Entanglement Content of Quantum Particle Excitations I. Free Field Theory
Olalla A. Castro-Alvaredo, Cecilia De Fazio, Benjamin Doyon +1
We evaluate the entanglement entropy of a single connected region in excited states of one-dimensional massive free theories with finite numbers of particles, in the limit of large…
Entanglement Content of Quasi-Particle Excitations
Olalla A. Castro-Alvaredo, Cecilia De Fazio, Benjamin Doyon +1
We investigate the quantum entanglement content of quasi-particle excitations in extended many-body systems. We show that such excitations give an additive contribution to the bi-p…
LeClair-Mussardo series for two-point functions in Integrable QFT
B. Pozsgay, I. M. Szécsényi
We develop a well-defined spectral representation for two-point functions in relativistic Integrable QFT in finite density situations, valid for space-like separations. The resulti…
