SUMMARY:Dynamical Materials Control with Light
DESCRIPTION:Featuring Wanzheng Hu\, Max Planck Institute for the Structure 
	and Dynamics of Matter\n\nPart of the Biophysics/Condensed Matter Seminar S
	eries.\n\nUsing ultra-short laser pulses to drive quantum materials out of 
	equilibrium is an emergent technique for dynamical materials control. On th
	e one hand\, unfolding quantum phases in time offers new perspective in und
	erstanding fundamental physics. On the other hand\, selectively driving low
	-energy excitations using femtosecond laser pulses can achieve novel quantu
	m phases inaccessible at equilibrium.\nCombining dynamical light control wi
	th ultra-broadband transient optical spectroscopy\, we are able to directly
	 probe the dynamics of lattice vibrations and electronic excitations over t
	he whole far-infrared region\, revealing the physics behind the transient q
	uantum phases. In this talk\, I will present two examples: 1) transient sup
	erconductivity in multi-layer cuprate superconductors\, and 2) phonon-drive
	n insulator-to-metal transition in nickelate heterostructures.
