Essential role of quantum speed limit in violation of Leggett-Garg inequality across a PT-transition
Anant V. Varma, Jacob E. Muldoon, Sourav Paul +2
We study Leggett-Garg inequality (LGI) of a two level system (TLS) undergoing non-Hermitian dynamics governed by a non-linear Bloch equation (derived in J. Phys. A: Math. Theor. 54…
Photonic quantum simulations of coupled -symmetric Hamiltonians
Nicola Maraviglia, Patrick Yard, Ross Wakefield +9
Parity-time () symmetric Hamiltonians are generally non-Hermitian and give rise to exotic behaviour in quantum systems at exceptional points, where eigenvectors coalesce. The r…
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{…
Non-Markovian anti-parity-time symmetric systems: theory and experiment
Andrew Wilkey, Joseph Suelzer, Yogesh N. Joglekar +1
Open systems with anti parity-time (anti -) or symmetry exhibit a rich phenomenology absent in their Hermitian counterparts. To date all model systems…
