Particle-wave dichotomy in quantum Monte Carlo: unlocking the quantum correlations
Ivan P. Christov
Here, a dichotomy of particles and waves is employed in a quantum Monte Carlo calculation of interacting electrons. Through the creation and propagation of concurrent stochastic en…
Quantum dynamics at finite temperature: Time-dependent quantum Monte Carlo study
Ivan P. Christov
In this work we investigate the ground state and the dissipative quantum dynamics of interacting charged particles in an external potential at finite temperature. The recently devi…
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…
Dynamic correlations with time dependent quantum Monte Carlo
Ivan P. Christov
In this paper, we solve quantum many-body problem by propagating ensembles of trajectories and guiding waves in physical space. We introduce the 'effective potential' correction wi…
