Photoinduced phase heterogeneity and charge localization in SnSe
Benjamin J. Dringoli, Stefano Mocatti, Giovanni Marini +4
Time-resolved multi-terahertz (THz) spectroscopy is used to observe pump fluence-dependent dynamics in the optical conductivity of photoexcited tin selenide (SnSe) over an ultrabro…
Nonequilibrium Photocarrier and Phonon Dynamics from First Principles: a Unified Treatment of Carrier-Carrier, Carrier-Phonon, and Phonon-Phonon Scattering
Stefano Mocatti, Giovanni Marini, Giulio Volpato +2
We develop a first-principles many-body framework to describe the dynamics of photocarriers and phonons in semiconductors following ultrafast excitation. Our approach incorporates…
First-order phase transition driven by competing charge-order fluctuations in 1T'-TaTe
S. K. Mahatha, A. Kar, J. Corral-Sertal +20
First-order phase transitions, characterized by a discontinuous change in the order parameter, are intriguing phenomena in condensed matter physics. However, the underlying, materi…
Nonthermal magnetization pathways in photoexcited semiconductors
Giovanni Marini
The stabilization of long-range magnetic order in nominally non-magnetic semi-conductors using femtosecond light pulses is an exciting yet experimentally challenging goal. Theoreti…
