Quantum theory provides an extensive framework for the description of the equilibrium
properties of quantum matter. Yet experiments in quantum simulators have now opened up …

Nonequilibrium states of closed quantum many-body systems defy a thermodynamic
description. As a consequence, constraints such as the principle of equal a priori …

The theory of phase transitions represents a central concept for the characterization of
equilibrium matter. In this work we study experimentally an extension of this theory to the …

A bstract It was noticed many years ago, in the framework of massless RG flows, that the
irrelevant composite operator\(\mathrm {T}\overline {\mathrm {T}}\), built with the components …

A phase transition indicates a sudden change in the properties of a large system. For
temperature-driven phase transitions this is related to nonanalytic behavior of the free …

We study the nonequilibrium time evolution of a variety of one-dimensional (1D) and two-
dimensional (2D) systems (including SSH model, Kitaev-chain, Haldane model, p+ ip …

We study the statistics of the work done on a quantum critical system by quenching a control
parameter in the Hamiltonian. We elucidate the relation between the probability distribution …

We investigate the dynamics following sudden quenches across quantum critical points
belonging to different universality classes. Specifically, we use matrix product state methods …

A bstract We develop a novel nonperturbative approach to a class of three-point functions in
planar\(\mathcal {N}\)= 4 SYM based on Thermodynamic Bethe Ansatz (TBA). More …

A bstract We derive a set of integral equations of the TBA type for the generalized cusp
anomalous dimension, or the quark antiquark potential on the three sphere, as a function of …
