Chiral Bosonic Topological Insulator on the Honeycomb Lattice with Anisotropic Interactions
Amrita Ghosh, Eytan Grosfeld
We study hard-core bosons on the honeycomb lattice in the presence of anisotropic nearest-neighbor repulsive interactions. Using a quantum Monte Carlo (QMC) technique, we extract t…
Weak topological insulating phases of hard-core-bosons on the honeycomb lattice
Amrita Ghosh, Eytan Grosfeld
We study the phases of hard-core-bosons on a two-dimensional periodic honeycomb lattice in the presence of an on-site potential with alternating sign along the different y-layers o…
Mixed-order transition and tricritical point associated with checkerboard supersolidity in the two-dimensional model
Amrita Ghosh, Satyaki Kar, Sudhakar Yarlagadda
We use Quantum Monte Carlo method employing stochastic-series-expansion technique to study the ground state properties of the model on a square lattice. We find that, awa…
Study of long-range orders of hard-core bosons coupled to cooperative normal modes in two-dimensional lattices
Amrita Ghosh, Sudhakar Yarlagadda
Understanding the microscopic mechanism of coexisting long-range orders (such as lattice supersolidity) in strongly correlated systems is a subject of immense interest. We study th…
