Entanglement entropies of an interval for the massless scalar field in the presence of a boundary
Benoit Estienne, Yacine Ikhlef, Andrei Rotaru +1
We study the entanglement entropies of an interval for the massless compact boson either on the half line or on a finite segment, when either Dirichlet or Neumann boundary conditio…
Rényi entropies for one-dimensional quantum systems with mixed boundary conditions
Benoit Estienne, Yacine Ikhlef, Andrei Rotaru
We present a general method for calculating Rényi entropies in the ground state of a one-dimensional critical system with mixed open boundaries, for an interval starting at one of…
The operator algebra of cyclic orbifolds
Benoit Estienne, Yacine Ikhlef, Andrei Rotaru
We identify the maximal chiral algebra of conformal cyclic orbifolds. In terms of this extended algebra, the orbifold is a rational and diagonal conformal field theory, provided th…
Second Rényi entropy and annulus partition function for one-dimensional quantum critical systems with boundaries
Benoit Estienne, Yacine Ikhlef, Andrei Rotaru
We consider the entanglement entropy in critical one-dimensional quantum systems with open boundary conditions. We show that the second Rényi entropy of an interval away from the b…
