Supervised learning of an interacting 2D hard-core boson model of a weak topological insulator using correlation functions
Amrita Ghosh, Mugdha Sarkar
We study a system of hard-core bosons on a two-dimensional periodic honeycomb lattice subjected to an on-site potential with alternating signs along -direction, using machine le…
Strong to weak interacting-topological phase transition of bosons on a lattice
Amrita Ghosh, Eytan Grosfeld
We study hard-core bosons on the honeycomb lattice subjected to anisotropic nearest-neighbor hopping along with anisotropic nearest-neighbor repulsion, using a quantum Monte Carlo…
Interaction-driven phase transition in one dimensional mirror-symmetry protected topological insulator
Devendra Singh Bhakuni, Amrita Ghosh, Eytan Grosfeld
Topological crystalline insulators are phases of matter where the crystalline symmetries solely protect the topology. In this work, we explore the effect of many-body interactions…
Study of supersolidity in the two-dimensional Hubbard-Holstein model
A. Ghosh, S. Kar, S. Yarlagadda
We derive an effective Hamiltonian for the two-dimensional Hubbard-Holstein model in the regimes of strong electron-electron and strong electron-phonon interactions by using a nonp…
