Exponential propagators for the Schrodinger equation with a time-dependent potential
AIP Publishing (2018-06)We consider the numerical integration of the Schrödinger equation with a time-dependent Hamiltonian given as the sum of the kinetic energy and a time-dependent potential. Commutator-free (CF) propagators are exponential ... -
Symplectic time-average propagators for the Schrodinger equation with a time-dependent Hamiltonian
AIP Publishing (2017-03)Several symplectic splitting methods of orders four and six are presented for the step-by-step time numerical integration of the Schrödinger equation when the Hamiltonian is a general explicitly time-dependent real operator. ...
