Efficient nonequilibrium electron dynamics from first-principles: leveraging Koopmans spectral functionals and Wannier localization

Giovanni Cistaro, Miguel Sá, Davide Sangalli +2

We present an efficient first-principles approach for simulating the nonequilibrium electron dynamics in extended systems beyond the linear regime. The method combines Koopmans-com…

Direct observation of strain and confinement shaping the hole subbands of Ge quantum wells

Enrico Della Valle, Arianna Nigro, Miki Bonacci +6

Germanium-silicon-germanium (Ge/Si $_{x}$ Ge $_{1 - x}$ ) heterostructures have emerged as a promising platform for hole-spin quantum technologies and high-mobility electronics, where st…

All-optical control of second-harmonic generation in $β$ -BaB $_{2}$ O $_{4}$ via coherent, terahertz-driven acentric lattice displacement

Flavio Giorgianni, Nicola Colonna, Gabriel Nagamine +6

Dynamical control of the nonlinear optical properties of solids -- with light itself -- will be essential for future ultrafast photonic technologies. Previously, methods to modulat…
