Article Synopsis
- - Ultralight bosons like axion-like particles are considered strong contenders for dark matter and can create stable structures called topological defects that cluster dark matter in small areas throughout the galaxy.
- - The study utilized a global network of optical magnetometers to search for transient signals from domain walls created by these axion-like particles.
- - After analyzing a month of data, the researchers found no significant signals, which helps to limit the theoretical possibilities of dark matter involving these particles.
A number of techniques exist to use an ensemble of atoms as a quantum memory for light. Many of these propose to use backward retrieval as a way to improve the storage and recall efficiency. We report on a demonstration of an off-resonant Raman memory that uses backward retrieval to achieve an efficiency of 65 ± 6% at a storage time of one pulse duration.
