Free compact boson on branched coverings of the torus
Feihu Liu
We have studied the free compact boson on a -sheeted covering of the torus gluing alone branch cuts. It is interesting because when the branched cuts are chosen to be real,…

Two intervals Rényi entanglement entropy of compact free boson on torus
Feihu Liu, Xiao Liu
We compute the Rényi entanglement entropy of two intervals at equal time in a circle, for the theory of a 2d compact complex free scalar at finite temperature. This is carrie…
