Three Hamiltonians are Sufficient for Unitary -Design in Temporal Ensemble
Yi-Neng Zhou, Tian-Gang Zhou, Julian Sonner
Unitary -designs are central to quantum information and quantum many-body physics, as they provide efficient proxies for Haar-random dynamics. We study how chaotic Hamiltonian e…
Critical behaviors of magic and participation entropy at measurement induced phase transitions
Eliot Heinrich, Hanchen Liu, Tianci Zhou +1
We study the participation and stabilizer entropy of non-unitary quantum circuit dynamics, focusing on the critical line that separates the low-entanglement spin-glass phase and th…
Magic transition in monitored free fermion dynamics
Cheng Wang, Zhi-Cheng Yang, Tianci Zhou +1
We investigate magic and its connection to entanglement in 1+1 dimensional random free fermion circuits, with a focus on hybrid free fermion dynamics that can exhibit an entangleme…
Error-resilient Reversal of Quantum Chaotic Dynamics Enabled by Scramblons
Yu-Chen Li, Tian-Gang Zhou, Shengyu Zhang +8
The emergence of the arrow of time in quantum many-body systems stems from the inherent tendency of Hamiltonian evolution to scramble quantum information and increase entanglement.…
Emergent Universal Quench Dynamics in Randomly Interacting Spin Models
Yuchen Li, Tian-Gang Zhou, Ze Wu +9
Universality often emerges in low-energy equilibrium physics of quantum many-body systems, despite their microscopic complexity and variety. Recently, there has been a growing inte…
Scrambling Transition in Free Fermion Systems Induced by a Single Impurity
Qucheng Gao, Tianci Zhou, Pengfei Zhang +1
In quantum many-body systems, interactions play a crucial role in the emergence of information scrambling. When particles interact throughout the system, the entanglement between t…
