Optimization of Operation Parameters in a Cesium Atomic Fountain Clock Using Monte Carlo Method
IEEE Access, 2021 Number of detected atoms and contrast of Ramsey fringe are critical operation parameters in an atomic fountain clock. To optimize these operation parameters, a Monte Carlo method is utilized to simulate the evolution of the atomic cloud. It is found that

Analysis of the Kondo effect in ferromagnetic atomic-sized contacts [PDF]
, 2012 Atomic contacts made of ferromagnetic metals present zero-bias anomalies in the differential conductance due to the Kondo effect. These systems provide a unique opportunity to perform a statistical analysis of the Kondo parameters in nanostructures since

Valence and Atomic Number [PDF]
Linguistic Inquiry, 2011 The semantic basis and morphosyntactic reflexes of Kiowa-Tanoan noun classification are perspicuously captured in a system with three bivalent number features: [±singular], [±augmented], [±group]. Privative analyses of the same facts require, inter alia, features without semantic motivation, syntactic mechanisms that violate Inclusivity, and feature ...

Atom number calibration in absorption imaging at very small atom numbers
Open Physics, 2012 Abstract Cold atom experiments often use images of the atom clouds as their exclusive source of experimental information. The most commonly used technique is absorption imaging, which provides accurate information about the shapes of the atom clouds, but requires care when seeking the absolute atom number for small atom samples.
