Tensor Renormalization Group Centered About a Core Tensor
Wangwei Lan, Glen Evenbly
We propose a modified form of a tensor renormalization group algorithm for evaluating partition functions of classical statistical mechanical models on 2D lattices. This algorithm…

Bulk Fermi surfaces of the Dirac Type-II Semimetallic Candidates VAl3, NbAl3 and TaAl3
K. -W. Chen, X. Lian, Y. Lai +7
We report a de Haas-van Alphen (dHvA) effect study on the Dirac type-II semimetallic candidates \emph{M}Al (where, \emph{M} = V, Nb and Ta). The angular-dependence of their Fer…

Quantum phase diagram of spin- Heisenberg model on the square lattice: an infinite projected entangled-pair state and density matrix renormalization group study
R. Haghshenas, Wang-Wei Lan, Shou-Shu Gong +1
We study the spin- Heisenberg model on the square lattice with the antiferromagnetic nearest-neighbor and the next-nearest-neighbor couplings by using the infinite p…
