Driving Order: Theory of Ultrafast Dynamics in Superconductors

Understanding the collective motion of electrons in solids and their interplay with lattice vibrations is a central goal of condensed matter physics. Time-domain spectroscopies with tailored laser pulses offer novel ways to manipulate emergent ordering phenomena in superconductors or charge-density waves. Here I will show recent progress in the theoretical description of ultrafast dynamics in superconductors. Motivated by experiments that control electrons via resonant driving of the crystal lattice, I will show how light-enhanced superconductivity plays out in the time domain. In the second part, I will show preliminary results regarding laser control of competing superconducting and charge-density wave states.
