Measurement of Correlated Multiple Light Scattering in Utracold Atomic 85Rb

Determination of Interfacial Area in Gas-Liquid Two Phase by Light Transmission

The purpose of the present paper is to develop light beam method to measurement of interfacial area in a rectangular gas-liquid bubble column. Total interfacial area can be determined in bubble column filled by transparent liquid by light transmission method. According to pervious researches, the fraction of parallel light is function of interfacial area and optical path l...

Spontaneous dissociation of long-range Feshbach molecules.

We study the spontaneous dissociation of diatomic molecules produced in cold atomic gases via magnetically tunable Feshbach resonances. We provide a universal formula for the lifetime of these molecules that relates their decay to the scattering length and the loss rate constant for inelastic spin relaxation. Our universal treatment as well as our exact coupled channels calculations for 85Rb di...

Slowing of 85Rb atoms with isotropic light.

Towards Measurement of Polarization Properties of Skin using the Ellipsometry Technique

Introduction: The human skin is an active medium from the optical point of view. Therefore, the diagnostic and therapeutic techniques employing light are increasing. Current optical techniques are based on the measurement of the intensity of reflected absorbed or backscattered light from or within skin. Studies have shown that biological tissues, and in particular skin, demonstrate polarization...

Sympathetic cooling of 85 Rb and 87 Rb

We demonstrate sympathetic cooling between magnetically trapped 85Rb and 87Rb atoms. Up to 6!106 85Rb atoms are cooled via elastic collisions with a reservoir of 8!108 87Rb atoms. The temperature of the binary atomic ensemble is adjusted by using radio-frequency evaporation of 87Rb. Temperatures as low as T "100 nK have been realized in the binary ensemble. Through a cross-dimensional mixing ap...
