Entanglement Randomness and Gapped Itinerant Carriers in a Frustrated Quantum Magnet
Luke Pritchard Cairns, Yuanqi Lyu, Chunxiao Liu +4
The quantum spin liquid (QSL) is a state manifesting extraordinary many-body entanglement, and the material NaYbSe is thought to be one of the most promising candidates for its…

Crystallography, Group Cohomology, and Lieb-Schultz-Mattis Constraints
Chunxiao Liu, Weicheng Ye
We present a computational study of the mod-2 cohomology of three-dimensional (3D) space groups, with an eye toward their applications in Lieb--Schultz--Mattis constraints. We prov…

Universality classes for purification in nonunitary quantum processes
Andrea De Luca, Chunxiao Liu, Adam Nahum +1
We consider universal aspects of two problems: (i) the slow purification of a large number of qubits by repeated quantum measurements, and (ii) the singular value structure of a pr…
