Two-dimensional anisotropic non-Hermitian Lieb lattice
L. C. Xie, H. C. Wu, X. Z. Zhang +2
We study an anisotropic two-dimensional non-Hermitian Lieb lattice, where the staggered gain and loss present in the horizontal and vertical directions, respectively. The intra-cel…

Probing the superfluid-insulator phase transition by a non-Hermitian external field
X. Z. Zhang, Z. Song
We study the response of a thermal state of the Hubbard-like system to either global or local non-Hermitian perturbation, which coalesces the degenerate ground state within the $U(…
