Crystalline conductance and absolutely continuous spectrum of 1D samples
Laurent Bruneau, Yoram Last, Vojkan Jaksic +1
We characterize the absolutely continuous spectrum of half-line one-dimensional Schrödinger operators in terms of the limiting behavior of the Crystaline Landauer-Büttiker conducta…
An [imaginary time] Schrödinger approach to mean field games
Igor Swiecicki, Thierry Gobron, Denis Ullmo
Mean Field Games (MFG) provide a theoretical frame to model socio-economic systems. In this letter, we study a particular class of MFG which shows strong analogies with the {\em no…
Dust as interstellar catalyst - II. How chemical desorption impacts the gas
S. Cazaux, M. Minissale, F. Dulieu +1
Context. Interstellar dust particles, which represent 1% of the total mass, are recognized to be very powerful interstellar catalysts in star-forming regions. The presence of dust…
Dynamical properties of the sine-Gordon quantum spin magnet Cu-PM at zero and finite temperature
Alexander C. Tiegel, Andreas Honecker, Thomas Pruschke +4
The material copper pyrimidine dinitrate (Cu-PM) is a quasi-one-dimensional spin system described by the spin-1/2 XXZ Heisenberg antiferromagnet with Dzyaloshinskii-Moriya interact…
Thermodynamic properties of highly frustrated quantum spin ladders: influence of many-particle bound states
A. Honecker, S. Wessel, R. Kerkdyk +3
Quantum antiferromagnets have proven to be some of the cleanest realizations available for theoretical, numerical, and experimental studies of quantum fluctuation effects. At finit…
Dust as interstellar catalyst I. Quantifying the chemical desorption process
M. Minissale, F. Dulieu, S. Cazaux +1
Context. The presence of dust in the interstellar medium has profound consequences on the chemical composition of regions where stars are forming. Recent observations show that man…
Scattering in Twisted Yangians
Jean Avan, Anastasia Doikou, Nikos Karaiskos
We study the bulk and boundary scattering of the sl(N) twisted Yangian spin chain via the solution of the Bethe ansatz equations in the thermodynamic limit. Explicit expressions fo…
Quantized conductance through the quantum evaporation of bosonic atoms
D. J. Papoular, L. P. Pitaevskii, S. Stringari
We analyze theoretically the quantization of conductance occurring with cold bosonic atoms trapped in two reservoirs connected by a constriction with an attractive gate potential.…
Lagrangian and Hamiltonian structures in an integrable hierarchy and space-time duality
Jean Avan, Vincent Caudrelier, Anastasia Doikou +1
We define and illustrate the novel notion of dual integrable hierarchies, on the example of the nonlinear Schrödinger (NLS) hierarchy. For each integrable nonlinear evolution equat…
Quasi-MLE for quadratic ARCH model with long memory
Ieva Grublytė, Donatas Surgailis, Andrius Škarnulis
We discuss parametric quasi-maximum likelihood estimation for quadratic ARCH process with long memory introduced in Doukhan et al. (2015) and Grublytė and Škarnulis (2015) with con…
Phantom distribution functions for some stationary sequences
Paul Doukhan, Adam Jakubowski, Gabriel Lang
The notion of a phantom distribution function (phdf) was introduced by O'Brien (1987). We show that the existence of a phdf is a quite common phenomenon for stationary weakly depen…
Categorical actions on unipotent representations I. Finite unitary groups
Olivier Dudas, Michela Varagnolo, Eric Vasserot
Using Harish-Chandra induction and restriction, we construct a categorical action of a Kac-Moody algebra on the category of unipotent representations of finite unitary groups in no…
Entropic fluctuations in Gaussian dynamical systems
Vojkan Jaksic, Claude-Alain Pillet, Armen Shirikyan
We study non-equilibrium statistical mechanics of a Gaussian dynamical system and compute in closed form the large deviation functionals describing the fluctuations of the entropy…
Massless renormalization group flow in SU(N) perturbed conformal field theory
P. Lecheminant
We investigate the infrared properties of SU(N) conformal field theory perturbed by its adjoint primary field in 1+1 dimensions. The latter field theory is shown to govern the…
Phases of one-dimensional SU(N) cold atomic Fermi gases --from molecular Luttinger liquids to topological phases
S. Capponi, P. Lecheminant, K. Totsuka
Alkaline-earth and ytterbium cold atomic gases make it possible to simulate SU(N)-symmetric fermionic systems in a very controlled fashion. Such a high symmetry is expected to give…
ESR modes in a Strong-Leg Ladder in the Tomonaga-Luttinger Liquid Phase
M. Ozerov, M. Maksymenko, J. Wosnitza +6
Magnetic excitations in the strong-leg quantum spin ladder compound (CHN)CuBr (known as DIMPY) in the field-induced Tomonaga-Luttinger spin liquid phase are stud…
Dynamic and stochastic systems as a framework for metaphysics and the philosophy of science
Christian List, Marcus Pivato
Scientists often think of the world (or some part of it) as a dynamical system, a stochastic process, or a generalization of such a system. Prominent examples of systems are (i) th…
Helimagnetic thin films: surface reconstruction, surface spin-waves and magnetization
Sahbi El Hog, H. T. Diep
Quantum properties of a helimagnetic thin film of simple cubic lattice with Heisenberg spin model are studied using the Green's function method. We find that the spin configuration…
Almost universal codes achieving ergodic MIMO capacity within a constant gap
Laura Luzzi, Roope Vehkalahti
This work addresses the question of achieving capacity with lattice codes in multi-antenna block fading channels when the number of fading blocks tends to infinity. A design criter…
Empirical central limit theorem for cluster functionals without mixing
Paul Doukhan, José Gregorio Gómez
We prove central limit theorems (CLT) for empirical processes of extreme values cluster functionals as in Drees and Rootzén (2010). We use coupling properties enlightened for Dedec…
Slavnov and Gaudin-Korepin formulas for models without symmetry: the XXX chain on the segment
S. Belliard, R. A. Pimenta
We consider the isotropic spin Heisenberg chain with the most general integrable boundaries. The scalar product between the on-shell Bethe vector and its off-shell du…
Empirical Coordination with Channel Feedback and Strictly Causal or Causal Encoding
Maël Le Treust
In multi-terminal networks, feedback increases the capacity region and helps communication devices to coordinate. In this article, we deepen the relationship between coordination a…
Empirical Coordination with Two-Sided State Information and Correlated Source and State
Maël Le Treust
The coordination of autonomous agents is a critical issue for decentralized communication networks. Instead of transmitting information, the agents interact in a coordinated manner…
