Polaritonic modes in a dense cloud of atoms
, 2015 We analyze resonant light scattering by an atomic cloud in a regime where near-field interactions between scatterers cannot be neglected. We first use a microscopic approach and calculate numerically the eigenmodes of the cloud for many different ...

Atomic Parity Non-Conservation, Neutron Radii, and Effective Field Theories of Nuclei [PDF]
, 2005 Accurately calibrated effective field theories are used to compute atomic parity non-conserving (APNC) observables. Although accurately calibrated, these effective field theories predict a large spread in the neutron skin of heavy nuclei.

Resonance fluorescence in a band gap material: Direct numerical simulation of non-Markovian evolution [PDF]
, 2000 A numerical method of calculating the non-Markovian evolution of a driven atom radiating into a structured continuum is developed. The formal solution for the atomic reduced density matrix is written as a Markovian algorithm by introducing a set of ...

A benign, low Z electron capture agent for negative ion TPCs [PDF]
, 2009 We have identified nitromethane (CH$_3$NO$_2$) as an effective electron capture agent for negative ion TPCs (NITPCs). We present drift velocity and longitudinal diffusion measurements for negative ion gas mixtures using nitromethane as the capture ...
