Optimization of the ionization time of an atom with tailored laser pulses: a theoretical study
David Kammerlander, Alberto Castro, Miguel A. L. Marques
How fast can a laser pulse ionize an atom? We address this question by considering pulses that carry a fixed time-integrated energy per-area, and finding those that achieve the dou…
Speeding up the solution of the Bethe-Salpeter equation by a double-grid method and Wannier interpolation
David Kammerlander, Silvana Botti, Miguel A. L. Marques +2
The Bethe-Salpeter equation is a widely used approach to describe optical excitations in bulk semiconductors. It leads to spectra that are in very good agreement with experiment, b…
Band structures of Cu2nSnS4 and Cu2nSnSe4 from many-body methods
Silvana Botti, David Kammerlander, Miguel A. L. Marque
We calculate the band structures of kesterite and stannite Cu2ZnSnS4 and Cu2ZnSnSe4, using a state-of-the-art self-consistent GW approach. Our accurate quasiparticle states allow t…
Optimal Control of the Electronic Current Density - An application to one- and two-dimensional one-electron systems
David Kammerlander, Alberto Castro, Miguel A. L. Marques
Quantum optimal control theory is a powerful tool for engineering quantum systems subject to external fields such as the ones created by intense lasers. The formulation relies on a…
Semiconductor quantum tubes: dielectric modulation and excitonic response
David Kammerlander, Filippo Troiani, Guido Goldoni
We study theoretically the optical properties of quantum tubes, one-dimensional semiconductor nanostructures where electrons and holes are confined to a cylindrical shell. In these…
Biexciton stability in carbon nanotubes
David Kammerlander, Deborah Prezzi, Guido Goldoni +2
We have applied the quantum Monte Carlo method and tight-binding modelling to calculate the binding energy of biexcitons in semiconductor carbon nanotubes for a wide range of diame…
