Velocity Rephased Longitudinal Momentum Coherences with Differentially Detuned Separated Oscillatory Fields
نویسندگان
چکیده
Localized oscillating fields are beam splitters that can entangle internal and longitudinal momentum states in an atomic beam. Differentially detuned separated oscillatory fields and an am modulator constitute a “white fringe” longitudinal interferometer which rephases velocity averaging by a process analogous to half a spin echo. Differentially detuned separated oscillatory fields are used to produce a downstream coherence or rephase an upstream coherence in an atomic beam. [S0031-9007(98)06971-3]

Longitudinal Atom Optics : Measuring the Density Matrix of a Matter Wave Beam by Richard Alan Rubenstein
This thesis describes recent developments of theoretical and experimental techniques for longitudinal atom optics and interferometry, in which time-dependent interactions are used to create coherences in the longitudinal momentum of a matter wave. We present a fully quantum mechanical treatment of the classic molecular beams resonance experiment, a beam of two state particles interacting with t...
متن کاملRb atoms in a blue-detuned dipole trap: Coherence and ground-state differential ac Stark shift
Blue-detuned dipole traps and their ability to preserve atomic coherences are interesting for precision measurement applications. In this paper, we present experimental studies on the differential ac Stark shift of the ground-state hyperfine splitting in 87Rb atoms confined in a dynamic blue-detuned dipole trap. We systematically study the power and detuning effects on the Rabi resonance freque...
متن کاملVariational Principle and Plane Wave Propagation in Thermoelastic Medium with Double Porosity Under Lord-Shulman Theory
The present study is concerned with the variational principle and plane wave propagation in double porous thermoelastic infinite medium. Lord-Shulman theory [2] of thermoelasticity with one relaxation time has been used to investigate the problem. It is found that for two dimensional model, there exists four coupled longitudinal waves namely longitudinal wave (P), longitudinal thermal wave (T),...
متن کاملRashba realization: Raman with RF.
We theoretically explore a Rashba spin-orbit coupling scheme which operates entirely in the absolute ground state manifold of an alkali atom, thereby minimizing all inelastic processes. An energy gap between ground eigenstates of the proposed coupling can be continuously opened or closed by modifying laser polarizations. Our technique uses far-detuned 'Raman' laser coupling to create the Rashba...
متن کاملIntegrable, oblique travelling waves in quasi-charge-neutral two-fluid plasmas
A Hamiltonian description of oblique travelling waves in a two-fluid, charge-neutral, electron-proton plasma reveals that the transverse momentum equations for the electron and proton fluids are exactly integrable in cases where the total transverse momentum flux integrals, P (d) y and P (d) z , are both zero in the de Hoffman Teller (dHT) frame. In this frame, the transverse electric fields ar...
