Finite-size scaling on the torus with periodic projected entangled-pair states
Gleb Fedorovich, Lukas Devos, Jutho Haegeman +3
An efficient algorithm is constructed for contracting two-dimensional tensor networks under periodic boundary conditions. The central ingredient is a novel renormalization step tha…

First order Quantum Hall to Wigner crystal phase transition on a triangular lattice: an iDMRG study
Gleb Fedorovich, Clemens Kuhlenkamp, Atac Imamoglu +1
In this work we study a system of interacting fermions on a triangular lattice in the presence of an external magnetic field. We neglect spin and fix a density of one third, with o…
