Entanglement entropy in lattice gauge theories
P. V. Buividovich, M. I. Polikarpov
We report on the recent progress in theoretical and numerical studies of entanglement entropy in lattice gauge theories. It is shown that the concept of quantum entanglement betwee…
Interacting Field Theories in de Sitter Space are Non-Unitary
Emil T. Akhmedov, P. V. Buividovich
It is well known that there should be a total cancellation of the IR divergences in unitary interacting field theories, such as QED and gravity. The cancellation should be at all o…
Finite-temperature chiral condensate and low-lying Dirac eigenvalues in quenched SU(2) lattice gauge theory
P. V. Buividovich, E. V. Luschevskaya, M. I. Polikarpov
The spectrum of low-lying eigenvalues of overlap Dirac operator in quenched SU(2) lattice gauge theory with tadpole-improved Symanzik action is studied at finite temperatures in th…
Numerical study of entanglement entropy in SU(2) lattice gauge theory
P. V. Buividovich, M. I. Polikarpov
The entropy of entanglement between a three-dimensional slab of thickness l and its complement is studied numerically for four-dimensional SU(2) lattice gauge theory. We find a sig…
Z2 electric strings and center vortices in SU(2) lattice gauge theory
M. I. Polikarpov, P. V. Buividovich
We study the representations of SU(2) lattice gauge theory in terms of sums over the worldsheets of center vortices and Z2 electric strings, i.e. surfaces which open on the Wilson…
