Information scrambling of the dilute Bose gas at low temperature
Chao Yin, Yu Chen
We calculate the quantum Lyapunov exponent and butterfly velocity in the dilute Bose gas at temperature deep in the Bose-Einstein condensation phase. The generalize…
Violation and Revival of Kramers' Degeneracy in Open Quantum Systems
Pengfei Zhang, Yu Chen
Kramers' theorem ensures double degeneracy in the energy spectrum of a time-reversal symmetric fermionic system with half-integer total spin. Here we are now trying to go beyond th…
Stability of Time-Reversal Symmetry Protected Topological Phases
Tian-Shu Deng, Lei Pan, Yu Chen +1
In a closed system, it is well known that the time-reversal symmetry can lead to Kramers degeneracy and protect nontrivial topological states such as quantum spin Hall insulator. I…
Disconnecting a Traversable Wormhole: Universal Quench Dynamics in Random Spin Models
Tian-Gang Zhou, Lei Pan, Yu Chen +2
Understanding strongly interacting quantum matter and quantum gravity are both important open issues in theoretical physics, and the holographic duality between quantum field theor…
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…
