Gaussian eigenstate pinning in non-Hermitian quantum mechanics
Qi-Bo Zeng, Rong Lü
We study a one-dimensional system subjected to a linearly varying imaginary vector potential, which is described by the single-particle continuous Schrödinger equation and is analy…
Real spectra and phase transition of skin effect in nonreciprocal systems
Qi-Bo Zeng, Rong Lü
We study the one-dimensional nonreciprocal lattices with real nearest neighboring hopping and find that the energy spectra under open boundary conditions can be entirely real or im…
Evolution of spectral topology in one-dimensional long-range nonreciprocal lattices
Qi-Bo Zeng, Rong Lü
We investigate the spectral topology of one-dimensional lattices where the nonreciprocal hoppings within the nearest neighboring sites are the same. For the purely off-diagon…
Topological phases and Anderson localization in off-diagonal mosaic lattices
Qi-Bo Zeng, Rong Lü
We introduce a one-dimensional lattice model whose hopping amplitudes are modulated for equally spaced sites. Such mosaic lattice exhibits many interesting topological and localiza…
Geometrical meaning of winding number and its characterization of topological phases in one-dimensional chiral non-Hermitian systems
Chuanhao Yin, Hui Jiang, Linhu Li +2
We unveil the geometrical meaning of winding number and utilize it to characterize the topological phases in one-dimensional chiral non-Hermitian systems. While chiral symmetry ens…
Anderson localization in the Non-Hermitian Aubry-André-Harper model with physical gain and loss
Qi-Bo Zeng, Shu Chen, Rong Lü
We investigate the Anderson localization in non-Hermitian Aubry-André-Harper (AAH) models with imaginary potentials added to lattice sites to represent the physical gain and loss d…
