Investigation of Complex ϕ 4 Theory at Finite Density in Two Dimensions Using TRG

Abstract We study the two-dimensional complex ϕ 4 theory at finite chemical potential using the tensor renormalization group. This model exhibits the Silver Blaze phenomenon in which bulk observables are independent of the chemical potential below the critical point. Since it is expected to be a dir...
