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: 'Effective single-particle theories, such as Hartree–Fock, density functional
theory, and tight-binding, are limited by the computational cost of the self-consistent
field (SCF) procedure, which typically scales cubically with the system size.
This makes large-scale applications impractical without specialized algorithms
and hardware. Here, we present the submatrix and graphical processing unit (GPU)-accelerated
software implementation of the PTB tight-binding potential, realized in the open-source
ptb codebase [M. Mueller, A. Katbashev, and S. Ehlert (2025). “grimme-lab/ptb:
v3.8.1,” Zenodo. https://zenodo.org/records/17015872]. We first benchmark a traditional
diagonalization-based SCF solver against density-matrix-based purification approaches,
systematically varying both system size and computer hardware. Our findings show
that the usage of GPUs permits shifting the boundaries to much larger systems
than previously thought feasible, achieving an overall 10–15-fold performance
speedup. Second, we introduce the implementation of a decomposition-type submatrix
method, specifically designed for efficient operation on mid- to large-sized systems,
to address the computational overhead associated with full-system diagonalization.
We demonstrate that, from a certain dimension (≈104 basis functions) on, our submatrix
method reduces the overall computational cost while maintaining acceptable numerical
accuracy. Our study demonstrates the significance of the interplay between modern
hardware, algorithmic considerations, and novel tight-binding methods, paving
the way for further development in this direction.'

text: In the context of high-performance computing (HPC) for distributed workloads,
individual field-programmable gate arrays (FPGAs) need efficient ways to exchange
data, which requires network infrastructure and software abstractions. Dedicated
multi-FPGA clusters provide inter-FPGA networks for direct device to device communication.
The oneAPI high-level synthesis toolchain offers I/O pipes to allow user kernels
to interact with the networking ports of the FPGA board. In this work, we evaluate
using oneAPI I/O pipes for direct FPGA-to-FPGA communication by scaling a SYCL
implementation of a Jacobi solver on up to 25 FPGAs in the Noctua 2 cluster. We
see good results in weak and strong scaling experiments.

text: "We propose a spatio-spectral, combined model-based and data-driven\r\ndiarization
pipeline consisting of TDOA-based segmentation followed by\r\nembedding-based
clustering. The proposed system requires neither access to\r\nmulti-channel training
data nor prior knowledge about the number or placement\r\nof microphones. It works
for both a compact microphone array and distributed\r\nmicrophones, with minor
adjustments. Due to its superior handling of\r\noverlapping speech during segmentation,
the proposed pipeline significantly\r\noutperforms the single-channel pyannote
approach, both in a scenario with a\r\ncompact microphone array and in a setup
with distributed microphones.\r\nAdditionally, we show that, unlike fully spatial
diarization pipelines, the\r\nproposed system can correctly track speakers when
they change positions."

text: Exciton polariton condensates are macroscopic coherent states in which
topological excitations can be observed. In this work, we observe the excitation
of the vortices and realize tuning the topological charge by manipulating the
pumping configurations. Using a digital micromirror device, we constructed an
annular pumping pattern where the inner and outer rings can be easily tuned. Both
the number and the topological charge of the vortices can be changed by slightly
tuning the inner ring position against the outer ring. The experimental results
can be reproduced in theory by the Gross–Pitaevskii equation. Our work offers
to generate and manipulate vortices in exciton polariton condensates using a straightforward
optical method.

text: "Abstract\r\n Muonic hydrogen
is an exotic atom where a muon instead of an electron is bound to a proton. The
comparably high mass of the muon (≈ 207 · me\r\n
\ ) has two important effects, (i) the reduced mass
of the system becomes more important, and (ii) the muon is localized much closer
to the nucleus. Thus, muonic hydrogen is not only excellently suitable for evaluating
highly precise quantum electrodynamic (QED) calculations, but may also be used
for assessing new approaches including finite nuclear size (FNS) effects to evaluate
the proton structure and improve calculation schemes for the hyperfine splittings
of many-particle systems, as e.g. to be implemented in density functional theory
(DFT) software packages. Here, starting from Dirac’s equation we calculate the
relativistic hyperfine splitting of the ground state and several excited states
of muonic hydrogen analytically for different charge and magnetization models.
The FNS related hyperfine shifts are compared with the differences between QED
calculations and experimental measurements. This comparison also allows to unravel
the role of the reduced mass, which is on one hand crucial in case of muonic atoms,
but on the other hand is by no means well defined in relativistic quantum mechanics."

