We reveal here that the effect of thermal disorder, which decreases the condensate phase coherence at equilibrium, can be dynamically contrasted by photoexcitation with ultrashort mid-infrared pulses. In particular, our findings reveal that light pulses with photon energy comparable to the amplitude of the superconducting gap and polarized in plane along the copper-copper direction [110] can dynamically enh","authors_text":"Aandrea Damascelli, Adolfo Avella, Alexandre Marciniak, Daniele Fausti, Fabio Boschini, Francesca Giusti, Francesco Randi, Giorgia Sparapassi, H.
