Dissipative Effects on the Superfluid to Insulator Transition in Mixed-dimensional Optical Lattices
E. Malatsetxebarria, Zi Cai, U. Schollwoeck +1
We study the superfluid to Mott insulator transition of a mixture of heavy bosons and light fermions loaded in an optical lattice. We focus on the effect of the light fermions on t…
Competing orders in the 2D half-filled SU(2N) Hubbard model through the pinning field quantum Monte-Carlo simulations
Da Wang, Yi Li, Zi Cai +3
We non-perturbatively investigate the ground state magnetic properties of the 2D half-filled SU() Hubbard model in the square lattice by using the projector determinant quantum…
Exotic phases of interacting p-band bosons
F. Hébert, Zi Cai, V. G. Rousseau +3
We study a model of interacting bosons that occupy the first excited p-band states of a two-dimensional optical lattice. In contrast to the much studied single band Bose-Hubbard Ha…
Algebraic versus exponential decoherence in dissipative many-particle systems
Zi Cai, Thomas Barthel
The interplay between dissipation and internal interactions in quantum many-body systems gives rise to a wealth of novel phenomena. Here we investigate spin-1/2 chains with uniform…
Unconventional states of bosons with synthetic spin-orbit coupling
Xiangfa Zhou, Yi Li, Zi Cai +1
Spin-orbit coupling with bosons gives rise to novel properties that are absent in usual bosonic systems. Under very general conditions, the conventional ground state wavefunctions…
