Non-Hermitian Haldane-Hubbard model: Effective description of an open system with balanced gain and loss
Tian-Cheng Yi, Rubem Mondaini
We study the correlated Haldane-Hubbard model with single-particle gain and loss, focusing on its non-Hermitian phase diagram and the ensuing non-unitary dynamic properties. The in…

Two-dimensional polarized superfluids under the prism of the fermion sign problem
Tian-Cheng Yi, Song Cheng, Ian Pilé +2
Understanding if attractive fermions in an unbalanced occupation of its flavors can give rise to a superfluid state in two dimensions (2D), realizing the Fulde-Ferrel-Larkin-Ovchin…
