Ground state and spectral properties across a Charge Density Wave transition in a triangular-lattice spinless Fermion model
Trithep Devakul, Rajiv R. P. Singh
We study ground state properties and particle excitation spectra across a commensurate charge density wave transition in a system of strongly interacting fermions, using series exp…

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…
