Worldsheet patching, 1-form symmetries, and "Landau-star" phase transitions
Pablo Serna, Andrés M. Somoza, Adam Nahum
The analysis of phase transitions of gauge theories has relied heavily on simplifications that arise at the boundaries of phase diagrams, where certain excitations are forbidden. T…

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…
