Signatures of Chaos in Non-integrable Models of Quantum Field Theory
Miha Srdinsek, Tomaz Prosen, Spyros Sotiriadis
We study signatures of quantum chaos in (1+1)D Quantum Field Theory (QFT) models. Our analysis is based on the method of Hamiltonian truncation, a numerical approach for the constr…
Non-Equilibrium Steady State of the Lieb-Liniger model: multiple-integral representation of the time evolved many-body wave-function
Spyros Sotiriadis
We continue our study of the emergence of Non-Equilibrium Steady States in quantum integrable models focusing on the expansion of a Lieb-Liniger gas for arbitrary repulsive interac…
Non-Equilibrium Steady State of the Lieb-Liniger model: exact treatment of the Tonks Girardeau limit
Spyros Sotiriadis
Aiming at studying the emergence of Non-Equilibrium Steady States (NESS) in quantum integrable models by means of an exact analytical method, we focus on the Tonks-Girardeau or har…
Out-of-horizon correlations following a quench in a relativistic quantum field theory
Ivan Kukuljan, Spyros Sotiriadis, Gabor Takacs
One of the manifestations of relativistic invariance in non-equilibrium quantum field theory is the "horizon effect" a.k.a. light-cone spreading of correlations: starting from an i…
Correlation Functions of the Quantum Sine-Gordon Model in and out of Equilibrium
Ivan Kukuljan, Spyros Sotiriadis, Gabor Takacs
Complete information on the equilibrium behaviour and dynamics of a quantum field theory (QFT) is provided by multipoint correlation functions. However, their theoretical calculati…
Non-equilibrium quantum transport in presence of a defect: the non-interacting case
Marko Ljubotina, Spyros Sotiriadis, Tomaž Prosen
We study quantum transport after an inhomogeneous quantum quench in a free fermion lattice system in the presence of a localised defect. Using a new rigorous analytical approach fo…
