A local description of strong symmetries and strong-to-weak symmetry breaking in quantum many-body systems
Ruizhi Liu, Jinmin Yi, Dominic V. Else
In mixed states of quantum systems, symmetries come in two types: strong and weak. Furthermore, it has been argued that in quantum many-body systems, strong symmetries can be "spon…
In search of diabolical critical points
Naren Manjunath, Dominic V. Else
A phase transition is an example of a ``topological defect'' in the space of parameters of a quantum or classical many-body systems. In this paper, we consider phase diagram topolo…
Topological Phases of Many-Body Localized Systems: Beyond Eigenstate Order
David M. Long, Dominic V. Else
Many-body localization (MBL) lends remarkable robustness to nonequilibrium phases of matter. Such phases can show topological and symmetry breaking order in their ground and excite…
Anomalies of global symmetries on the lattice
Yi-Ting Tu, David M. Long, Dominic V. Else
't Hooft anomalies of global symmetries play a fundamental role in quantum many-body systems and quantum field theory (QFT). In this paper, we make a systematic analysis of lattice…
't Hooft anomalies in metals
Dominic V. Else
I review some recent results on understanding the physics of metals in an exact non-perturbative way through the powerful field-theoretic concepts of emergent symmetries and 't Hoo…
