Commensurate lock-in and incommensurate supersolid phases of hardcore bosons on anisotropic triangular lattices
Sergei V. Isakov, Hong-Chi Chien, Jian-Jheng Wu +4
We investigate the interplay between commensurate lock-in and incommensurate supersolid phases of the hardcore bosons at half-filling with anisotropic nearest-neighbor hopping and…
Exotic phase diagram of a cluster charging model of bosons on the kagome lattice
Sergei V. Isakov, Arun Paramekanti, Yong Baek Kim
We study a model of hard-core bosons on the kagome lattice with short-range hopping () and repulsive interactions (). This model directly maps on to an easy-axis XXZ…
Unusual liquid state of hard-core bosons on the pyrochlore lattice
Argha Banerjee, Sergei V. Isakov, Kedar Damle +1
We study the physics of hard-core bosons with unfrustrated hopping (t) and nearest-neighbor repulsion (V) on the three dimensional pyrochlore lattice. At half-filling, we demonstra…
