text: A unified theoretical approach to describe the properties of multimode
squeezed light generated in a lossy medium is presented. This approach is valid
for Markovian environments and includes both a model of discrete losses based
on the beamsplitter approach and a generalized continuous loss model based on
the spatial Langevin equation. For an important class of Gaussian states, we derive
master equations for the second-order correlation functions and illustrate their
solution for both frequency-independent and frequency-dependent losses. Studying
the mode structure, we demonstrate that in a lossy environment no broadband basis
without quadrature correlations between the different broadband modes exists.
Therefore, various techniques and strategies to introduce broadband modes can
be considered. We show that the Mercer expansion and the Williamson-Euler decomposition
do not provide modes in which the maximal squeezing contained in the system can
be measured. In turn, we find a new broadband basis that maximizes squeezing in
the lossy system and present an algorithm to construct it.

text: We investigate the dynamics of wave packets in a parabolic optical
lattice formed by combining an optical lattice with a global parabolic trap. Our
study examines the phase space representation of the system's eigenstates by comparing
them to the classical phase space of a pendulum, to which the system effectively
maps. The analysis reveals that quantum states can exhibit mixed dynamics by straddling
the separatrix. A key finding is that the dynamics around the separatrix enables
the controlled creation of highly nonclassical states, distinguishing them from
the classical oscillatory or rotational dynamics of the pendulum. By considering
a finite momentum of the initial wave packet, we demonstrate various dynamical
regimes. Furthermore, a slight energy mismatch between nearly degenerate states
localized at opposite turning points of the trap potential results in controlled
long-range dynamical tunneling. These results can be interpreted as quantum beating
between a clockwise rotating and a counterclockwise rotating pendulum.

text: In this paper, we theoretically study the spectral and temporal properties
of pulsed spontaneous parametric down-conversion (SPDC) generated in lossy waveguides.
Our theoretical approach is based on the formalism of Gaussian states and the
Langevin equation, which is elaborated for weak parametric down-conversion and
photon-number-unresolved click detection. Using the example of frequency-degenerate
type-II SPDC generated under the pump-idler group-velocity-matching condition,
we show how the joint-spectral intensity, mode structure, normalized second-order
correlation function, and Hong-Ou-Mandel interference pattern depend on internal
losses of the SPDC process. We found that the joint-spectral intensity is almost
insensitive to internal losses, while the second-order correlation function shows
a strong dependence on them, being different for the signal and idler beams in
the presence of internal losses. Based on the sensitivity of the normalized second-order
correlation function, we show how its measurement can be used to experimentally
determine internal losses.

text: We introduce a new classification of multimode states with a fixed number
of photons. This classification is based on the factorizability of homogeneous
multivariate polynomials and is invariant under unitary transformations. The classes
physically correspond to field excitations in terms of single and multiple photons,
each of which being in an arbitrary irreducible superposition of quantized modes.
We further show how the transitions between classes are rendered possible by photon
addition, photon subtraction, and photon-projection nonlinearities. We explicitly
put forward a design for a multilayer interferometer in which the states for different
classes can be generated with state-of-the-art experimental techniques. Limitations
of the proposed designs are analyzed using the introduced classification, providing
a benchmark for the robustness of certain states and classes.

text: 'Entangled two-mode Gaussian states constitute an important building
block for continuous variable quantum computing and communication protocols. In
this work, we theoretically study two-mode bipartite states, which are extracted
from multimode light generated via type-II parametric downconversion (PDC) in
lossy waveguides. For these states, we demonstrate that the squeezing quantifies
entanglement and we construct a measurement basis, which results in the maximal
bipartite entanglement. We illustrate our findings by numerically solving the
spatial master equation for PDC in a Markovian environment. The optimal measurement
modes are compared with two widely used broadband bases: the Mercer–Wolf basis
(the first-order coherence basis) and the Williamson–Euler basis.'

text: Tunneling ionization is a crucial process in the interaction between
strong laser fields and matter which initiates numerous nonlinear phenomena including
high-order harmonic generation, photoelectron holography, etc. Both adiabatic
and nonadiabatic tunneling ionization are well understood in atomic systems. However,
the tunneling dynamics in solids, especially nonadiabatic tunneling, has not yet
been fully understood. Here, we study the sub-cycle resolved strong-field tunneling
dynamics in solids via a complex saddle-point method. We compare the instantaneous
momentum at the moment of tunneling and the tunneling distances over a range of
Keldysh parameters. Our results demonstrate that for nonadiabatic tunneling, tunneling
ionization away from Γ point is possible. When this happens the electron has a
nonzero initial velocity when it emerges in the conduction band. Moreover, consistent
with atomic tunneling, a reduced tunneling distance as compared to the quasi-static
case is found. Our results provide remarkable insight into the basic physics governing
the sub-cycle electron tunneling dynamics with significant implications for understanding
subsequent strong-field nonlinear phenomena in solids.

text: "Abstract\r\n Experiments with
ultracold atoms in optical lattices usually involve a weak parabolic trapping
potential which merely serves to confine the atoms, but otherwise remains negligible.
In contrast, we suggest a different class of experiments in which the presence
of a stronger trap is an essential part of the set-up. Because the trap-modified
on-site energies exhibit a slowly varying level spacing, similar to that of an
anharmonic oscillator, an additional time-periodic trap modulation with judiciously
chosen parameters creates nonlinear resonances which enable efficient Floquet
engineering. We employ a Mathieu approximation for constructing the near-resonant
Floquet states in an accurate manner and demonstrate the emergence of effective
ground states from the resonant trap eigenstates. Moreover, we show that the population
of the Floquet states is strongly affected by the phase of a sudden turn-on of
the trap modulation, which leads to significantly modified and rich dynamics.
As a guideline for further studies, we argue that the deliberate population of
only the resonance-induced effective ground states will allow one to realize Floquet
condensates which follow classical periodic orbits, thus providing challenging
future perspectives for the investigation of the quantum–classical correspondence."

text: The prediction of photon echoes is an important technique for gaining an understanding
of optical quantum systems. However, this requires a large number of simulations
with varying parameters and/or input pulses, which renders numerical studies expensive.
This article investigates how we can use data-driven surrogate models based on
the Koopman operator to accelerate this process. In order to be successful, we
require a model that is accurate over a large number of time steps. To this end,
we employ a bilinear Koopman model using extended dynamic mode decomposition and
simulate the optical Bloch equations for an ensemble of inhomogeneously broadened
two-level systems. Such systems are well suited to describe the excitation of
excitonic resonances in semiconductor nanostructures, for example, ensembles of
semiconductor quantum dots. We perform a detailed study on the required number
of system simulations such that the resulting data-driven Koopman model is sufficiently
accurate for a wide range of parameter settings. We analyze the L2 error and the
relative error of the photon echo peak and investigate how the control positions
relate to the stabilization. After proper training, the dynamics of the quantum
ensemble can be predicted accurately and numerically very efficiently by our methods.
