Senior Staff Scientist

Michael Först

M Foerst

Michael investigates nonlinear phononics in the solid state. The goal of this research is the full control of ultrafast lattice-driven phase transitions in correlated electron systems, such as light-induced superconductivity in high-TC cuprates and magnetic switching in manganites and nickelates. Michael’s research involves ultrafast hard and soft X-ray diffraction at the Stanford LCLS free electron lasers, as well as ultrafast optical spectroscopy. He also works on the generation and shaping of high-intensity phase-stable femtosecond pulses at mid-infrared wavelengths.

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 Nicoletti

Daniele studies the coherent control of complex materials using strong laser fields at Terahertz frequencies. He is mainly performing experiments on the control of superconductivity in high-Tc cuprates and organic molecular solids, but his interests extend more generally to the coherently excited many-body dynamics in strongly-correlated systems. He is combining the use of intense Terahertz pump pulses (generated with both table-top sources and Free-Electron Lasers) with different probing techniques, including time-resolved THz spectroscopy and femtosecond X-ray diffraction.

Alice Cantaluppi

Alice investigates the response of the three-dimensional organic superconductor potassium-doped fullerides to strong resonant low-energy excitations. Using strong ultrashort MIR pulses delivered by an optical parametric amplifier and broadband THz-Time domain spectroscopy setup, she studies the evolution of the transient superconducting-like response under high pressure.
