Numerical evidences of a universal critical behavior of 2D and 3D random quantum clock and Potts models
Valentin Anfray, Christophe Chatelain
The random quantum -state clock and Potts models are studied in 2 and 3 dimensions. The existence of Griffiths phases is tested in the 2D case with by sampling the integra…
Optimal design of nanomagnets for on-chip field gradients
William Legrand, Sandrine Lopes, Quentin Schaeverbeke +2
The generation of localized magnetic field gradients by on-chip nanomagnets is important for a variety of technological applications, in particular for spin qubits. To advance beyo…
The role of damping rate amplitude in the synchronization of two coupled oscillators
A. Hamadeh, A. Koujok, I. Medlej +2
We investigate the synchronization phenomenon between two Spin-transfer Torque Nano-Oscillators (STNOs) of different frequencies in two pillar systems under vortex configuration de…
Focusing Gibbs measures with harmonic potential
Tristan Robert, Kihoon Seong, Leonardo Tolomeo +1
In this paper, we study the Gibbs measures associated to the focusing nonlinear Schrödinger equation with harmonic potential on Euclidean spaces. We establish a dichotomy for norma…
Parallel kinetic schemes for conservation laws, with large time steps
Pierre Gerhard, Philippe Helluy, Victor Michel-Dansac +1
We propose a new parallel Discontinuous Galerkin method for the approximation of hyperbolic systems of conservation laws. The method remains stable with large time steps, while kee…
Probing many-body correlations using quantum-cascade correlation spectroscopy
Lorenzo Scarpelli, Cyril Elouard, Mattias Johnsson +7
The radiative quantum cascade, i.e. the consecutive emission of photons from a ladder of energy levels, is of fundamental importance in quantum optics. For example, the two-photon…
Trends in Planetary Science research in the Puna and Atacama desert regions: under-representation of local scientific institutions?
Adrien Tavernier, Gabriel Pinto, Millarca Valenzuela +4
In 2019 while launching a multidisciplinary research project aimed at developing the Puna de Atacama region as a natural laboratory, investigators within the University of Atacama…
Null-controllability of cascade reaction-diffusion systems with odd coupling terms
Kévin Le Balc'h, Takéo Takahashi
In this paper, we consider a nonlinear system of two parabolic equations, with a distributed control in the first equation and an odd coupling term in the second one. We prove that…
Thermal transport properties of the nanocomposite system "porous silicon/ionic liquid"
Pavlo Lishchuk, Alina Vashchuk, Sergiy Rogalsky +4
This paper investigates thermal transport in a nanocomposite system "porous silicon matrix filled with ionic liquid". First, the thermal conductivity and heat capacity of two imida…
Normal forms of -graded -manifolds
Alexei Kotov, Camille Laurent-Gengoux, Vladimir Salnikov
Following recent results of A.K. and V.S. on -graded manifolds, we give several local and global normal forms results for -structures on those, i.e. for differential…
Efficient Convex Zone Merging in Parametric Timed Automata
Étienne André, Dylan Marinho, Laure Petrucci +1
Parametric timed automata are a powerful formalism for reasoning on concurrent real-time systems with unknown or uncertain timing constants. Reducing their state space is a signifi…
Off-centre supermassive black holes in bright central galaxies
Aline Chu, Pierre Boldrini, Joe Silk
Supermassive black holes (SMBHs) are believed to reside at the centre of massive galaxies such as brightest cluster galaxies (BCGs). However, as BCGs experienced numerous galaxy me…
Spin-to-charge conversion by spin pumping in sputtered polycrystalline BiSe
Isabel C Arango, Alberto Anadón, Silvestre Novoa +9
Topological materials are of high interest due to the promise to obtain low power and fast memory devices based on efficient spin-orbit torque switching or spin-orbit magnetic stat…

Xia Huang, Dong Ye
In this paper, we establish discrete Hardy-Rellich inequalities on with and optimal constants, for any . As far as we are aware, these…
Hyperbolicity and fundamental groups of complex quasi-projective varieties
Benoit Cadorel, Ya Deng, Katsutoshi Yamanoi
This paper investigates the relationship between the hyperbolicity of complex quasi-projective varieties and the (topological) fundamental group in the presence of a l…
Wigner dynamics for quantum gases under inhomogeneous gain and loss processes with dephasing
Michele Coppola, Gabriel T. Landi, Dragi Karevski
We present a Wigner function-based approach for the particle density evolution in fermionic and bosonic open quantum many-body systems, including the effects of dephasing. In parti…
