Quantum criticality at strong randomness: a lesson from anomaly (opens in new tab)

arXiv:2602.02648v1 Announce Type: new Abstract: Quantum criticality in the presence of strong quenched randomness remains a challenging topic in modern condensed matter theory. We show that the topology and anomaly associated with average symmetry can be used to predict certain nontrivial universal properties. Our focus is on systems subject to average Lieb--Schultz--Mattis constraints, where lattice translation symmetry is preserved only on average, while on-site symmetries remain exact. We...
