    "abstract": "We study one-dimensional (1D) and two-dimensional (2D) Helium atoms using a\nnew time-dependent quantum Monte Carlo (TDQMC) method. The TDQMC method employs\nrandom walkers, with a separate guiding wave attached to each walker. The\nground state is calculated by a self-consistent solution of complex-time\nSchroedinger equations for the guiding waves and of equations for the velocity\nfields of the walkers. Our results show that the many-body wavefunction and the\nground state energy of the model atoms are very close to those predicted by the\nstandard diffusion quantum Monte Carlo method. The obtained ground state can\nfurther be used to examine correlated time-dependent processes which include,\nfor example, interaction of atoms and molecules with external electromagnetic\nfields.",
