DOI: 10.1007/s10773-024-05678-9
Abstract: It is known that the ensemble of random pure quantum states, constructed by bipartite maximally entangled states and random unitary matrices generated according to the Haar measure, exhibits an average entanglement entropy that obeys an… read more here.

DOI: 10.1103/physrevlett.127.060602
Abstract: Eigenstate thermalization in quantum many-body systems implies that eigenstates at high energy are similar to random vectors. Identifying systems where at least some eigenstates are nonthermal is an outstanding question. In this Letter we show… read more here.

DOI: 10.1103/physrevlett.134.180402
Abstract: Chirality is a property of a gapped phase of matter in two spatial dimensions that can be manifested through nonzero thermal or electrical Hall conductance. In this Letter, we prove two no-go theorems that forbid… read more here.

DOI: 10.1103/r8mr-zbx1
Abstract: Dynamical quantum systems both driven by unitary evolutions and monitored through measurements have proved to be fertile ground for exploring new dynamical quantum matters. While the entanglement structure and symmetry properties of monitored systems have… read more here.
