Meson content of entanglement spectra after integrable and nonintegrable quantum quenches
Johannes Knaute
We use tensor network simulations to calculate the time evolution of the lower part of the entanglement spectrum and return rate functions after global quantum quenches in the Isin…
A quantum information perspective on meson melting
Mari Carmen Banuls, Michal P. Heller, Karl Jansen +2
We propose to use quantum information notions to characterize thermally induced melting of nonperturbative bound states at high temperatures. We apply tensor networks to investigat…
Thermalization in Quenched Open Quantum Cosmology
Subhashish Banerjee, Sayantan Choudhury, Satyaki Chowdhury +3
In this article, we study the quantum field theoretic generalization of the Caldeira-Leggett model in general curved space-time considering interactions between two scalar fields i…
From spin chains to real-time thermal field theory using tensor networks
Mari Carmen Banuls, Michal P. Heller, Karl Jansen +2
One of the most interesting directions in theoretical high-energy and condensed-matter physics is understanding dynamical properties of collective states of quantum field theories.…
Path integral optimization as circuit complexity
Hugo A. Camargo, Michal P. Heller, Ro Jefferson +1
Early efforts to understand complexity in field theory have primarily employed a geometric approach based on the concept of circuit complexity in quantum information theory. In a p…
