Exactly solvable -symmetric models in two dimensions
Kaustubh S. Agarwal, Rajeev K. Pathak, Yogesh N. Joglekar
Non-hermitian, -symmetric Hamiltonians, experimentally realized in optical systems, accurately model the properties of open, bosonic systems with balanced, spatially…
PT-symmetric Rabi model: Perturbation theory
Tony E. Lee, Yogesh N. Joglekar
We study a non-Hermitian version of the Rabi model, where a two-level system is periodically driven with an imaginary-valued drive strength, leading to alternating gain and loss. I…
-breaking threshold in spatially asymmetric Aubry-Andre Harper models: hidden symmetry and topological states
Andrew K. Harter, Tony E. Lee, Yogesh N. Joglekar
Aubry-Andre Harper (AAH) lattice models, characterized by reflection-asymmetric, sinusoidally varying nearest-neighbor tunneling profile, are well-known for their topological prope…
