Optical bistability in a -type atomic system including near dipole-dipole interaction
Juan D. Serna, Amitabh Joshi
The advantage of optical bistability (OB) using three-level electromagnetically induced transparency (EIT) atomic system over the two-level system is its controllability, as absorp…
Absorption-dispersion in a three-level electromagnetically induced transparency medium including near dipole-dipole interaction effects
Amitabh Joshi, Juan D. Serna
Dynamical evolution and electromagnetically induced transparency (EIT) is investigated here in a three-level -type atomic system including near-dipole-dipole interaction among a…
Noise-induced quantum coherence in photosynthetic complexes with multiple energy transfer pathways
Dmitri V. Voronine, Konstantin E. Dorfman, Bin Cao +1
We theoretically investigate exciton relaxation dynamics in molecular aggregates based on model photosynthetic complexes under various conditions of incoherent excitation. We show…
Facile residue analysis of recent and prehistoric cook-stones using handheld Raman spectrometry
Laura Short, Alston V. Thoms, Bin Cao +5
We performed food residue analysis of cook-stones from experimental and prehistoric earth ovens using a handheld Raman spectrometry. Progress in modern optical technology provides…
Modeling a nanocantilever based biosensor using a stochastically perturbed harmonic oscillator
Patrick Snyder, Amitabh Joshi, Juan D. Serna
Nanoscale biosensors are devices designed to detect analytes by combining biological components and physicochemical detectors. One of the well known methods of constructing these s…
Refractive index of a transparent liquid measured with a concave mirror
Amitabh Joshi, Juan D. Serna
This paper describes the spherical concave mirror method for measuring the index of refraction of transparent liquids. We derived the refractive index equation using Snell's law an…
