DESCRIPTION:We develop a theory for light-induced superconductivity in unde
 rdoped cuprates in which the competing bond-density wave order is suppress
 ed by driving phonons with light. Close to a bond-density wave instability
  in a system with a small Fermi surface\, such as a fractionalized Fermi l
 iquid\, we show that the coupling of electrons to phonons is strongly enha
 nced at the bond-density wave ordering wavevectors\, leading to a strong s
 oftening of phonons at these wavevectors. For a model of classical phonons
  with anharmonic couplings\, we show that thecombination of strong softeni
 ng and driving can lead to large phonon oscillations. When coupled to a ph
 enomenological model describing the competition between bond-density wave 
 order and superconductivity\, these phonon oscillations melt bond-density 
 wave order\, thereby enhancing pairing correlations.\nSpeaker: Andreas Ebe
