a 30° angle between the cavity‐centers due to the direction
of in‐plane leackage out of the cavites.

text: We discuss transport and localization properties on the insulating side of
the disorder dominated superconductor-insulator transition, described in terms
of the dirty boson model. Analyzing the spectral properties of the interacting
bosons in the absence of phonons, we argue that the Bose glass phase admits three
distinct regimes. For strongest disorder the boson system is a fully localized,
perfect insulator at any temperature. At smaller disorder, only the low temperature
phase exhibits perfect insulation while delocalization takes place above a finite
temperature. We argue that a third phase must intervene between these perfect
insulators and the superconductor. This conducting Bose glass phase is characterized
by a mobility edge in the many body spectrum, located at finite energy above the
ground state. In this insulating regime purely electronically activated transport
occurs, with a conductivity following an Arrhenius law at asymptotically low temperatures,
while a tendency to superactivation is predicted at higher T. These predictions
are in good agreement with recent transport experiments in highly disordered films
of superconducting materials.

text: We discuss transport and localization properties on the insulating side of
the disorder dominated superconductor-insulator transition, described in terms
of the dirty boson model. Analyzing the spectral properties of the interacting
bosons in the absence of phonons, we argue that the Bose glass phase admits three
distinct regimes. For strongest disorder the boson system is a fully localized,
perfect insulator at any temperature. At smaller disorder, only the low temperature
phase exhibits perfect insulation while delocalization takes place above a finite
temperature. We argue that a third phase must intervene between these perfect
insulators and the superconductor. This conducting Bose glass phase is characterized
by a mobility edge in the many body spectrum, located at finite energy above the
ground state. In this insulating regime purely electronically activated transport
occurs, with a conductivity following an Arrhenius law at asymptotically low temperatures,
while a tendency to superactivation is predicted at higher T. These predictions
are in good agreement with recent transport experiments in highly disordered films
of superconducting materials.

text: We compute photocurrents generated by femtosecond single-color laser pulses
in non-centrosymmetric semiconductor quantum wells by combining a 14 x 14 k.p
band structure theory with multi-band semiconductor Bloch equations. The transient
photocurrents are investigated experimentally by measuring the associated Terahertz
emission. The dependencies of the photocurrent and the Terahertz emission on the
excitation conditions are discussed for (110)-oriented GaAs quantum wells. The
comparison between theory and experiment shows a good agreement.

text: Semiconductor nanostructures always contain a certain degree of disorder due
to interface roughness and/or alloy disorder. The disorder has significant influence
on the optical properties, e.g., excitonic absorption spectra. An adaptive wavelet
approach for the solution of the excitonic Schroedinger equation, i.e., the semiconductor
Bloch equation for the interband coherence linear in the external field, has been
developed and applied to compute absorption spectra and/or wave functions. Results
obtained for a thin GaAs semiconductor quantum wire considering a number of different
model disorder potentials are presented and discussed.

text: The behavior of waveguide plasmon polaritons is studied employing ultrafast
coherent control like schemes for a gold lattice coupled to a photonic waveguide
for the structure. Different models to describe the third-harmonic generation
are presented and the resulting equations are solved numerically. The calculations
are compared to recent experimental data and show good agreement for the most
prominent features in the time-integrated third order intensity.

AlAs bulk and heterostructures. Thereby, we compare the theoretical description
of optical excitation on several levels of theory. Results obtained from kp theory
are discussed along with data from ab initio calculations within the frameworks
of independent-particle (DFT), independent quasiparticle (GW), or Coulomb-correlated
quasiparticle (BSE) approximation.

text: "Excitonic spectra of weakly disordered semiconductor heterostructures are
simulated on the basis of a\r\none-dimensional tight-binding model. The influence
of the length scale of weak disorder in quantum wells on\r\nthe redshift of the
excitonic peak and its linewidth is studied. By calculating two-dimensional Fouriertransform\r\nspectra
we are able to determine the contribution of disorder to inhomogeneous and also
to homogeneous\r\nbroadenings separately. This disorder-induced dephasing is related
to a Fano-type coupling and leads\r\nto contributions to the homogeneous linewidth
that depends on energy within the inhomogeneously broadened\r\nline. The model
includes heavy- and light-hole excitons and yields smaller inhomogeneous broadening
for the\r\nlight-hole exciton if compared to the heavy-hole exciton, which agrees
qualitatively with the experiment."

text: We numerically investigate the behavior of Whispering Gallery Modes (WGMs)
in circularly shaped resonators like microdisks, with diameters in the range of
optical vacuum wavelengths. The microdisk is embedded in an uniaxial anisotropic
dielectric environment. By changing the optical anisotropy, one obtains spectral
tunability of the optical modes. The degree of tunability strongly depends on
the radial (azimuthal) mode order M (N). As the modes approach each other spectrally,
anticrossing is observed, leading to a rearrangement of the optical states.

