Senior Staff Scientist

Michael Först

Michael is engaged in the non-equilibrium control of electronic and magnetic order in complex materials through nonlinear phononics. This type of ultrafast structural control makes use of the anharmonic response of the crystal lattice to the resonant excitation of phonons by intense mid-infrared and terahertz light fields. Michael’s activities involve table-top nonlinear optical spectroscopies, time-resolved x-ray diffraction at free electron lasers, as well as the development of novel multi-terahertz pulse generation schemes.

Staff Scientists

Michele Buzzi

Michele’s research mainly focuses on the optical control of superconductivity using intense mid-infrared pulses. Although his general interests involve driven states in quantum materials, he is specifically interested in organic molecular solids, where excitation of local molecular vibrations can directly modify the electronic interaction parameters and cause the appearance of exotic non-equilibrium states. To investigate these driven states, Michele develops and uses table-top ultrafast spectroscopic techniques to track the changes in materials’ properties induced upon photoexcitation.

Michael Fechner

Michael’s research explores the interactions and dynamics within multifunctional materials using computational methods. In particular, he focuses on materials that exhibit a complex interplay of structure, charge and spin degrees of freedom. The aim of his research is to develop formalisms that explain and describe light induced materials properties.

Daniele Nicoletti

Daniele’s research focuses on the study of nonequilibrium superconducting states driven by optical stimulation at infrared and terahertz frequencies. He is primarily working on high-TC cuprates and organic molecular superconductors, but his interests extend, more generally, to the optically-driven nonlinear dynamics in complex solids. To this end, he is combining a variety of spectroscopies and pump-probe techniques with the use of external pressure and strong magnetic fields.

Eryin Wang

Eryin’s research focuses on utilizing on-chip ultrafast transport technique to study the electrical transport properties of different light-induced transient phases, which remain so far largely unexplored. In the past, he connected MBE-grown K3C60 thin film to photo-conductive switches with coplanar waveguide to probe the critical current behavior of light-induced superconducting state in K3C60. To this end, he is extending the ultrafast transport technique to the nonlinear region and to other light-induced phenomena.

He is primarily focused on studying cuprate superconductors, but his interests extend to the wide variety of phases in quantum materials.
