Observing quantum phase transitions at non-zero temperature: non-analytic behavior of order-parameter correlation times
István Csépányi, Giuseppe Del Vecchio Del Vecchio, Benjamin Doyon +1
Phase transitions occur when a macroscopic number of local degrees of freedom coherently change their behavior. In ground states of quantum many-body systems, phase transitions due…
Twist fields in many-body physics
Benjamin Doyon
The notion of twist fields has played a fundamental role in many-body physics. It is used to construct the so-called disorder parameter for the study of phase transitions in the cl…
Nonlinear projection for ballistic correlation functions: a formula in terms of minimal connected covers
Benjamin Doyon
In many-body systems, the dynamics is governed, at large scales of space and time, by the hydrodynamic principle of projection onto the conserved densities admitted by the model. T…
Rigorous bound on hydrodynamic diffusion for chaotic open spin chains
Dimitrios Ampelogiannis, Benjamin Doyon
The emergence of diffusion is one of the deepest physical phenomena observed in many-body interacting, chaotic systems. But establishing rigorously that correlation functions, say…
Clustering of higher order connected correlations in C dynamical systems
Dimitrios Ampelogiannis, Benjamin Doyon
In the context of dynamical systems, we consider a locally compact group acting by -automorphisms on a C algebra of observables, and assume a state…
Bi-partite entanglement entropy in integrable models with backscattering
O. A. Castro-Alvaredo, B. Doyon
In this paper we generalise the main result of a recent work by J. L. Cardy and the present authors concerning the bi-partite entanglement entropy between a connected region and it…
