Diffusive Relaxation of Participation Entropy in U(1)-symmetric Dynamics
Hanchen Liu, Tianci Zhou, Xiao Chen
Participation entropy (PE) quantifies the spread of a many-body wavefunction across configuration space. While PE relaxes rapidly in generic chaotic systems, we show that $\mathrm{…
Low Rank Structure of the Reduced Transition Matrix
Cathy Li, Bruno Bertini, Katja Klobas +1
The influence-matrix formalism provides an alternative route to the classical simulation of quantum dynamics. Because influence matrices retain information only about the effective…
An efficient algorithm to compute entanglement in states with low magic
ChunJun Cao, Gong Cheng, Tianci Zhou
A bottleneck for analyzing the interplay between magic and entanglement is the computation of these quantities in highly entangled quantum many-body magic states. Efficient extract…
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…
A Physical Theory of Two-stage Thermalization
Cheryne Jonay, Tianci Zhou
One indication of thermalization time is subsystem entanglement reaching thermal values. Recent studies on local quantum circuits reveal two exponential stages with decay rates $r_…
