Control Superconductivity with Light

Abstract:

Using ultra-short laser pulses to drive quantum materials out of equilibrium is an emergent technique for dynamical materials control. Selectively driving low-energy excitations using femtosecond laser pulses can achieve novel quantum phases inaccessible at equilibrium. Combining dynamical light control with ultra-broadband transient optical spectroscopy, we are able to directly probe the dynamics of lattice vibrations and electronic excitations over the whole far-infrared region, revealing the physics behind the transient quantum phases. I will present our recent work on light-induced transient superconductivity in cuprates.
