Hexagonal Plaquette Spin-spin Interactions and Quantum Magnetism in a Two-dimensional Ion Crystal
Rejish Nath, Marcello Dalmonte, Alexander W Glaetzle +3
We propose a trapped ion scheme en route to realize spin Hamiltonians on a Kagome lattice which, at low energies, are described by emergent Z2 gauge fields, and support a topologic…
Superconducting Vortex Lattices for Ultracold Atoms
O. Romero-Isart, C. Navau, A. Sanchez +2
We propose and analyze a nanoengineered vortex array in a thin-film type-II superconductor as a magnetic lattice for ultracold atoms. This proposal addresses several of the key que…
Majorana Modes in Driven-Dissipative Atomic Superfluids With Zero Chern Number
C. -E. Bardyn, M. A. Baranov, E. Rico +3
We investigate dissipation-induced p-wave paired states of fermions in two dimensions and show the existence of spatially separated Majorana zero modes in a phase with vanishing Ch…
Dissipation-induced d-Wave Pairing of Fermionic Atoms in an Optical Lattice
S. Diehl, W. Yi, A. J. Daley +1
We show how dissipative dynamics can give rise to pairing for two-component fermions on a lattice. In particular, we construct a "parent" Liouvillian operator so that a BCS-type st…
Quantum Field Theory for the Three-Body Constrained Lattice Bose Gas -- Part II: Application to the Many-Body Problem
S. Diehl, M. Baranov, A. J. Daley +1
We analyze the ground state phase diagram of attractive lattice bosons, which are stabilized by a three-body onsite hardcore constraint. A salient feature of this model is an Ising…
Quantum Field Theory for the Three-Body Constrained Lattice Bose Gas -- Part I: Formal Developments
S. Diehl, M. Baranov, A. J. Daley +1
We develop a quantum field theoretical framework to analytically study the three-body constrained Bose-Hubbard model beyond mean field and non-interacting spin wave approximations.…
