Nonlinear Non-Hermitian Landau-Zener-Stückelberg-Majorana interferometry
Xin Wang, H. D. Liu, L. B. Fu
In this work, we have studied the non-Hermitian nonlinear LZSM interferometry in a non-Hermitian N-body interacting boson system in which the non-Hermicity is from the nonreciproca…
Bhatia-Davis formula in the quantum speed limit
Jing Liu, Zibo Miao, Libin Fu +1
The Bhatia-Davis theorem provides a useful upper bound for the variance in mathematics, and in quantum mechanics, the variance of a Hamiltonian is naturally connected to the quantu…
Coherent-State Approach for Majorana representation
H. D. Liu, L. B. Fu, Xiaoguang Wang
By representing a quantum state and its evolution with the majorana stars on the Bloch sphere, the Majorana representation (MR) provide us an intuitive way to study a physical syst…
Many-body quantum coherence and interaction blockade in Josephson-linked Bose-Einstein condensates
Chaohong Lee, Libin Fu, Yuri S. Kivshar
We study many-body quantum coherence and interaction blockade in two Josephson-linked Bose-Einstein condensates. We introduce universal operators for characterizing many-body coher…
