Symmetry-based perturbation theory for electronic structure calculations
Hiromichi Nishimura, Nam Nguyen, Tanvi Gujarati +1
We develop a multi-reference perturbation theory for electronic structure calculations based on symmetries of the Hamiltonian. The reference Hamiltonian in the symmetry-based pertu…
Dynamical structure factor of one-dimensional hard rods
M. Motta, E. Vitali, M. Rossi +2
The zero-temperature dynamical structure factor of one-dimensional hard rods is computed using state-of-the-art quantum Monte Carlo and analytic continuation techniques, c…
Roton excitations and the fluid-solid phase transition in superfluid 2D Yukawa Bosons
S. Molinelli, D. E. Galli, L. Reatto +1
We compute several ground state properties and the dynamical structure factor of a 0-temperature system of Bosons interacting with the 2D screened Coulomb (2D-SC) potential. We res…
Imaginary Time Correlations and the phaseless Auxiliary Field Quantum Monte Carlo
M. Motta, D. E. Galli, S. Moroni +1
The phaseless Auxiliary Field Quantum Monte Carlo method provides a well established approximation scheme for accurate calculations of ground state energies of many-fermions system…
