Quantum phase transitions in the Kane-Mele-Hubbard model
M. Hohenadler, Z. Y. Meng, T. C. Lang +3
We study the two-dimensional Kane-Mele-Hubbard model at half filling by means of quantum Monte Carlo simulations. We present a refined phase boundary for the quantum spin liquid. T…
Geometry fluctuations in a two-dimensional quantum antiferromagnet
Anuradha Jagannathan, Benoit Douçot, Attila Szallas +1
The paper considers the effects of random fluctuations of the local spin connectivities (fluctuations of the geometry) on ground state properties of a two-dimensional quantum antif…
Generic First-Order vs. Continuous Quantum Nucleation of Supersolidity
Lars Bonnes, Stefan Wessel
We analyze the nucleation of supersolid order out of the superfluid ground state of bosons on the triangular lattice. While the stability of supersolidity against phase separation…
Supersolid Polar Molecules beyond Pairwise Interactions
Lars Bonnes, Stefan Wessel
We explore the phase diagram of ultracold bosonic polar molecules confined to a planar optical lattice of triangular geometry. External static electric and microwave fields can be…
Pair Superfluidity of Three-Body Constrained Bosons in Two Dimensions
Lars Bonnes, Stefan Wessel
We examine the equilibrium properties of lattice bosons with attractive on-site interactions in the presence of a three-body hard-core constraint that stabilizes the system against…
Two-particle decay and quantum criticality in dimerized antiferromagnets
L. Fritz, R. L. Doretto, S. Wessel +3
In certain Mott-insulating dimerized antiferromagnets, triplet excitations of the paramagnetic phase can decay into the two-particle continuum. When such a magnet undergoes a quant…
