text: "Abstract\r\n The phenomenon
of entanglement is the basis of quantum information and quantum communication
processes. Entangled systems with a large number of photons are of great interest
at present because they provide a platform for streaming technologies based on
photonics. In this paper we present a device which operates with four-photons
and based on the Hong–Ou–Mandel interference. The presented device allows to maximize
the degree of spatial entanglement and generate the highly entangled four-dimensional
Bell states. Furthermore, the use of the interferometer in different regimes leads
to fast interference fringes in the coincidence probability with period of oscillations
twice smaller than the pump wavelength. We have a good agreement between theoretical
simulations and experimental results."

text: The cubic, tetragonal, and orthorhombic phase of potassium niobate (KNbO3)
are studied based on density-functional theory. Starting from the relaxed atomic
geometries, we analyze the influence of self-energy corrections on the electronic
band structure within the GW approximation. We find that quasiparticle shifts
widen the direct (indirect) band gap by 1.21 (1.44), 1.58 (1.55), and 1.67 (1.64)
eV for the cubic, tetragonal, and orthorhombic phase, respectively. By solving
the Bethe-Salpeter equation, we obtain the linear dielectric function with excitonic
and local-field effects, which turn out to be essential for good agreement with
experimental data. From our results, we extract an exciton binding energy of 0.6,
0.5, and 0.5 eV for the cubic, tetragonal, and orthorhombic phase, respectively.
Furthermore, we investigate the nonlinear second-harmonic generation (SHG) both
theoretically and experimentally. The frequency-dependent second-order polarization
tensor of orthorhombic KNbO3 is measured for incoming photon energies between
1.2 and 1.6 eV. In addition, calculations within the independent-(quasi)particle
approximation are performed for the tetragonal and orthorhombic phase. The novel
experimental data are in excellent agreement with the quasiparticle calculations
and resolve persistent discrepancies between earlier experimental measurements
and ab initio results reported in the literature.

text: 'The KTiOPO4 (KTP) band structure and dielectric function are calculated on
various levels of theory starting from density-functional calculations. Within
the independent-particle approximation an electronic transport gap of 2.97 eV
is obtained that widens to about 5.23 eV when quasiparticle effects are included
using the GW approximation. The optical response is shown to be strongly anisotropic
due to (i) the slight asymmetry of the TiO6 octahedra in the (001) plane and (ii)
their anisotropic distribution along the [001] and [100] directions. In addition,
excitonic effects are very important: The solution of the Bethe–Salpeter equation
indicates exciton binding energies of the order of 1.5 eV. Calculations that include
both quasiparticle and excitonic effects are in good agreement with the measured
reflectivity.'

text: The fundamental interband absorption in gallium arsenide shows a strong blue
shift when biased by mid-infrared transients exceeding 10 MV/cm. This subcycle
feature is induced by the localization of electronic wavefunctions from 3D to
2D.

text: "Measurement-induced nonclassical effects in a two-mode interferometer are\r\ninvestigated
theoretically using numerical simulations and analytical results.\r\nWe demonstrate
that for certain parameters measurements within the\r\ninterferometer lead to
the occurrence of two-mode squeezing. The results\r\nstrongly depend on the detection
probability, the phase inside the\r\ninterferometer, and the choice of the input
states. The appropriate parameters\r\nfor maximized squeezing are obtained. We
analyze the influence of losses and\r\nconfirm that the predicted effects are
within reach of current experimental\r\ntechniques."

text: "Spontaneous formation of transverse patterns is ubiquitous in nonlinear\r\ndynamical
systems of all kinds. An aspect of particular interest is the active\r\ncontrol
of such patterns. In nonlinear optical systems this can be used for\r\nall-optical
switching with transistor-like performance, for example realized\r\nwith polaritons
in a planar quantum-well semiconductor microcavity. Here we\r\nfocus on a specific
configuration which takes advantage of the intricate\r\npolarization dependencies
in the interacting optically driven polariton system.\r\nBesides detailed numerical
simulations of the coupled light-field exciton\r\ndynamics, in the present paper
we focus on the derivation of a simplified\r\npopulation competition model giving
detailed insight into the underlying\r\nmechanisms from a nonlinear dynamical
systems perspective. We show that such a\r\nmodel takes the form of a generalized
Lotka-Volterra system for two competing\r\npopulations explicitly including a
source term that enables external control.\r\nWe present a comprehensive analysis
both of the existence and stability of\r\nstationary states in the parameter space
spanned by spatial anisotropy and\r\nexternal control strength. We also construct
phase boundaries in non-trivial\r\nregions and characterize emerging bifurcations.
The population competition\r\nmodel reproduces all key features of the switching
observed in full numerical\r\nsimulations of the rather complex semiconductor
system and at the same time is\r\nsimple enough for a fully analytical understanding
of the system dynamics."
