One-dimensional array of ion chains coupled to an optical cavity
New Journal of Physics, 2013 We present a novel system where an optical cavity is integrated with a microfabricated planar-electrode ion trap. The trap electrodes produce a tunable periodic potential allowing the trapping of up to 50 separate ion chains aligned with the cavity and ...

Optical Ferris Wheel for Ultracold Atoms [PDF]
Conference on Coherence and Quantum Optics, 2007 We propose a versatile optical ring lattice suitable for trapping cold and quantum degenerate atomic samples at discrete angular positions. We demonstrate the realisation of intensity patterns generated from Laguerre-Gauss ($\exp(i \ell )$) modes with different $\ell$ indices.

Recombination of Three Ultracold Fermionic Atoms [PDF]
Physical Review Letters, 2003 Three-body recombination of identical, spin-polarized fermionic atoms in the ultracold limit is investigated. The mechanisms for recombination are described in terms of the ``scattering volume'' $V_p$ in the framework of the adiabatic hyperspherical representation.

Vibrational Mode Multiplexing of Ultracold Atoms [PDF]
Physical Review Letters, 2013 Sending multiple messages on qubits encoded in different vibrational modes of cold atoms or ions along a transmission waveguide requires to merge first and then separate the modes at input and output ends. Similarly, different qubits can be stored in the modes of a trap and be separated later.

Nonlinear localized modes in one-dimensional nanoscale dark-state optical lattices
Nanophotonics, 2022 Optical lattices (OLs) with conventional spatial periodic λ/2, formed by interfering the counterpropagating laser beams with wavelength λ, are versatile tools to study the dynamical and static properties of ultracold atoms. OLs with subwavelength spatial

A scalable quantum computing platform using symmetric-top molecules
New Journal of Physics, 2019 We propose a new scalable platform for quantum computing (QC)—an array of optically trapped symmetric-top molecules (STMs) of the alkaline earth monomethoxide (MOCH _3 ) family.

Magnetic conveyor belt transport of ultracold atoms to a superconducting atomchip
, 2014 We report the realization of a robust magnetic transport scheme to bring 3x10^8 ultracold 87Rb atoms into a cryostat. The sequence starts with standard laser cooling and trapping of 87Rb atoms, transporting first horizontally and then vertically through ...

Ring trap for ultracold atoms [PDF]
Physical Review A, 2006 We propose a new kind of toroidal trap, designed for ultracold atoms. It relies on a combination of a magnetic trap for rf-dressed atoms, which creates a bubble-like trap, and a standing wave of light. This new trap is well suited for investigating questions of low dimensionality in a ring potential.

Microwave quantum logic spectroscopy and control of molecular ions
New Journal of Physics, 2013 A general method for rotational microwave spectroscopy and control of polar molecular ions via direct microwave addressing is considered. Our method makes use of spatially varying ac Stark shifts, induced by far off-resonant, focused laser beams to ...
