Anisotropic dynamical reconstruction of quantum geometry in quenched Chern insulators
Nan Li, Zhiyong Liu, Zhaoxin Liang +1
Under unitary dynamics, the Chern number of an evolving quantum state remains conserved even when a quench drives the Hamiltonian across a topological phase transition. In sharp co…

From flat to narrow bands: Engineering quantum emission in a one-dimensional Lieb lattice
Zhiyong Liu, Yue Sun, Ying Hu
We develop a comprehensive theoretical framework that unifies quantum emission dynamics in one-dimensional Lieb lattices, bridging the gap between ideal flat-band coherence and rea…
