From Densities to Potentials: Benchmarking Local Exchange-Correlation Approximations
Visagan Ravindran, Clio Johnson, Neil D. Drummond +2
Using the Kohn-Sham (KS) inversion method of Hollins et al. [J. Phys.: Condens. Matter 29, 04LT01 (2017)], we invert densities from variational and diffusion quantum Monte Carlo (Q…

Quantum Monte Carlo study of low-dimensional Fermi fluids of dipolar atoms
Clio Johnson, Neil D. Drummond, James P. Hague +1
Fermionic cold atoms in optical traps provide viable quantum simulators of correlation effects in electronic systems. For dressed Rydberg atoms in two-dimensional traps with out-of…

Propagation of light in cold emitter ensembles with quantum position correlations due to static long-range dipolar interactions
G. J. Bean, N. D. Drummond, J. Ruostekoski
We analyze the scattering of light from dipolar emitters whose disordered positions exhibit correlations induced by static, long-range dipole-dipole interactions. The quantum-mecha…
