Abstract

Excitons play an essential role in the optical response of two-dimensional materials. These are bound states due to correlations in many-body systems and are conceived as quasiparticles formed by an electron and a hole. We develop a numerical approach to simulate the electron dynamics induced by laser pulse interactions. The real-time simulations enable us to simulate the coherent dynamics of excitons and calculate the observables that can be measured in ultrafast experiments currently available in HHG laser-based laboratories. An exciting venue is the modeling of the interaction of attosecond pulses with 2D materials and the manipulation of excitons in valleytronics schemes. These simulations allow us to explore ultrafast electronics and valleytronics adding time as a control knob and exploiting electron coherence at the early times of excitation.
