Ultrafast laser pulses can redistribute charges in Mott insulators on extremely short time scales, leading to the fast generation of photocarriers. It has recently been demonstrated that these photocarriers can form a novel $\eta$--paired condensate at low temperatures, featuring a staggered superconducting pairing field. In this conference paper, we discuss the origin of the $\eta$--paired hidden phase and its optical response which may be detected in a pump-probe experiment. The hidden phase…

Entropy-cooled nonequilibrium states of the Hubbard model
We show that the recently proposed cooling-by-doping mechanism allows to efficiently prepare interesting nonequilibrium states of the Hubbard model. Using nonequilibrium dynamical mean field theory
Heating-Induced Long-Range η Pairing in the Hubbard Model.
TLDR
It is shown how, upon heating the spin degrees of freedom of the Hubbard model to infinite temperature, the symmetries of the system allow the creation of steady states with long-range correlations between η pairs, which are a subset of the steady states described in Yang's seminal Letter.
Light-induced evaporative cooling of holes in the Hubbard model
TLDR
This work demonstrates the emergence of antiferromagnetic order in a system which is initially in a weakly correlated state above the maximum Néel temperature and suggests a general strategy for inducing strong correlation phenomena in periodically modulated atomic gases in optical lattices or light-driven materials.

Photoinduced η Pairing in the Hubbard Model.
TLDR
This finding demonstrates that nonequilibrium many-body dynamics is an alternative pathway to access a new exotic quantum state that is absent in the ground-state phase diagram, and also provides an alternative mechanism for enhancing superconductivity.
