The refractive index n is one of the most important materials parameters solids and, in recent years, has become subject significant interdisciplinary interest, especially nanostructures and meta-materials. It is, principle, a macroscopic quantity, so its meaning on length scale few nanometers, i.e., well below wavelength light, not clear priori related to methods measurement this scale. Here we introduce novel experimental approach for mapping effective local value n∼ solid films analysis...
We suggest a novel approach for spatially resolved probing of local fluctuations the refractive index n in solids by means single-molecule (SM) spectroscopy. It is based on dependence T1(n) effective radiative lifetime T1 dye centres due to local-field effects. Detection SM zero-phonon lines at low temperatures gives values natural spectral linewidth (which inversely proportional T1) and makes it possible reveal distribution solids. Here we demonstrate this possibility example amorphous...
Himangshu Prabal Goswami opened the discussion of paper by Jörg Wrachtrup: When you describe Hamiltonian, coupling between ancillary and sensor spin is g sample Ji. Are these frequency dependent? If not, what quantitative ra
We consider the influence of near dipole–dipole interaction, underlying local field, on dynamics two-level and V-type three-level atoms exposed to cw-laser radiation. The interaction between is shown give rise Poincaré–Andronov–Hopf bifurcation in steady-state solution equations motion. As a result, populations energy levels periodically vary time. In framework nondegenerate model, dynamical instabilities are proved be impossible.
We report the discovery of a GeV-associated phenomenon which is strong (up to an order) stochastic reversible enhancements photoluminescence intensity in single GeV diamond synthesized with high-pressure, high-temperature technique. were lucky observe this effect only one crystal among dozens similar microdiamonds. Each rise and fall above its stable moderate level may be referred as superflare smooth dynamics transients develop on timescale seconds. These flares tend recur infinitely at...
A many particle quantum-kinetic formalism is suggested to derive the Maxwell-Bloch-type equations which describe interaction of quantum emitters with light in a frozen dielectric. It shown that can meet concept local variations dielectric properties and their influence on emitter. The definitions response effective refractive index macroscopically homogeneous media are discussed.
