Quantum spin liquid in a kagome lattice spin-1/2 XY model with four-site exchange
Long Dang, Stephen Inglis, Roger G. Melko
We study the ground state phase diagram of a two-dimensional kagome lattice spin-1/2 XY model (J) with a four-site ring exchange interaction (K) using quantum Monte Carlo simulatio…
Phases of lattice hard core bosons in a periodic superlattice
Long Dang, Massimo Boninsegni
We study by Quantum Monte Carlo simulations the phase diagram of lattice hard core bosons with nearest-neighbour repulsive interactions, in the presence of a super-lattice of adsor…
Disorder-induced superfluidity
Long Dang, Massimo Boninsegni, Lode Pollet
We use quantum Monte Carlo simulations to study the phase diagram of hard-core bosons with short-ranged {\it attractive} interactions, in the presence of uniform diagonal disorder.…
Vacancy supersolid of hard-core bosons on the square lattice
Long Dang, Massimo Boninsegni, Lode Pollet
The ground state of hard-core bosons on the square lattice with nearest and next-nearest neighbor repulsion is studied by Quantum Monte Carlo simulations. A supersolid phase with v…
