Pole skipping from universal hydrodynamics of (1+1)d QFTs
Richard A. Davison, Hanzhi Jiang
(1+1)d QFTs provide a tractable arena for understanding the emergence of hydrodynamics in thermal states. At high temperatures this process is governed by the weak breaking of conf…
Time Evolution of Multi-Party Entanglement Signals
Vijay Balasubramanian, Hanzhi Jiang, Simon F. Ross
We study the real-time dynamics of multi-party entanglement signals in chaotic quantum many-body systems including but not necessarily restricted to holographic conformal field the…
Islands, Double Holography, and the Entanglement Membrane
Hanzhi Jiang, Mike Blake, Anthony P. Thompson
The quantum extremal island rule allows us to compute the Page curves of Hawking radiation in semi-classical gravity. In this work, we study the connection between these calculatio…
The entanglement membrane in 2d CFT: reflected entropy, RG flow, and information velocity
Hanzhi Jiang, Márk Mezei, Julio Virrueta
The time evolution of entanglement entropy in generic chaotic many-body systems has an effective description in terms of a minimal membrane, characterised by a tension function. Fo…
New horizons for inhomogeneous quenches and Floquet CFT
Hanzhi Jiang, Márk Mezei
A fruitful avenue in investigating out-of-equilibrium quantum many-body systems is to abruptly change their Hamiltonian and study the subsequent evolution of their quantum state. I…
