Non-local meta-conformal invariance, diffusion-limited erosion and the XXZ chain
Malte Henkel
Diffusion-limited erosion is a distinct universality class of fluctuating interfaces. Although its dynamical exponent , none of the known variants of conformal invariance can…
Matrix product ansatz for non-equilibrium quantum steady states
D. Karevski, V. Popkov, G. M. Schütz
We present a general construction of matrix product states for stationary density matrices of one-dimensional quantum spin systems kept out of equilibrium through boundary Lindblad…
Physicochemical and thermal modelling of the reaction between a porous pellet and a gas
F Patisson, D Ablitzer
A mathematical model has been developed to simulate the kinetic and thermal behaviour of a porous solid pellet undergoing chemical reaction with a gas. The model describes the chem…
More on the rainbow chain: entanglement, space-time geometry and thermal states
Javier Rodríguez-Laguna, Jérôme Dubail, Giovanni Ramírez +2
The rainbow chain is an inhomogenous exactly solvable local spin model that, in its ground state, displays a half-chain entanglement entropy growing linearly with the system size.…
Local Decay for Weak Interactions with Massless Particles
Jean-Marie Barbaroux, Jérémy Faupin, Jean-Claude Guillot
We consider a mathematical model for the weak decay of the intermediate boson into neutrinos and antineutrinos. We prove that the total Hamiltonian has a unique ground state…
Population processes with unbounded extinction rate conditioned to non-extinction
Nicolas Champagnat, Denis Villemonais
This article studies the quasi-stationary behaviour of population processes with unbounded absorption rate, including one-dimensional birth and death processes with catastrophes an…
