Coherent and Incoherent Time-Resolved Diffuse Scattering Intensity from First Principles
Matteo Furci, Giovanni Marini, Stefano Mocatti +1
Time-resolved diffuse scattering from X-ray free-electron lasers and ultrafast electron diffraction gives access to the nonequilibrium lattice dynamics of photoexcited solids in re…
Light-Induced Transient Polarization Reversal in Rhombohedrally Stacked Bilayer Transition Metal Dichalcogenides via an Electronic Mechanism
Xiangzhou Zhu, Stefano Mocatti, Matteo Calandra
Light-induced sliding ferroelectricity in two-dimensional van der Waals materials enables polarization control via relative layer motion. However, polarization switching occurs on…
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…
Wannier interpolation of reciprocal-space periodic and non-periodic matrix elements in the optimally smooth subspace
Giulio Volpato, Stefano Mocatti, Giovanni Marini +1
Maximally localized Wannier functions use the gauge freedom of Bloch wavefunctions to define the optimally smooth subspace with matrix elements that depend smoothly on crystal mome…
Light-Induced Nonthermal Phase Transition to the Topological Crystalline Insulator State in SnSe
Stefano Mocatti, Giovanni Marini, Matteo Calandra
Femtosecond pulses have been used to reveal hidden broken symmetry states and induce transitions to metastable states. However, these states are mostly transient and disappear afte…
