Coherent probing of excited quantum dot states in an interferometer.
Measurements of elastic and inelastic cotunneling currents are presented on a two-terminal Aharonov-Bohm interferometer with a Coulomb-blockaded quantum dot embedded in each arm. Coherent current contributions, even in a magnetic field, are found in the nonlinear regime of inelastic cotunneling at a finite-bias voltage. The phase of the Aharonov-Bohm oscillations in the current exhibits phase j...
متن کاملCalculation of atomic number states
We analyse the conditions for producing atomic number states in a one-dimensional optical box using the Bethe ansatz method. This approach provides a general framework, enabling the study of number state production over a wide range of realistic experimental parameters.

متن کاملPrecision Rotation Measurements with an Atom Interferometer Gyroscope
Matter-wave interferometry has the potential to be an extremely sensitive probe for inertial forces. For example, neutron interferometers have been used to measure the rotation of the Earth [1] and the acceleration due to gravity [2]. More recently, atom interference techniques have been used in demonstration experiments to measure rotations [3] and accelerations [4]. In this Letter, we present...
متن کاملObservation of saturation of fidelity decay with an atom interferometer.
We use an atom interferometer to investigate the dynamics of matter waves in a periodically pulsed optical standing wave: an atom optics realization of the quantum kicked rotor that exhibits chaotic classical dynamics. We experimentally show that a measure of the coherence between the interferometer diffraction orders can revive after a quick initial loss, and can approach a finite asymptote as...
متن کاملAtomic number fluctuations in a falling cold atom cloud
We evaluate the effective number of atoms in experiments where a probe laser beam with a Gaussian transverse profile passes through an atomic medium consisting in a cold atom cloud released from a magnetooptical trap. Considering the case where the initial distribution is a Gaussian function of position and of velocity, we give a quantitative description of the temporal variation of the effecti...
