TMDC quantum dots in ultrashort optical pulse

We theoretically study transition metal decalcogenide quantum dot high harmonic generation in the field of ultrashort optical pulse. The electron dynamics in such strong pulse is irreversible and after the pulse the electron system resides in highly excited states with a finite dipole moment. Highly nonlinear electron dynamics during the pulse generates the high harmonics of large intensity. We analyze numerically how the intensities of such high harmonics depend on the amplitude of the pulse and the size of the quantum dot.
