Two-stage relaxation of operators through domain wall and magnon dynamics
Cheryne Jonay, Cathy Li, Tianci Zhou
The out-of-time ordered correlator (OTOC) has become a popular probe for quantum information spreading and thermalization. In systems with local interactions, the OTOC defines a ch…
Operator entanglement entropy of the time evolution operator in chaotic systems
Tianci Zhou, David J. Luitz
We study the growth of the operator entanglement entropy (EE) of the time evolution operator in chaotic, many-body localized and Floquet systems. In the random field Heisenberg mod…
Entanglement Entropy of Local Operators in Quantum Lifshitz Theory
Tianci Zhou
We study the growth of entanglement entropy(EE) of local operator excitation in the quantum Lifshitz model which has dynamic exponent z = 2. Specifically, we act a local vertex ope…
Wigner translations and the observer-dependence of the position of masslesss spinning particles
Michael Stone, Vatsal Dwivedi, Tianci Zhou
The Wigner little group for massless particles is isomorphic to the Euclidean group . Applied to momentum eigenstates, or to infinite plane waves, the Euclidean "Wigne…
Berry Phase, Lorentz Covariance, and Anomalous Velocity for Dirac and Weyl Particles
Michael Stone, Vatsal Dwivedi, Tianci Zhou
We consider the relation between spin and the Berry-phase contribution to the anomalous velocity of massive and massless Dirac particles. We extend the Berry connection that depend…
