Adiabatic loading of one-dimensional SU(N) alkaline earth fermions in optical lattices
Lars Bonnes, Kaden R. A. Hazzard, Salvatore R. Manmana +2
Ultracold fermionic alkaline earth atoms confined in optical lattices realize Hubbard models with internal SU(N) symmetries, where N can be as large as ten. Such systems are expect…
Half-Vortex Unbinding and Ising Transition in Constrained Superfluids
Lars Bonnes, Stefan Wessel
We analyze the thermodynamics of the atomic and (nematic) pair superfluids appearing in the attractive two-dimensional Bose-Hubbard model with a three-body hard-core constraint tha…
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…
Polar Molecules with Three-Body Interactions on the Honeycomb Lattice
Lars Bonnes, Hanspeter Büchler, Stefan Wessel
We study the phase diagram of ultra-cold bosonic polar molecules loaded on a two-dimensional optical lattice of hexagonal symmetry controlled by external electric and microwave fie…
