Optical Levitation of Arrays of Microspheres
Benjamin Siegel, Gadi Afek, Cecily Lowe +4
Levitated optomechanical systems are rapidly becoming leading tools for precision sensing of forces and accelerations acting on particles in the femtogram to nanogram mass range. T…
Scalable architecture for trapped-ion quantum computing using RF traps and dynamic optical potentials
David Schwerdt, Lee Peleg, Yotam Shapira +9
Qubits based on ions trapped in linear radio-frequency traps form a successful platform for quantum computing, due to their high fidelity of operations, all-to-all connectivity and…
Coherent scattering of low mass dark matter from optically trapped sensors
Gadi Afek, Daniel Carney, David C. Moore
We propose a search for low mass dark matter particles through momentum recoils caused by their scattering from trapped, nm-scale objects. Our projections show that even with a mod…
Control and measurement of electric dipole moments in levitated optomechanics
Gadi Afek, Fernando Monteiro, Benjamin Siegel +5
Levitated optomechanical systems are rapidly becoming leading tools for precision sensing, enabling a high level of control over the sensor's center of mass motion, rotation and el…
Anomalous statistics of laser-cooled atoms in dissipative optical lattices
Gadi Afek, Nir Davidson, David A. Kessler +1
Diffusion occurs in numerous physical systems throughout nature, drawing its generality from the universality of the central limit theorem. Around a century ago it was realized tha…
Limits on the abundance of millicharged particles bound to matter
Gadi Afek, Fernando Monteiro, Jiaxiang Wang +3
Millicharged particles (mCPs) are hypothesized particles possessing an electric charge that is a fraction of the charge of the electron. We report a search for mCPs with charges $\…
Mechanical Quantum Sensing in the Search for Dark Matter
Daniel Carney, Gordan Krnjaic, David C. Moore +32
Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matt…
Search for composite dark matter with optically levitated sensors
Fernando Monteiro, Gadi Afek, Daniel Carney +3
Results are reported from a search for a class of composite dark matter models with feeble, long-range interactions with normal matter. We search for impulses arising from passing…
Force and acceleration sensing with optically levitated nanogram masses at microkelvin temperatures
Fernando Monteiro, Wenqiang Li, Gadi Afek +3
This paper demonstrates cooling of the center-of-mass motion of 10 m-diameter optically levitated silica spheres to an effective temperature of K, achieved by minimiz…
Deviations from generalized Equipartition in Confined, Laser Cooled Atoms
Gadi Afek, Alexander Cheplev, Arnaud Courvoisier +1
We observe a significant steady-state deviation from the generalized equipartition theorem, one of the pivotal results of classical statistical mechanics, in a system of confined,…
Revival of Raman Coherence of Trapped Atoms
Gadi Afek, Jonathan Coslovsky, Alexander Mil +1
We perform Raman spectroscopy of optically trapped non interacting \Rb atoms, and observe revivals of the atomic coherence at integer multiples of the trap period. The effect of co…
Producing an Efficient, Collimated and Thin Annular Beam with a Binary Axicon
Oz Livneh, Gadi Afek, Nir Davidson
We propose and demonstrate a method to produce a thin and highly collimated annular beam that propagates similarly to an ideal thin Gaussian ring beam, maintaining its excellent pr…
Spectroscopic Measurement of the Softness of Ultra-Cold Atomic Collisions
Jonathan Coslovsky, Gadi Afek, Alexander Mil +2
The softness of elastic atomic collisions, defined as the average number of collisions each atom undergoes until its energy decorrelates significantly, can have a considerable effe…
Observing Power-Law Dynamics of Position-Velocity Correlation in Anomalous Diffusion
Gadi Afek, Jonathan Coslovsky, Arnaud Courvoisier +2
In this letter we present a measurement of the phase-space density distribution (PSDD) of ultra-cold \Rb atoms performing 1D anomalous diffusion. The PSDD is imaged using a direct…
