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…
Electron-pair densities with time-dependent quantum Monte-Carlo
Ivan P. Christov
In this paper we use sets of de Broglie-Bohm trajectories to describe the quantum correlation effects which take place between the electrons in helium atom due to exchange and Coul…
Time-dependent quantum Monte Carlo and the stochastic quantization
Ivan P. Christov
We examine the relation between the recently proposed time-dependent quantum Monte Carlo (TDQMC) method and the principles of stochastic quantization. In both TDQMC and stochastic…
Quantum trajectory perspective of atom-field interaction in attosecond time scale
Ivan P. Christov
Here the ionization and high harmonic generation in Hydrogen and Helium by using quantum (hydrodynamic) trajectories is analyzed theoretically. The quantum trajectories allow a sel…
