Fluctuation of the phase boundary in the six-vertex model with Domain Wall Boundary Conditions: a Monte Carlo study
Ivar Lyberg, Vladimir Korepin, Jacopo Viti
We consider the six-vertex model with Domain Wall Boundary Conditions on a square lattice. Our main interest is the study of the fluctuations of the extremal lattice pa…
The Limit of the Entanglement Entropy
