Kavli Affiliate: Long Zhang | First 5 Authors: Zhiyan Wang, Zhiyan Wang, , , | Summary: We investigate the second order R’enyi entanglement entropy at the quantum critical point of spin-1/2 antiferromagnetic Heisenberg model on a columnar dimerized square lattice. The universal constant $gamma$ in the area-law scaling $S_2(ell) = alphaell – gamma$ is found […]
