Spin dynamics in atomically-precise nanostructures (B05)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 328545488

This project aims at resolving and understanding ultrafast dynamics of excited spin and correlated states at the atomic scale. We have set up a source of terahertz pulses and optical pulses and coupled them into a low-temperature scanning tunneling microscope. Using this technique, we will investigate the spin dynamics of single atoms and magnetic nanostructures on surfaces and resolve the influence of spin-orbit coupling and exchange interactions with the local environment (work package 1). Furthermore, we will investigate the dynamics of optically and electronically excited states in highly correlated systems, such as Kondo lattices and spin liquids (work package 2). Our results are expected to give valuable insights into relaxation channels of excited spin states and their time scales. This knowledge is indispensable for the manipulation and coherent control of spin states at the atomic scale.
