Non-Hermitian Linear Response Theory
Lei Pan, Xin Chen, Yu Chen +1
Linear response theory lies at the heart of quantum many-body physics because it builds up connections between the dynamical response to an external probe and correlation functions…
Wannier basis method for KAM effect in quantum mechanics
Chao Yin, Yu Chen, Biao Wu
The effect of Kolmogorov-Arnold-Moser (KAM) theorem in quantum systems is manifested in dividing eigenstates into regular and irregular states. We propose an effective method based…
Constraints on the energy spectrum of non-Hermitian models in open environments
Jonatan Melkær Midtgaard, Zhigang Wu, Yu Chen
Motivated by recent progress on non-Hermitian topological band theories, we study the energy spectrum of a generic two-band non-Hermitian Hamiltonian. We prove rigorously that the…
Superradiant Mott Transition
Yu Chen
The combination of strong correlation and emergent lattice can be achieved when quantum gases are confined in a superradiant Fabry-Perot cavity. In addition to the discoveries of e…
