Chiral phases of two-dimensional hard-core bosons with frustrated ring-exchange
Daniel Huerga, Jorge Dukelsky, Nicolas Laflorencie +1
We study the zero temperature phase diagram of two-dimensional hard-core bosons on a square lattice with nearest neighbour and plaquette (ring-exchange) hoppings, at arbitrary dens…

Composite Boson Mapping for Lattice Boson Systems
Daniel Huerga, Jorge Dukelsky, Gustavo E. Scuseria
We present a canonical mapping transforming physical boson operators into quadratic products of cluster composite bosons that preserves matrix elements of operators when a physical…
