Control of competing phases in correlated electron systems out of equilibrium

Femtosecond laser technology has opened the possibility to probe and control the dynamics of complex condensed matter phases on ultra-short timescales. Non-equilibrium Green's functions and non-equilibrium dynamical mean-field theory provide a versatile approach to study those out of equilibrium states in correlated matter from a microscopic perspective. In this talk, I will focus on the fundamental question how long-range electronic order, such as magnetic and orbital order or superconductivity, can be manipulated, enhanced, or even induced out of equilibrium. A particular focus is put on systems with more than one competing phase: I will show how a strong non-equilibrium current can suppress charge order in favour of superconductivity, and I will discuss the dynamics in systems with intertwined spin and orbital order, which can be driven towards thermodynamically hidden states by short laser pulses.
