Landau ordering phase transitions beyond the Landau paradigm
Zhen Bi, Ethan Lake, T. Senthil
Abstract
This work demonstrates the breakdown of the Landau paradigm - a standard symmetry breaking quantum phase transition can also admit new critical theories expressed in terms of a deconfined gauge theory coupled with massless Dirac fermions instead of the fluctuating order parameters.
