"Transient Dynamics of Strongly Correlated Electrons After Sudden Excitations"

Presented by Marco Schiro, Institut de Physique Theorique (IPhT), CEA, Saclay, France

Friday, January 13, 2017, 1:30 pm — Seminar Room 2nd Floor Bldg 734

The development of pump-probe spectroscopies with femtosecond time resolution, which allows to track the dynamics of electronic degrees of freedom in solids under optical excitations, opens up a new window to understand strongly correlated materials and offers the intriguing possibility of controlling their properties with light, on ultra-fast time scales. Triggered by these advances, the interest around time dependent phenomena in quantum many body systems has recently substantially grown. In this talk will review recent progress in understanding transient dynamics of electrons in correlated metals, Mott Insulators and superconductors. I will show that quite generically these systems display very sharp dynamical transitions as a function of the external perturbation, in correspondence of which the lattice response and the sensitivity to density inhomogeneities can be greatly enhanced.
