Ultrafast spectroscopy and manipulation of coupled electronic/lattice orders (B08)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 422213477

The project will use femtosecond real-time approaches to study collective modes and their nonlinear couplings in selected systems with orders resulting from strong electron-lattice coupling. The project will focus on the evolution of couplings across the rich phase diagrams by tuning pressure(strain) and temperature, focusing on the vicinities of critical points. Near the phase boundaries between different, nearly degenerate ground states, we aim to utilize nonequilibrium pathways to generate metastable states with novel functionalities which cannot be reached through thermodynamical pathways.
