Dynamical topology of chiral and nonreciprocal state transfers in a non-Hermitian quantum system
Pengfei Lu, Yang Liu, Qifeng Lao +6
The fundamental concept underlying topological phenomena posits the geometric phase associated with eigenstates. In contrast to this prevailing notion, theoretical studies on time-…

Experimental demonstration of enhanced violations of Leggett-Garg inequalities in a -symmetric trapped-ion qubit
Pengfei Lu, Xinxin Rao, Teng Liu +4
The Leggett-Garg inequality (LGI) places a bound for the distinction between quantum systems and classical systems. Despite that the tests of temporal quantum correlations on LGIs…

Quantum simulation of a general anti-PT-symmetric Hamiltonian with a trapped ion qubit
Ji Bian, Pengfei Lu, Teng Liu +7
Non-Hermitian systems satisfying parity-time (PT) symmetry have aroused considerable interest owing to their exotic features. Anti-PT symmetry is an important counterpart of the PT…
