Algebraic maximum violation of the Leggett-Garg inequality in a two-level system under PT symmetric dynamics

H. S. Karthik, Akshata Shenoy Hejamadi, A. R. Usha Devi

We investigate the three-term Leggett-Garg inequality (LGI) for a two-level quantum system undergoing parity-time (PT ) symmetric dynamics governed by a non-Hermitian Hamiltonian,…