text: The coherent state manipulation of single quantum systems is a fundamental
requirement for the implementation of quantum information processors. Exciton
qubits are of particular interest for coherent optoelectronic applications, in
particular due to their excellent coupling to photons. Until now, coherent manipulations
of exciton qubits in semiconductor quantum dots have been performed predominantly
by pulsed laser fields. Coherent control of the population of excitonic states
with a single laser pulse, observed by Rabi oscillations, has been demonstrated
by several groups using different techniques1,2,3. By using two laser pulses,
more general state control can be achieved4, and coupling of two excitons has
been reported5,6. Here, we present a conceptually new approach for implementing
the coherent control of an exciton two-level system (qubit) by means of a time-dependent
electric interaction. The new scheme makes use of an optical clock signal and
a synchronous electric gate signal, which controls the coherent manipulation.

text: GaAs-based semiconductor microdisks with high quality whispering gallery modes
(Q44000) have been fabricated.A layer of self-organized InAs quantumdots (QDs)
served as a light source to feed the optical modes at room temperature. In order
to achieve frequency tuning of the optical modes, the microdisk devices have been
immersed in 4 – cyano – 4´-pentylbiphenyl (5CB), a liquid crystal(LC) with a nematic
phase below the clearing temperature of TC≈34°C .We have studied the device performance
in the temperature rangeof T=20-50°C, in order to investigate the influence of
the nematic–isotropic phase transition on the optical modes. Moreover,we havea
pplied an AC electric field to the device,which leads in the nematic phase to
a reorientation of the anisotropic dielectric tensor of the liquid crystal.This
electrical anisotropy can be used to achieve electrical tunability of the optical
modes.Using the finite-difference time domain (FDTD) technique with an anisotropic
material model, we are able to describe the influence of the liquid crystal qualitatively.

text: "It is demonstrated that valence-band mixing in GaAs quantum wells tremendously
modifies electronic\r\ntransport. A coherent control scheme in which ultrafast
currents are optically injected into undoped GaAs\r\nquantum wells upon excitation
with femtosecond laser pulses is employed. An oscillatory dependence of\r\nthe
injection current amplitude and direction on the excitation photon energy is observed.
A microscopic\r\ntheoretical analysis shows that this current reversal is caused
by the coupling of the light- and heavy-hole\r\nbands and that the hole currents
dominate the overall current response. These surprising consequences of\r\nband
mixing illuminate fundamental physics as they are unique for experiments which
are able to monitor\r\nelectronic transport resulting from carriers with relatively
large momenta."

necessary. One of the fundamental works concerning field singularities has been
proposed in 1972 [1] and states that the electromagnetic energy density must be
integrable over any finite\r\ndomain, even if this domain contains singularities.
It is shown, that the magnetic field \x02H(\x03, ϕ) and electric field \x02E(\x03,
ϕ) are proportional to ∝ \x03(t−1) for \x03 → 0. The variable \x03 is the distance
to the edge and t has to fulfill the integrability condition and thus is restricted
to 0 < t < 1. This result is often used to reduce the error corresponding to the
singularity without increasing the numerical effort [2 - 5]. For this purpose,
a correction factor K is estimated by inserting the proportionality into the wave
equation. It is shown, that this method improves the accuracy of the result significantly,
however the order of convergence is often not studied. In [4] a method to modify
the material parameters in order to use analytic results to improve the numeric
calculation is presented. In this contribution we will - inspired by the scheme
given in [4] - develop a new method to estimate a correction factor for perfect
conducting materials (PEC) and demonstrate the improvement of the results compared
to the standard edge correction. Therefore analytic results (comparable to [1])
are consequently merged with the scheme in [4]. The main goal of this work is
the calculation of the second harmonic generation (SHG) in the wave response of
so-called metamaterials [6]. Frequently these structures\r\ncontain sharp metallic
edges with field singularities at the interfaces which have a strong impact on
the SHG signals. Thus, an accurate simulation of singularities is highly important.
However, the following approach can also be applied to many other setups, and
one of them is shown in the example below."

text: "Microdisks made from GaAs with embedded InAs quantum dots are immersed in
the liquid crystal 4-cyano-4’-pentylbiphenyl (5CB). The quantum dots serve as
emitters feeding the optical modes of the photonic cavity. By changing temperature,
the liquid crystal undergoes a phase transition from the isotropic to the nematic
state, which can be used\r\nas an effective tuning mechanism of the photonic modes
of the cavity. In the nematic state, the uniaxial electrical anisotropy of the
liquid crystal molecules can be exploited for orienting the material in an electric
field,\r\nthus externally controlling the birefringence of the material. Using
this effect, an electric field induced tuning of the modes is achieved. Numerical
simulations using the finite-differences time-domain (FDTD) technique\r\nemploying
an anisotropic dielectric medium allow to understand the alignment of the liquid
crystal molecules on the surface of the microdisk resonator."

text: We demonstrate a technique for the generation and detection of electron currents
at surfaces on a femtosecond time scale with a contact-free experimental setup
based on a combination of coherent control and photoemission spectroscopy. We
have applied this technique for electrons excited into image-potential states
on a Cu(100) surface that form a free-electron-like band in the direction parallel
to the surface. The photogeneration of currents is described by optical Bloch
equations for a multiband model. By incorporating field-induced interband and
intersubband transitions together with intraband accelerations into the model,
the observed phase dependence of the population and of the current can be reproduced.
