Superconductivity from the condensation of topological defects in a quantum spin-Hall insulator

Deconfined quantum critical points separate two phases with different broken symmetries, which puts them beyond the standard Landau theory of phase transitions. Here the authors present a model with a monopole-free deconfined quantum critical point, making it more amenable to detailed numerical stud...

Sumario:Deconfined quantum critical points separate two phases with different broken symmetries, which puts them beyond the standard Landau theory of phase transitions. Here the authors present a model with a monopole-free deconfined quantum critical point, making it more amenable to detailed numerical studies.
