DQMP Seminar - Towards non-thermal control of quantum materials

08.12.2020 13:00 – 14:00

Quantum matter has become an umbrella term for materials displaying complex emergent phenomena. In these compounds, the intricate interplay of spin, charge, lattice and orbital degrees of freedom gives rise to competing and coexisting phases, which are easily tunable by external perturbations. As such, quantum materials are an ideal platform to explore future technological applications [1]. Recently, the use of intense ultrafast light pulses to modify of quantum matter has emerged as a pathway towards functionality based on new out-of-equilibrium phenomena [2].

In this talk, I will discuss how discovering ways to control quantum matter has allowed us to test fundamental concepts of strongly correlated materials [3], provide answers to long standing questions of cuprate phenomenology [4] and revealed new phenomena without equilibrium counterpart [5]. I will also describe the next directions and research opportunities that I have identified in the field of ultrafast control of quantum matter.
