Fiske-amplified superfluid interferometry

چکیده
We report an experimental demonstration of signal amplification for a superfluid He interferometer by allowing the matter waves from two Josephson mass current sources to interact with the resonances within the experimental cell. We characterize the interferometer using an external phase shift and demonstrate a 30-fold enhancement in intrinsic phase sensitivity. We also demonstrate a truly continuous operation of this interference device.

Superfluid quantum interference in multiple-turn reciprocal geometry.
We report the observation of superfluid quantum interference in a compact, large-area matter-wave interferometer consisting of a multiple-turn interfering path in reciprocal geometry. Utilizing the Sagnac effect from Earth's rotation in conjunction with a phase shifter made of superfluid heat current, we demonstrate that such a scheme can be extended for sensitive rotation sensing as well as fo...
متن کاملObservation of an extrinsic critical velocity using matter wave interferometry
We report an experiment that uses a superfluid helium quantum interference device to probe the initial onset of the motion of a single vortex line driven by axial flow in a macroscopic channel. When the superfluid velocity reaches a temperature independent critical value !vc#1 mm/s" periodic 2! phase slippage occurs with a frequency of the order of a few Hz. As the axial flow velocity increases...
متن کاملCoherence Properties of a Bose-Einstein Condensate in an Optical Superlattice
We study the effect of a one dimensional optical superlattice on the superfluid fraction, number squeezing, dynamic structure factor and the quasi-momentum distribution of the Mott-insulator. We show that due to the secondary lattice,there is a decrease in the superfluid fraction and the number fluctuation. The dynamic structure factor which can be measured by Bragg spectroscopy is also suppres...
متن کاملDirect measurement of the critical velocity above which a tuning fork generates turbulence in superfluid helium
The dynamics of an electrically-driven 8 kHz quartz tuning fork has been studied experimentally in liquid helium-4 in the temperature range 1.3< T < 4.2K under the saturated vapour pressure. The fork has relatively large dimensions compared to standard 32 kHz fork used in recent investigations. The velocity of the tip of the fork prong is measured by the indirect electromechanical equivalent me...
متن کاملColorimetric method for detecting amplified nucleic acids.
Methods for detecting and measuring the success of nucleic acid sequence amplifications can be developed by detecting the by-products of amplification procedures. One method includes the detection of inorganic phosphate (Pi) during or on completion of the PCR. The method requires modification of assay conditions to prevent thermal- and template-independent enzymatic activity from nonspecificall...
