Topological Transitions with an Imaginary Aubry-Andre-Harper Potential
Bofeng Zhu, Li-Jun Lang, Qiang Wang +2
We study one-dimensional lattices with imaginary-valued Aubry-Andre-Harper (AAH) potentials. Such lattices can host edge states with purely imaginary eigenenergies, which differ fr…

Quantum circuit for measuring an operator's generalized expectation values and its applications to non-Hermitian winding numbers
Ze-Hao Huang, Peng He, Li-Jun Lang +1
We propose a general quantum circuit based on the swap test for measuring the quantity of an arbitrary operator with respect to two quantum stat…
