Towards a magnetic centrifuge decelerator for beyond Standard Model physics searches.

ORAL

Abstract

Ultracold atoms or molecules offer a quantum metrology platform with enhanced sensitivity to Beyond Standard Model physics. Current production techniques of ultracold species rely on laser deceleration or ultracold assembly techniques, which limits the available species for these experiments. Here we present a method to slow any magnetic atom or molecule to a standstill using a magnetic centrifuge decelerator. The decelerator consists of a spiral-shaped rotating magnetic guide, which provides a centrifugal potential hill to the incoming particles, applying a decelerating force. With a suitable choice of rotational speed and spiral radius, the method is generally applicable to any magnetic species. This method promises to expand the class of trappable atoms and molecules substantially and offers new opportunities in a broad range of experiments.
