Conserved quantities in non-Hermitian systems via vectorization method
Kaustubh S. Agarwal, Jacob Muldoon, Yogesh N. Joglekar
Open classical and quantum systems have attracted great interest in the past two decades. These include systems described by non-Hermitian Hamiltonians with parity-time $(\mathcal{…
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…
-symmetry breaking in a Kitaev chain with one pair of gain-loss potentials
Kaustubh S. Agarwal, Yogesh N. Joglekar
Parity-time () symmetric systems are classical, gain-loss systems whose dynamics are governed by non-Hermitian Hamiltonians with exceptional-point (EP) degeneracies.…
Raising the transition threshold by strong coupling to neutral chains
Kaustubh S. Agarwal, Rajeev K. Pathak, Yogesh N. Joglekar
The symmetry breaking threshold in discrete realizations of systems with balanced gain and loss is determined by the effective coupling between the gain and loss sit…
