Quantum control and measurement of atomic spins in
The nonlinearity is thought to result from alteration to the hyperfine-shift interaction due to temporary van der Waals molecules formed between alkali-metal and buffer-gas atoms. We investigate... alkali atoms) and also single-photon transitions (with alkaline earth-like atoms). The interferometers shown in Fig 1.1(b) take advantage of single-photon transitions (as opposed to traditional Raman transitions) because using light pulses from one dir ection at a time allows for

Hunter immortal invisible god only wise lyrics pdf detection scheme that suppresses inhomogeneous light shifts and keeps the interferometer operating in a balanced mode that minimizes technical noise. We show that when the atoms interact with two-frequency light

Ultra Cold Atoms Using Laser Light T. K. Subramaniam Department of Science and (BEC) in dilute gases of alkali atoms, and for early fundamental studies of the properties of the condensates. In evaporative cooling the hottest atoms in a sample are allowed to escape which reduces the average temperature of the sample. Ultra cold atoms are also used in experiments for precision … the youth criminal justice act pdf The one-photon Raman light shift is the differential light shift that the out-of-resonance Raman lasers imprint onto the two hyperﬁne states in the Raman-type interferometers.

light shift suppression in conformity with the closed-form analytic solutions. The computational studies have The computational studies have also been extended to investigate RR interference for a Doppler-broadened vapor medium.
- Abstract Quantitative formulas for computing the light shift due to virtual transitions in any alkali atom are presented. The theoretically calculated light shifts for Rb 87 are compared with experimentally measured light shifts, and good quantitative agreement is obtained.
- alkali-metal atoms is monitored using either transmission of the pumping light through the cell or by Faraday rotation of a weak diode laser s,5mWd tuned slightly off the Rb D2
- small vector light shift on individual 87Rb atoms trapped in sites of an optical lattice, we show that we can eliminate the dependence of the clock transition frequency on the intensity
- We report a novel method of measuring the spin polarization of alkali-metal atoms by detecting the NMR frequency shifts of noble gases. We calculated the profile of 87Rb D1 line absorption cross sections. We then measured the absorption profile of the sample cell, from which we calculated the 87Rb number densities at different temperatures.
