Semi-analytic Evaluation of 1, 2 and 3-Electron Coulomb Integrals with Gaussian expansion of Distance Operators W= RR, Rr, rr
Sandor Kristyan
The equations derived help to evaluate semi-analytically (mostly for k=1,2 or 3) the important Coulomb integrals Int rho(r1)...rho(rk) W(r1,...,rk) dr1...drk, where the one-electro…
Quasi-linear buildup of Coulomb integrals via the coupling strength parameter in the non-relativistic electronic Schrodinger equation
Sandor Kristyan
The non-relativistic electronic Hamiltonian, Hkin + Hne + aHee, is linear in coupling strength parameter (a), but its eigenvalues (electronic energies) have only quasi-linear depen…
Optimizing single Slater determinant for Electronic Hamiltonian with Lagrange multipliers and Newton-Raphson methods as an alternative to ground state calculations via Hartree-Fock self consistent field
Sandor Kristyan
Considering the emblematic Hartree-Fock (HF) energy expression with single Slater determinant and the ortho-normal molecular orbits (MO) in it, expressed as a linear combination (L…
Nonadiabatic dynamics and multiphoton resonances in strong field molecular ionization with few cycle laser pulses
Vincent Tagliamonti, Péter Sándor, Arthur Zhao +3
We study strong field molecular ionization using few- (four to ten) cycle laser pulses. Employing a supercontinuum light source, we are able to tune the optical laser wavelength (p…
Strong Field Molecular Ionization in the Impulsive Limit: Freezing Vibrations with Short Pulses
Péter Sándor, Vincent Tagliamonti, Arthur Zhao +4
We study strong-field molecular ionization as a function of pulse duration. Experimental measurements of the photoelectron yield for a number of molecules reveal competition betwee…
Electric Transition Dipole Moment in pre-Born-Oppenheimer Molecular Structure Theory
Benjamin Simmen, Edit Matyus, Markus Reiher
This paper presents the calculation of the electric transition dipole moment in a pre-Born-Oppenheimer framework. Electrons and nuclei are treated equally in terms of the parametri…
