Zero dimensional area law in a gapless fermion system

POSTER

Abstract

The entanglement entropy of a gapless fermion subsystem coupled to a gapless bulk by a ``weak link'' is considered. It is demonstrated numerically that each independent weak link contributes an entropy proportional to $\ln{L}$, where $L$ is linear dimension of the subsystem.
