Entanglement in Cosmology
Konstantinos Boutivas, Dimitrios Katsinis, Georgios Pastras +1
We compute the evolution of the entanglement entropy for a massless field within a spherical region throughout the inflationary period and the subsequent era of radiation dominatio…
Entanglement of Harmonic Systems in Squeezed States
Dimitrios Katsinis, Georgios Pastras, Nikolaos Tetradis
The entanglement entropy of a free scalar field in its ground state is dominated by an area law term. It is noteworthy, however, that the study of entanglement in scalar field theo…
Entanglement and Expansion
Konstantinos Boutivas, Georgios Pastras, Nikolaos Tetradis
We study the entanglement entropy resulting from tracing out local degrees of freedom of a quantum scalar field in an expanding universe. It is known that when field modes become s…
