Determination of the ground state polarizability of Dy near 530 nm
Alexandre Journeaux, Maxime Lecomte, Julie Veschambre +3
Open-shell lanthanide atoms, and dysprosium in particular, combine a large ground-state angular momentum with dense electronic spectra, making their dynamical polarizability strong…
Entropy production versus memory effects in two-level open quantum systems
Guillaume Théret, Dominique Sugny, Camille L. Latune
We compare several definitions of entropy production rate introduced in the literature from a large variety of situations and motivations, and then analyze their relations with mem…
Dynamical system approach to the spectral (in)stability of black holes under localised potential perturbations
T. Torres, S. R. Dolan
The aim of this work is to improve understanding of the resonant spectra of black holes under perturbations arising from e.g. compact objects or accretion disks in their vicinity.…
Irreversible thermalization vs reversible dynamics mediated by anomalous correlators: Wave turbulence theory and experiments in optical fibers
T. Torres, J. Garnier, L. Zanaglia +8
We theoretically and experimentally investigate spontaneous self-organization in a conservative (Hamiltonian) turbulent wave system, operating far from thermodynamic equilibrium. O…
Spatio-temporal equilibrium thermodynamics of guided optical waves at positive and negative temperatures
Lucas Zanaglia, Josselin Garnier, Claire Michel +5
Optical thermalization has been recently studied in the 2D spatial evolution of (quasi-)monochromatic light waves propagating in multimode waveguides. Here, we investigate the spat…
Ulrich and Instanton Bundles on Special Cubic Fourfolds
Gianfranco Casnati, Daniele Faenzi, Federica Galluzzi
We study instanton and Ulrich bundles on hypersurfaces of the projective space, with a focus on special cubic fourfolds and generalized Pfaffians, notably defined by skew-symmetric…
The HITRAN2024 methane update
T. Bertin, I. E. Gordon, R. J. Hargreaves +22
Spectroscopic parameters of methane from many different studies were gathered to improve the HITRAN database towards its 2024 version. After a validation process using high-resolut…
Cluster percolation and dynamical scaling in the Baxter--Wu model
Alexandros Vasilopoulos, Michail Akritidis, Nikolaos G. Fytas +1
We investigate the percolation behavior of Fortuin-Kasteleyn--type clusters in the spin- Baxter--Wu model with three-spin interactions on a triangular lattice. The considered…
Application of perturbation theory to finding vibrational frequencies of a spheroid
M. O. Nestoklon, L. Saviot, S. V. Goupalov
We apply perturbation theory of boundary conditions, originally developed by A.B. Migdal and independently by S.A. Moszkowski for deformed atomic nuclei, to finding eigenfrequencie…
Ionic emissions and activity evolution in comet C/2020 F3 (NEOWISE): Insights from long-slit spectroscopy and photometry
K. Aravind, E. Jehin, S. Hmmidouch +7
Comet C/2020 F3 (NEOWISE) was the brightest comet in the northern hemisphere since C/1995 O1 (Hale-Bopp), providing a unique opportunity to study its composition and spatial distri…
Spatio-temporal thermalization and adiabatic cooling of guided light waves
Lucas Zanaglia, Josselin Garnier, Iacopo Carusotto +3
We propose and theoretically characterize three-dimensional spatio-temporal thermalization of a continuous-wave classical light beam propagating along a multi-mode optical waveguid…
Construction of ergodic IDLA forests in
Nicolas Chenavier, David Coupier, Keenan Penner +1
We prove the existence of infinite-volume IDLA forests in , with , based on a multi-source IDLA protocol. Unlike IDLA aggregates, the laws of the IDLA fore…
Optimization of Workload Mapping and Scheduling in Scaling Heterogeneous HPC Systems: A Systematic Literature Review
Aasish Kumar Sharma, Julian Kunkel
The increasing heterogeneity of High-Performance Computing (HPC) systems, incorporating Central Processing Units (CPUs), Graphics Processing Units (GPUs), Field-Programmable Gate A…
From Brain to Motion: Harnessing Higher-Derivative Mechanics for Neural Control
O. White, F. Buisseret, F. Dierick +1
Optimal Feedback Control (OFC) provides a theoretical framework for goal-directed movements, where the nervous system adjusts actions based on sensory feedback. In OFC, the central…
Dynamics and equilibrium states of infinite systems of lattice bosons
Andreas Deuchert, Jonas Lampart, Marius Lemm
We consider the dynamics of systems of lattice bosons with infinitely many degrees of freedom. We show that their dynamics defines a group of automorphisms on a --algebra intr…
Equivariant spaces of matrices of constant corank one
Ada Boralevi, Daniele Faenzi, Dragoş Frăţilă
We study spaces of matrices coming from irreducible representations of reductive groups over an algebraically closed field of characteristic zero and we completely classify those o…
Higher-rank instantons sheaves on Fano threefolds
Gaia Comaschi, Daniele Faenzi
We define instanton sheaves of higher rank on smooth Fano threefolds X of Picard rank one and show that their topological classification depends on two integers, namely the rank n…
Application of the Pontryagin Maximum Principle to the robust time-optimal control of two-level quantum systems
O. Fresse-Colson, S. Guérin, Xi Chen +1
We study the time-optimal robust control of a two-level quantum system subjected to field inhomogeneities. We apply the Pontryagin Maximum Principle and we introduce a reduced spac…
Unitary Transformations using Robust Optimal Control on a Cold Atom Qudit
E. Flament, N. Ombredane, F. Arrouas +4
In this paper, we design and experimentally implement various robust quantum unitary transformations (gates) acting on -dimensional vectors (qudits) by tuning a single control p…

Benjamin Hinrichs, Jonas Lampart, Javier Valentín Martín
We study the ultraviolet problem for models of a finite-dimensional quantum mechanical system linearly coupled to a bosonic quantum field, such as the (many-)spin boson model or it…
Stochastic Dynamics of Incoherent Branched Flow
Josselin Garnier, Antonio Picozzi, Theo Torres
Waves propagating through weakly disordered smooth linear media undergo a universal phenomenon called branched flow. Branched flow has been observed and studied experimentally in v…
