Senior Staff Scientist

Michael Först

Michael investigates nonlinear phononics in the solid state, that is the anharmonic response of the crystal lattice to resonant phonon excitation by intense mid-infrared and terahertz light pulses. His research aims to contribute to the understanding of ultrafast lattice-driven phenomena in correlated electron systems, such as insulator-metal transitions, control of magnetic order, or light-induced superconductivity in high-TC cuprates. Michael exploits ultrafast hard and soft X-ray diffraction at free electron lasers, as well as table-top ultrafast linear and nonlinear optical spectroscopy. In addition, he develops new schemes for the generation and shaping of waveform-stable intense pulses at mid-infrared and THz frequencies.

Staff Scientists

Michele Buzzi

Michele joined Andrea’s group in February 2016 on a fellowship of the Swiss National Science Foundation. He aims to investigate light-induced effects in organic superconductors by using both ultrafast x-rays techniques and ultrafast optical spectroscopic techniques under pressure.

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 induced by laser pulse 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 a variety of complex solids. To this end, he is combining a broad spectrum of pump-probe techniques with the use of high external pressures 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.

Gregor Jotzu

Originally an atomic physicist, Gregor now investigates the creation of superconducting and topologically non-trivial phases using periodic driving in solids. He is performing mid-IR pump, THz probe experiments on organic materials, applying high-pressure techniques, and extending Floquet theory to solid state systems. He is also developing a setup to measure and switch magnetic fields on sub-picosecond timescales in order to investigate the magnetic dynamics of light-induced superconductors.

Joseph joined Andrea’s group as a PhD student in 2019. His research is focused on investigating light-induced superconductivity in the alkali-doped fulleride K3C60 via ultrafast electronic transport techniques. In particular, he is developing micro-structured devices incorporating MBE-grown K3C60 thin-films with the aim to probe on a picosecond timescale the nonlinear electrical response of the photo-excited superconducting state.

Mariana’s research focuses on the study of nonequilibrium superconductivity in organic compounds with ultrafast transport techniques. Currently, she is developing microstructured devices on chip which integrate a coplanar stripline with an alkali-doped fulleride K3C60 thin film. With this technique, she can study the transport properties of the nonequilibrium superconducting state upon optical excitation in the mid infrared.
