Realizing the Hayden-Preskill Protocol with Coupled Dicke Models
Yanting Cheng, Chang liu, Jinkang Guo +3
Hayden and Preskill proposed a thought experiment that Bob can recover the information Alice throws into a black hole if he has a quantum computer entangled with the black hole, an…
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…
