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. Bldg. 99, Rm. 02.071, Phone: -5360 |

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'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. Bldg. 99, Rm. 02.059; Phone: - 6625 |

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. Bldg. 99, Rm. 02.061, Phone: -6208 |

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.

PhD Students
Alexander investigates the nonlinear lattice dynamics in ferroelectric materials induced by resonant large-amplitude phonon excitation. The goal of this work is to coherently control the ferroelectric polarization potentially leading to its ultrafast switching.
Matthias investigates lattice driven phase transitions in complex oxides with a focus on dynamic coherent stabilization of the transient state. To this end, he is developing a high power mid-infrared source with pico- to nanosecond tunable pulse length.
Dawei investigates control of superconductivity in high-Tc cuprates under external magnetic fields using pump-probe spectroscopy in the THz regime. He is currently working on experiments on La2-xBaxCuO4 with strong-field THz pulses, aiming at probing and manipulating states in which superconductivity coexists with charge and spin order.
