Abstract

We theoretically investigate the T-B phase diagram of cuprates building on the SU(2) pseudogap order recently obtained from the spin-fermion model. At low temperatures, our analysis reveals an almost temperature-independent critical magnetic field Bco at which d-wave superconductivity switches to a phase of charge order. For temperatures beyond a certain value of the order of the zero-field superconducting transition temperature Tc, the critical field Bco(T) sharply grows. We compare our results derived within the effective SU(2) nonlinear σ model with the phase diagram recently obtained by sound velocity measurements by LeBoeuf et al. [Nat. Phys. 9, 79 (2013)].
