Correlated electron dynamics with time-dependent quantum Monte Carlo: three-dimensional helium
Ivan P. Christov
Here the recently proposed time-dependent quantum Monte Carlo method is applied to three dimensional para- and ortho-helium atoms subjected to an external electromagnetic field wit…

Polynomial-time-scaling quantum dynamics with time-dependent quantum Monte Carlo
Ivan P. Christov
Here we study the dynamics of many-body quantum systems using time dependent quantum Monte Carlo method where the evolution is described by ensembles of particles and guide waves.…

Molecular dynamics with time dependent quantum Monte Carlo
Ivan P. Christov
In this paper we propose an ab initio method to solve quantum many-body problems of molecular dynamics where both the electronic and the nuclear degrees are represented by ensemble…
