Quantum many-body systems and their application for quantum technologies
In the Quantum Dynamics Unit, we explore many-particle quantum systems, in particular their intercation with electromagnetic radiation, to discover new quantum phenomena and, where applicable, harness them for quantum technologies. Electrons on liquid helium provide an excellent experimental platform to investigate quantum many-body physics and explore new exotic states of matter. Our current work is focused on novel photo-transport phenomena, collective coupling of electron ensembles to cavity modes, electron crystals, as well as spin resonance and potential application of electrons for spin qubits. Coupled electron-nuclear spin ensembles in some crystalline solids, such as easy-plane antiferromagnets, is another system of interest to us. Also, we investigate impurity spins in diamond for use as quantum memories, microwave-optical photon quantum transducers, and other hybrid quantum systems.
Congratulations to Jiabao for defending his thesis entitled "Coherent control of charged particle systems with microwave photons" in front of two tough theoreticians!
