Blue-detuned optical ring trap for Bose-Einstein condensates based on conical refraction
A. Turpin, J. Polo, Yu. V. Loiko +6
We present a novel approach for the optical manipulation of neutral atoms in annular light structures produced by the phenomenon of conical refraction occurring in biaxial optical…
Coherent injecting, extracting, and velocity filtering of neutral atoms in a ring trap via spatial adiabatic passage
Yurii Loiko, Veronica Ahufinger, Ricard Menchon-Enrich +2
We introduce here a coherent technique to inject, extract, and velocity filter neutral atoms in a ring trap coupled via tunneling to two additional waveguides. By adiabatically fol…
Spatial adiabatic passage processes in sonic crystals with linear defects
Ricard Menchon-Enrich, Jordi Mompart, Veronica Ahufinger
We investigate spatial adiabatic passage processes for sound waves propagation in sonic crystals, consisting of steel cylinders embedded in a water host medium, that present two li…
Tunneling-induced angular momentum for single cold atoms
Ricard Menchon-Enrich, Suzanne McEndoo, Jordi Mompart +2
We study the generation of angular momentum carrying states for a single cold particle by breaking the symmetry of a spatial adiabatic passage process in a two-dimensional system c…
Single-atom interferometer based on two-dimensional spatial adiabatic passage
Ricard Menchon-Enrich, Suzanne McEndoo, Thomas Busch +2
In this work we propose a novel single-atom interferometer based on a fully two-dimensional spatial adiabatic passage process using a system of three identical harmonic traps in a…
