We report the observation of replica symmetry breaking (RSB) in a weakly scattering optofluidic random laser (ORL). Coherent random lasing is indicated by the presence of narrow peaks rising out of the spectral background. This coherence helps to ide

Recent work in the development of glass-ceramic scintillators at the Georgia Tech Research Institute (GTRI) has focused on modifying formulation of the oxide host glass and scintillating crystal phase, secondary heat treatment (ceramization) schedule

In this work, we explore a novel approach to quantify and predict events related to bimolecular recognition. The theoretical framework leverages mathematics from radar signal processing and communication networks in the form of a matched filter to de

We study replica symmetry breaking (RSB) in an optofluidic random laser. Using a pump-probe technique recently developed to map the lasing modes results in RSB only at the edges of the pumped region.

We present a computational study of the pump-probe response of a single atom to assess any microscopic anisotropy induced by strong, non-resonant optical fields. Using simulations of the Schrodinger equation for an atom exposed to a linearly polarize

We propose a beam propagation method variant, which only requires the computational grid to span the core region of a waveguiding structure. Optical fields outside are accounted for through semitransparent boundary conditions. The method is fast, sim

A numerical model based on the finite-difference time-domain method is developed to simulate fluctuations which accompany the dephasing of atomic polarization and the decay of excited state's population. This model is based on the Maxwell-Bloch equat
