Super-extended nanofiber-guided field for coherent interaction with hot atoms
نویسندگان
چکیده
We fabricate an extremely thin optical fiber that supports a super-extended mode with diameter as large 13 times the wavelength, residing almost entirely outside and guided over thousands of wavelengths (5 mm), to couple light warm atomic vapor. This unique configuration balances between strong confinement, evident by saturation powers low tens nW, long interaction thermal atoms, thereby enabling fast coherent interactions. demonstrate narrow resonances (tens MHz) electromagnetically induced transparency for signals at single-photon level relaxation (10 ns) atoms excited mode. The dimensions mode’s evanescent field are compatible Rydberg blockade mechanism, making this platform particularly suitable observing quantum nonlinear optics phenomena.

Coherent interaction of femtosecond extreme-UV light with He atoms
We show experimentally that spectral phase manipulation of ultra-short extreme-UV light pulses can induce and control coherent transient excitation of the He(1s3p) excited state by the nonresonant components of the broadband EUV light. The spectral phase manipulation of the 15th harmonic of an intense 805 nm, 80 fs pulse is achieved by propagation of the EUV light through a variable optical den...

Title of thesis: TRANSMISSION SPECTRA OF RB ATOMS NEAR AN OPTICAL NANOFIBER. Burkley Delesdernier Patterson, Master of Science, 2016 Dissertation directed by: Professor Luis A. Orozco Department of Physics We present measurements of the transmission spectra of Rb atoms at 780 nm in the vicinity of a nanofiber. A uniform distribution of fixed atoms around a nanofiber should produce a spectrum th...
متن کاملHot Spacetimes for Cold Atoms
Building on our earlier work and that of Son, we construct string theory duals of nonrelativistic critical phenomena at finite temperature and density. Concretely, we find black hole solutions of type IIB supergravity whose asymptotic geometries realize the Schrödinger group as isometries. We then identify the non-relativistic conformal field theories to which they are dual. We analyze the ther...
متن کاملCoherence properties of nanofiber-trapped cesium atoms.
We experimentally study the ground state coherence properties of cesium atoms in a nanofiber-based two-color dipole trap, localized ∼ 200 nm away from the fiber surface. Using microwave radiation to coherently drive the clock transition, we record Ramsey fringes as well as spin echo signals and infer a reversible dephasing time of T(2)(*) = 0.6 ms and an irreversible dephasing time of T(2)(') =...
متن کاملA coherent quantum annealer with Rydberg atoms
There is a significant ongoing effort in realizing quantum annealing with different physical platforms. The challenge is to achieve a fully programmable quantum device featuring coherent adiabatic quantum dynamics. Here we show that combining the well-developed quantum simulation toolbox for Rydberg atoms with the recently proposed Lechner-Hauke-Zoller (LHZ) architecture allows one to build a p...