text: Non-Hermitian systems hosting exceptional points (EPs) exhibit enhanced sensitivity
and unconventional mode dynamics. Going beyond isolated EPs, here we report on
the existence of exceptional rings (ERs) in planar optical resonators with specific
form of circular dichroism and TE-TM splitting. Such exceptional rings possess
intriguing topologies as discussed earlier for condensed matter systems, but they
remain virtually unexplored in presence of nonlinearity, for which our photonic
platform is ideal. We find that when Kerr-type nonlinearity (or saturable gain)
is introduced, the linear ER splits into two concentric ERs, with the larger-radius
ring being a ring of third-order EPs. Transitioning from linear to nonlinear regime,
we present a rigorous analysis of spectral topology and report enhanced and adjustable
perturbation response in the nonlinear regime. Whereas certain features are specific
to our system, the results on non-Hermitian spectral topology and nonlinearity-enhanced
perturbation response are generic and equally relevant to a broad class of other
nonlinear non-Hermitian systems, providing a universal framework for engineering
ERs and EPs in nonlinear non-Hermitian systems.

text: "Abstract\r\n \r\n Negatively
charged boron vacancies () in hexagonal boron nitride (hBN) are emerging as promising
solid‐state spin qubits due to their optical accessibility, structural simplicity,
and compatibility with photonic platforms. However, quantifying the density of
such defects in thin hBN flakes has remained elusive, limiting progress in device
integration and reproducibility. Here, an all‐optical method is presented to quantify
\ defect density in hBN by correlating Raman and photoluminescence (PL) signatures
with irradiation fluence. Two defect‐induced Raman modes, D1 and D2, are identified
and assigned them to vibrational modes of using polarization‐resolved Raman measurements
and density functional theory (DFT) calculations. By adapting a numerical model
originally developed for graphene, an empirical relationship linking Raman (D1,\r\n
\ E\r\n 2g\r\n
\ ) and PL intensities is established to absolute defect densities.
This method is universally applicable across various irradiation types and uniquely
suited for thin flakes, where conventional techniques fail. The approach enables
accurate, direct, and non‐destructive quantification of spin defect densities
down to 10\r\n 15\r\n defects/cm\r\n
\ 3\r\n , offering a
powerful tool for optimizing and benchmarking hBN for quantum optical applications.\r\n

text: ABSTRACTSpin‐coated polylactide (PLA) thin
films were exposed to nitrogen plasma for varying time intervals. The progressive
etching of the PLA film in direct contact with the nitrogen plasma was monitored
in situ using polarization modulated infrared reflection absorption spectroscopy
(PM‐IRRAS). No appreciative changes in composition were seen with PM‐IRRAS, indicating
that the etching did not significantly affect the bulk composition. Atomic force
microscopy characterization of the plasma‐etched films showed that the PLA films
are homogeneously etched. Subsequent ex situ XPS analysis of the treated surface
revealed the presence of C‐N bonds in the surface‐near region that could be associated
with amino and/or amide surface species. PLA films were also alternatively exposed
to nitrogen ion beams produced by an electron‐cyclotron‐resonance (ECR) plasma
source and were investigated in vacuo by XPS. This treatment revealed the partial
substitution of surface oxygen species by nitrogen, resulting in a similar surface
modification as in the plasma case. The comparison of XPS data and water contact
angle studies suggest that the activated surfaces show a reorientation of macromolecular
fragments in the surface‐near region depending on the polarity of the phase with
which they are in contact. Under ultra‐high vacuum (UHV) conditions, the surface
tends to lower its surface energy, while in contact with the aqueous phase, subsurface
polar groups orientate outwards, which enables the formation of hydrogen bonds.
