Ultraviolet Raman spectroscopy using multimode aluminum oxide waveguides
Waveguide-based Raman spectroscopy offers a route toward compact and integrated photonic sensors.Quantum Popcorn: the shape of a phase transition bubble
A quantum tunneling event in field theory is usually depicted as the materialization of a spherical bubble of true vacuum.eCAS: An Orbital Embedding Method for Quantum Computing
Future fault-tolerant quantum computers will allow us to calculate electronic structures of atomistic systems.Dark Halos, Intermediate-Mass BH and Nuclear Stellar Clusters in Dwarf Spheroidals
We exploit the halo densities of three dwarf spheroidals recently obtained to investigate their dark matter distribution.A Hybrid Message-Passing and Electric-Field Representation for Electrostatic QM/MM Embedding with Machine Learning Interatomic Potentials
Within a hybrid quantum mechanics/molecular mechanics approach a small region of a large atomistic system is described quantum mechanically, while the rest of the system is represented by a…High-efficiency photonic GHZ measurements with linear optics
Probabilistic and destructive Bell-measurements, also known as fusions, constitute a fundamental primitive for photonic quantum technologies.FaultScope: A software package for fast error attribution in quantum error correction
We introduce FaultScope, a classical simulator for quantum error correction circuits, implemented in Rust with a Python interface.The Generalized Twin Image: Understanding Regularized Phase Retrieval
Image priors can dramatically improve phase retrieval reconstruction, but their effectiveness strongly varies between imaging modalities.Symmetries and model reduction in a $\cos 2\varphi$ transmon qubit
Engineered symmetries in superconducting circuits can protect quantum information; much like selection rules in atomic physics, they forbid transitions between the qubit states.AMPERe: an exactly divergence-free quadrature-by-expansion evaluator for near-surface Biot--Savart and virtual-casing fields in fusion geometries
Accurate magnetic-field evaluation on and near current-carrying surfaces is a recurring computational bottleneck in magnetic-confinement fusion.The JWST/PASSAGE Survey: Metallicity Radial Gradients in Emission-Line Galaxy Pairs at Cosmic Noon with NIRISS
Using JWST/NIRISS slitless spectroscopy from the PASSAGE program, we analyze 17 spectroscopically confirmed emission-line galaxies in candidate interacting systems at $z \sim 1.7$--$3.2$.Co-evolution of AGN and Host Galaxies across Cosmic Time Using JWST data
Understanding the complex co-evolution of active galactic nuclei (AGN) and their host galaxies across cosmic time remains a fundamental challenge, particularly in identifying how the physical…The Broad-Line Region Size-Luminosity Relation in AGN Constrained by the Viewing Angle with the FRADO Model
We investigate the H$β$ broad-line region (BLR) size-luminosity ($R_{\rm BLR}$-$L_{5100}$) relation of active galactic nuclei (AGN) using a Bayesian viewing angle inference framework based on the…Underdamped Stochastic Optimal Transport with Landauer boundary conditions: machine learning and analytical solution
Finding optimal transport protocols for underdamped stochastic processes is a difficult yet important problem in control theory.Characterizing $\pT$-differential Radial-Flow Fluctuations in Au+Au Collisions at FAIR with a Multi-Phase Transport Model
We report the first predictions of the transverse-momentum ($\pT$)-differential radial-flow fluctuation observable, $\vzpT$, in Au+Au collisions at the top SIS100 energy, $\snn=4.9$~GeV, which will…Quantum Bernstein--Kolmogorov--Arnold approximation
This paper addresses the expressivity and representation gap in Quantum Neural Networks by establishing a quantum analogue of the classical Kolmogorov--Arnold representation theorem.Windowed Catodyne Measurements: Continuum Approximation versus Exact Discrete Photon-Number Treatment
We analyze a family of measurements obtained by retaining only a finite window of the photon-sum variable in catodyne detection, where a Schrödinger cat state serves as the local oscillator.Quantum machine learning geospatial time-series by seasonal encoding
Quantum data reuploading models can increase the expressive capacity of variational quantum models, but do not necessarily improve predictive performance.Simulating two-Dimensional decaying vortex structure with the Carleman-Lattice-Boltzmann method
We perform a numerical study of the free decay of two-dimensional nonlinear vortex structures using the second-order-truncated Carleman-Lattice Boltzmann method (CLB2).Mathematical foundations of second quantization: an introduction through spin-boson models
These lecture notes originate from a one-semester course on the mathematical foundations of second quantization, first given at the Department of Physics of the Friedrich-Alexander-Universität…
