Weighted Time Averages and Weak Convergence to Equilibrium in Quantum Integrable Systems
Xinyu Liu
This paper establishes a natural quantum counterpart of weak equilibration for statistical ensembles in integrable systems. For quantum systems with pure point spectrum, single-tim…

Inhomogeneous Quantum Quenches of Conformal Field Theory with Boundaries
Xinyu Liu, Alexander McDonald, Tokiro Numasawa +2
We develop a method to calculate generic time-dependent correlation functions for inhomogeneous quantum quenches in (1+1)-dimensional conformal field theory (CFT) induced by sudden…

Two-dimensional quantum breakdown model with Krylov subspace many-body localization
Xinyu Liu, Biao Lian
We propose a two-dimensional (2d) quantum breakdown model of hardcore bosons interacting with disordered spins which would be classical without the bosons. It resembles particles i…
