“…AT with delayed laser pulses has been demonstrated by a number of groups [5][6][7][8][9] as a method for coherently transferring population between internal atomic states and simultaneously imparting momentum to them. It relies on the atoms remaining in a dark state, a superposition of ground states which is decoupled from the excited state.…”

Abstract. We describe in detail our caesium atom interferometer which uses a combination of microwaves and momentum-changing adiabatic transfer pulses. This combination allows us to achieve spatial separation between the arms of the interferometer. We account for the observed visibility of the resulting interference fringes and find that the effects which contribute the most are optical pumping and magnetic fields.

“…With suitable modification [15][16][17][18][19][20], the technique provides a means of creating superpositions of initial and final states. Essentially the evolution is adiabatically stopped just when half of the population is transferred.…”

Preparation of nondegenerate coherent superpositions in a three-state ladder system assisted by Stark shifts

We propose a technique to prepare coherent superpositions of two nondegenerate quantum states in a three-state ladder system, driven by two simultaneous fields near resonance with an intermediate state. The technique, of potential application to enhancement of nonlinear processes, uses adiabatic passage assisted by dynamic Stark shifts induced by a third laser field. The method offers significant advantages over alternative techniques: (i) it does not require laser pulses of specific shape and duration and (ii) it requires less intense fields than schemes based on two-photon excitation with nonresonant intermediate states. We discuss possible experimental implementation for enhancement of frequency conversion in mercury atoms.

“…Since then, there have been many papers; for example, those that report Bragg's diffraction of the matter wave from the optical fields. These experiments demonstrate up to eighth order of Bragg's diffraction [17,18]. All these experiments are performed with the classical field.…”

Measurement of entangled states via atomic beam deflection in Bragg’s regime

We propose a scheme for the measurement of joint photon statistics and Wigner function of the entangled field states between two separate cavities. The scheme utilizes the momentum state of the two-level atoms in Bragg's regime. The probability of finding the atom in any one of the momentum states is the product of joint photon statistics and an oscillatory function. The argument of the function contains the information of the joint photon numbers in two cavities. We use the method of state reduction to a single set of joint photon numbers, which is a consequence of the measuring sequence. The repeated measurement of the set of photon numbers gives the joint photon statistics of the entangled field state. The complete entangled state can be reconstructed as a Wigner function from the knowledge of photon statistics of the coherently displaced entangled state.
