A Review of Contemporary Atomic Frequency Standards
Bonnie L. Schmittberger, David R. Scherer
Atomic frequency standards are used to generate accurate and precise time and frequency, enabling many communications, synchronization, and navigation systems in modern life. GPS a…
Analysis of Short-Term Stability of Miniature 171Yb+ Buffer Gas Cooled Trapped Ion Clock
David R. Scherer, C. Daniel Boschen, Jay Noble +5
We demonstrate an improvement in short-term stability by a factor of 10 over a previous generation miniature buffer gas cooled trapped ion clock. We describe the enhancement to det…
Progress on a Miniature Cold-Atom Frequency Standard
David R. Scherer, Robert Lutwak, Mark Mescher +8
Atomic clocks play a crucial role in timekeeping, communications, and navigation systems. Recent efforts enabled by heterogeneous MEMS integration have led to the commercial introd…
Characterization of Alkali Metal Dispensers and Non-Evaporable Getter Pumps in Ultra-High Vacuum Systems for Cold Atomic Sensors
David R. Scherer, David B. Fenner, Joel M. Hensley
A glass ultrahigh vacuum chamber with rubidium alkali metal dispensers and non-evaporable getter pumps has been developed and used to create a cold atomic sample in a chamber that…
Spontaneous vortices in the formation of Bose-Einstein condensates
C. N. Weiler, T. W. Neely, D. R. Scherer +3
Phase transitions are ubiquitous in nature, ranging from protein folding and denaturisation, to the superconductor-insulator quantum phase transition, to the decoupling of forces i…
Vortex Formation by Merging and Interference of Multiple Trapped Bose-Einstein Condensates
David R. Scherer
An apparatus for producing atomic-gas Bose-Einstein condensates (BECs) of 87-Rb atoms is described. The apparatus produces 87-Rb BECs in a dual-chamber vacuum system that incorpora…
