Published in 2023 at "Physical Chemistry Chemical Physics"

DOI: 10.1039/d3cp01429k

Abstract: The dynamics and kinetics of spin-forbidden transitions between N(2D) and N(4S) via collisions with N2 molecules are investigated using a quantum wave packet (WP) method and the semi-classical coherent switches with decay of mixing (CSDM)… read more here.

Published in 2019 at "Progress of Theoretical and Experimental Physics"

DOI: 10.1093/ptep/ptz144

Abstract: Nambu mechanics is a generalized Hamiltonian dynamics characterized by an extended phase space and multiple Hamiltonians. In a previous paper [Prog. Theor. Exp. Phys. 2013, 073A01 (2013)] we revealed that the Nambu mechanical structure is… read more here.

Published in 2024 at "Physical Review A"

DOI: 10.1103/physreva.110.013706

Abstract: We present a time-dependent variational approach with the multiple Davydov $D_2$ trial state to simulate the dynamics of light-matter systems when the field is in a coherent state with an arbitrary finite mean photon number.… read more here.

Published in 2018 at "Atoms"

DOI: 10.3390/atoms6020020

Abstract: We present in this paper the results of a theoretical study of electron impact broadening for several lines of the Ar VII ion. The results have been obtained using our quantum mechanical method and the… read more here.
