Conserved quantities, exceptional points, and antilinear symmetries in non-Hermitian systems
Frantisek Ruzicka, Kaustubh S. Agarwal, Yogesh N. Joglekar
Over the past two decades, open systems that are described by a non-Hermitian Hamiltonian have become a subject of intense research. These systems encompass classical wave systems…
Quantum information dynamics in a high-dimensional parity-time-symmetric system
Zhihao Bian, Lei Xiao, Kunkun Wang +5
Non-Hermitian systems with parity-time () symmetry give rise to exceptional points (EPs) with exceptional properties that arise due to the coalescence of eigenvectors…
Conserved quantities in parity-time symmetric systems
Zhihao Bian, Lei Xiao, Kunkun Wang +6
Conserved quantities such as energy or the electric charge of a closed system, or the Runge-Lenz vector in Kepler dynamics are determined by its global, local, or accidental symmet…
Multi-well log-anharmonic oscillators
Miloslav Znojil, František Růžička
Quantum particle is considered confined in a toy-model potential possessing multiple minima. For the specific choice of the family of potentials (in the form of harmonic oscillator…
