Seed II: Ultrafast Dynamics of Low Energy Excitations in Frustrated Materials @ Massachusetts Institute of Technology
Nuh Gedik, Assistant Professor, Department of Physics
The goal of this seed project is to understand the emergent macroscopic properties of magnetically frustrated materials by studying the dynamics of their low energy excitations and phase transitions with the use of novel time resolved techniques. In these experiments, the material is excited by an ultrashort laser pulse and the recovery of the resulting state back to the ground state is probed with femtosecond temporal and sub-Angstrom spatial resolutions. The PI has developed different methods to selectively generate and probe charge, spin or lattice excitations in quantum materials. The information that will be obtained from these measurements will help us to understand the properties of the ground state (i.e. test whether a spin liquid behavior is realized), low energy excitations and phase diagram.
