In this study, the time-dependent Schrodinger equation is solved using coherent states as basis sets to investigate high harmonic generation in a one-dimensional realistic system. The static coherent states (SCS) method is applied to study HHG in the hydrogen molecular ion induced by a linearly polarized laser field. The results suggest that the SCS method can be effectively used for full-dimensional quantum simulation of higher dimensional systems.
We solve the time-dependent Schrodinger equation using the coherent states as basis sets for computing high harmonic generation (HHG) in a full-dimensional single-electron realistic system. We apply the static coherent states (SCS) method to investigate HHG in the hydrogen molecular ion induced by a linearly polarized laser field. We show that SCS gives reasonable agreement compared to the three dimensional unitary split-operator approach. Next, we study isolated attosecond pulse generation in H2+. To do so, we employ the well-known polarization gating technique, which combines two delayed counter-rotating circular laser pulses, and opens up a gate at the central portion of the superposed pulse. Our results suggest that the SCS method can be used for full-dimensional quantum simulation of higher dimensional systems such as the hydrogen molecule in the presence of an external laser field.
