Topological phase diagrams of exactly solvable non-Hermitian interacting Kitaev chains
Sharareh Sayyad, José L. Lado
Abstract
The interacting phase diagram of a non-Hermitian one-dimensional model featuring topologically different phases is demonstrated. Furthermore, the exact solution in the integrable regime, which has been extended to the nonintegrable regime by employing exact diagonalization and matrix product state methods, is presented. The present results are expected to pave a new pathway toward characterizing non-Hermitian topology in realistic interacting quantum many-body systems.
