η–paired hidden phase in photodoped Mott insulators — •Jiajun Li1, Denis Golez2, Philipp Werner3, and Martin Eckstein11University of Erlangen-Nuremberg, Germany — 2Flatiron Institute, New York, US — 3University of Fribourg, Switzerland

We show that a metastable η–pairing superconducting phase can be induced by photodoping doublons and holes into a strongly repulsive fermionic Hubbard model. The doublon-hole condensate extends over a wide range of doublon densities and effective temperatures. Different non-equilibrium protocols to realize this state are proposed and numerically tested. We also study the optical conductivity in the superconducting phase, which exhibits ideal metallic behavior, i.e., a delta function at zero-frequency in the conductivity, in conjunction with negative conductivity at large frequencies. These characteristic optical properties can provide a fingerprint of the η-pairing phase in pump-probe experiments.
