Branch Point Twist Field Correlators in the Massive Free Boson Theory
Davide Bianchini, Olalla A. Castro-Alvaredo
Well-known measures of entanglement in one-dimensional many body quantum systems, such as the entanglement entropy and the logarithmic negativity, may be expressed in terms of the…
Entanglement Entropy from Corner Transfer Matrix in Forrester Baxter non-unitary RSOS models
Davide Bianchini, Francesco Ravanini
Using a Corner Transfer Matrix approach, we compute the bipartite entanglement Rényi entropy in the off-critical perturbations of non-unitary conformal minimal models realised by l…
Entanglement Entropy of Non-Unitary Integrable Quantum Field Theory
Davide Bianchini, Olalla A. Castro-Alvaredo, Benjamin Doyon
In this paper we study the simplest massive 1+1 dimensional integrable quantum field theory which can be described as a perturbation of a non-unitary minimal conformal field theory…
RSOS Quantum Chains Associated with Off-Critical Minimal Models and Parafermions
Davide Bianchini, Elisa Ercolessi, Paul A. Pearce +1
We consider the off-critical perturbation of the general non-unitary minimal models where and are coprime and measures the d…
Entanglement Entropy of Non Unitary Conformal Field Theory
Davide Bianchini, Olalla A. Castro-Alvaredo, Benjamin Doyon +2
In this letter we show that the Rényi entanglement entropy of a region of large size in a one-dimensional critical model whose ground state breaks conformal invariance (such…
