On the entanglement across a cubic interface in 3+1 dimensions
Trithep Devakul, Rajiv R. P. Singh
We calculate the area, edge and corner Renyi entanglement entropies in the ground state of the transverse-field Ising model, on a simple-cubic lattice, by high-field and low-field…
Quantum Critical Universality and Singular Corner Entanglement Entropy of Bilayer Heisenberg-Ising model
Trithep Devakul, Rajiv R. P. Singh
We consider a bilayer quantum spin model with anisotropic intra-layer exchange couplings. By varying the anisotropy, the quantum critical phenomena changes from XY to Heisenberg to…
Resistance between two nodes in general position on an fan network
J. W. Essam, Zhi-Zhong Tan, F. Y. Wu
The resistance between two nodes in general position on a fan network with n radial lines and m transverse lines is determined. Also a similar result of Izmailian, Kenna and Wu [7]…
The two-point resistance of a cobweb with a superconducting boundary
Zhi-Zhong Tan, J. W. Essam, F. Y. Wu
We consider the problem of two-point resistance on an m x n cobweb network with a superconducting boundary, which is topologically equivalent to a geographic globe. We deduce a con…
