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…

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{…
