Non-Hermitian heat engine with all-quantum-adiabatic-process cycle
S. Lin, Z. Song
As a quantum device, a quantum heat engine (QHE) is described by a Hermitian Hamiltonian.However, since it is an open system, reservoirs have to be imposed phenomenologically witho…
Quench field sensitivity of two-particle correlation in a Hubbard model
X. Z. Zhang, S. Lin, Z. Song
Short-range interaction can give rise to particle pairing with a short-range correlation, which may be destroyed in the presence of an external field. We study the transition betwe…
Sudden death of particle-pair Bloch oscillation and unidirectional propagation in a one-dimensional driven optical lattice
S. Lin, X. Z. Zhang, Z. Song
We study the dynamics of bound pairs in the extended Hubbard model driven by a linear external field. It is shown that two interacting bosons or singlet fermions with nonzero on-si…
Amplitude control of a quantum state in a non-Hermitian Rice-Mele model driven by an external field
S. Lin, X. Z. Zhang, Z. Song
In the Hermitian regime, a Berry phase is always the real number. It may be imaginary for a non-Hermitian system, which leads to amplitude amplification or attenuation of an evolve…
