Anderson localization in the Non-Hermitian Aubry-André-Harper model with physical gain and loss

  title={Anderson localization in the Non-Hermitian Aubry-Andr{\'e}-Harper model with physical gain and loss},

  journal={Physical Review A},
We investigate the Anderson localization in non-Hermitian Aubry-Andr\'e-Harper (AAH) models with imaginary potentials added to lattice sites to represent the physical gain and loss during the interacting processes between the system and environment. By checking the mean inverse participation ratio (MIPR) of the system, we find that different configurations of physical gain and loss have very different impacts on the localization phase transition in the system. In the case with balanced physical…

Metal-insulator phase transition in a non-Hermitian Aubry-André-Harper model

Non-Hermitian extensions of the Anderson and Aubry-Andre-Harper models are attracting a considerable interest as platforms to study localization phenomena, metal-insulator and topological phase

Breakdown of the correspondence between the real-complex and delocalization-localization transitions in non-Hermitian quasicrystals

The correspondence between the real-complex transition in energy and delocalization-localization transition is well-established in a class of Aubry-Andr´e-Harper model with exponentially

Polaron in a non-Abelian Aubry-André-Harper model with p -wave superfluidity

We theoretically investigate the behavior of a mobile impurity immersed in a one-dimensional quasiperiodic Fermi system with topological $p$-wave superfluidity. This polaron problem is solved by

Winding numbers and generalized mobility edges in non-Hermitian systems

The Aubry-Andre-Harper (AAH) model with a self-dual symmetry plays an important role in studying the Anderson localization. Here we find a self-dual symmetry determining the quantum phase transition

Localization transition, spectrum structure, and winding numbers for one-dimensional non-Hermitian quasicrystals

We develop a general scheme for the study of the localization transition in a general non-Hermitian quasicrystals with both complex phase factor and non-reciprocal hopping, As a consequence, we

Robust quantum boomerang effect in non-Hermitian systems

Anderson localization is a general phenomenon that applies to a variety of disordered physical systems. Recently, a novel manifestation of Anderson localization for wave packets launched with a finite

Skin superfluid, topological Mott insulators, and asymmetric dynamics in an interacting non-Hermitian Aubry-André-Harper model

Non-Hermitian quantum many-body systems are a fascinating subject to be explored. Using the generalized density matrix renormalization group method and complementary exact diagonalization, we

Dimerized non-Hermitian quasicrystal

Non-Hermitian quasicrystals possess PT -symmetry breaking and metal-insulator transitions induced by gain and loss or nonreciprocal effects. In this work, we uncover the dynamical and topological

Ubiquity of the quantum boomerang effect in Hermitian Anderson-localized systems

A particle with finite initial velocity in a disordered potential comes back and in average stops at the original location. This phenomenon dubbed ‘quantum boomerang effect’ (QBE) has been recently

Interplay of non-Hermitian skin effects and Anderson localization in nonreciprocal quasiperiodic lattices

Non-Hermiticity from nonreciprocal hoppings has been shown recently to demonstrate the non-Hermitian skin effect (NHSE) under open boundary conditions (OBCs). Here we study the interplay of this
