A scalable optical detection scheme for matter wave interferometry
نویسندگان
چکیده
Imaging of surface adsorbed molecules is investigated as a novel detection method for matter wave interferometry with fluorescent particles. Mechanically magnified fluorescence imaging turns out to be an excellent tool for recording quantum interference patterns. It has a good sensitivity and yields patterns of high visibility. The spatial resolution of this technique is only determined by the Talbot gratings and can exceed the optical resolution limit by an order of magnitude. A unique advantage of this approach is its scalability: for certain classes of nanosized objects, the detection sensitivity will even increase significantly with increasing size of the particle.

Detecting Topological Defect Dark Matter Using Coherent Laser Ranging System
In the last few decades, optical frequency combs with high intensity, broad optical bandwidth, and directly traceable discrete wavelengths have triggered rapid developments in distance metrology. However, optical frequency combs to date have been limited to determine the absolute distance to an object (such as satellite missions). We propose a scheme for the detection of topological defect dark...
متن کاملOptical polarizabilities of large molecules measured in near-field interferometry
We discuss a novel application of matter wave interferometry to characterize the scalar optical polarizability of molecules at 532nm. The interferometer presented here consists of two material absorptive gratings and one central optical phase grating. The interaction of the molecules with the standing light wave is determined by the optical dipole force and is therefore directly dependent on th...
متن کاملFrequency-modulated light scattering interferometry employed for optical properties and dynamics studies of turbid media
In the present work, fiber-based frequency-modulated light scattering interferometry (FMLSI) is developed and employed for studies of optical properties and dynamics in liquid phantoms made from Intralipid(®). The fiber-based FMLSI system retrieves the optical properties by examining the intensity fluctuations through the turbid medium in a heterodyne detection scheme using a continuous-wave fr...
متن کاملQuantum carpet interferometry for trapped atomic Bose-Einstein condensates
We propose an “interferometric” scheme for Bose-Einstein condensates using near-field diffraction. The scheme is based on the phenomenon of intermode traces or quantum carpets; we show how it may be used in the detection of weak forces. Typeset using REVTEX 1 One of the most important aspects of the study of Bose-Einstein Condensates (BEC’s) in dilute trapped alkali gases has been the developme...
متن کاملAtomic entanglement generation and detection via degenerate four-wave mixing of a Bose-Einstein condensate in an optical lattice
The unequivocal detection of entanglement between two distinct matter-wave pulses is a significant challenge that has yet to be experimentally demonstrated. We describe a realistic scheme to generate and detect continuous-variable entanglement between two atomic matter-wave pulses produced via degenerate four-wave mixing from an initially trapped Bose-Einstein condensate loaded into a one-dimen...
