Single atom in a superoscillatory optical trap
Hamim Mahmud Rivy, Syed A. Aljunid, Emmanuel Lassalle +2
Optical tweezers have become essential tools to manipulate atoms or molecules at a single particle level. However, using standard diffracted-limited optical systems, the transverse…
Telecom-wavelength spectra of a Rydberg state in a hot vapor
Wenfang Li, Jinjin Du, Mark Lam +1
We study telecom-wavelength spectra of a Rydberg state in an atomic vapor with a three-photon excitation scheme. Two lasers of 780 nm and 776 nm are used to pump Rubidium-85 atoms…
Bi-color atomic beam slower and magnetic field compensation for ultracold gases
Jianing Li, Kelvin Lim, Swarup Das +8
Transversely loaded bidimensional-magneto-optical-traps (2D-MOT) have been recently developed as high flux sources for cold strontium atoms to realize a new generation of compact e…
Parallel assembly of arbitrary defect-free atom arrays with a multi-tweezer algorithm
Weikun Tian, Wen Jun Wee, An Qu +4
Defect-free atom arrays are an important precursor for quantum information processing and quantum simulation. Yet, large-scale defect-free atom arrays can be challenging to realize…
Compact single-seed, module-based laser system on a transportable high-precision atomic gravimeter
Fong En Oon, Rainer Dumke
A single-seed, module-based compact laser system is demonstrated on a transportable -based high-precision atomic gravimeter. All the required laser frequencies for…
Compact active vibration isolation and tilt stabilization for a portable high-precision atomic gravimeter
Fong En Oon, Rainer Dumke
In high-precision atomic gravimeters, a rest mass is needed to provide a gravity reference, which is typically the retro-reflecting mirror of the Raman laser beams that addresses t…
