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…
Weak Quantum Chaos
Ivan Kukuljan, Sašo Grozdanov, Tomaž Prosen
Out-of-time-ordered correlation functions (OTOC's) are presently being extensively debated as quantifiers of dynamical chaos in interacting quantum many-body systems. We argue that…
