Abstract
Utilizing time-evolution techniques in (infinite) matrix-product-state representation, we study the non-equilibrium dynamics of driven Mott insulators and demonstrate photoinduced $\eta$ pairing directly in the thermodynamic limit. Analyzing the time evolution of the corresponding pairing correlations, we determine the optimal laser pump parameters for which long-range $\eta$-pairing becomes dominant after pulse irradiation. The time-dependent photoemission spectra for this optimal pump parameter set show clear signatures of the photoinduced insulator-to-metal phase transition related to the formation of $\eta$ pairs.
Author comments upon resubmission
Dear Editor,
Herewith, we resubmit the revised version of our manuscript.
We thank the Referee for pointing out the typos. In the revised version, we have corrected them. Regarding the double occupancy n_d, we have added its definition and a note "n_d(t=0)>0 for finite U values considered" on page 3.
Yours sincerely,
Satoshi Ejima and Holger Fehske
