A microfabricated atomic clock
Svenja Knappe,Vishal Shah,Peter D. D. Schwindt,Leo W. Hollberg,John Kitching,Li-Anne Liew,John M. Moreland +6 more
TL;DR: In this paper, the core physics assembly of an atomic clock is used to reduce the size and operating power of the core assembly of the atomic clock, and a volume of 9.5mm3, a fractional frequency instability of 2.5×10−10 at 1s of integration, and dissipating less than 75mW of power.
Journal ArticleDOI
Chip-scale atomic magnetometer
Peter D. D. Schwindt,Svenja Knappe,Vishal Shah,Leo W. Hollberg,John Kitching,Li-Anne Liew,John M. Moreland +6 more
TL;DR: In this paper, a small low-power magnetic sensor based on alkali atoms was constructed, which uses a coherent population trapping resonance to probe the interaction of the atoms' magnetic moment with a magnetic field, and detects changes in the magnetic flux density with a sensitivity of 50pTHz−1∕2 at 10Hz.
Journal ArticleDOI
Microfabricated alkali atom vapor cells
TL;DR: In this paper, the fabrication of chip-sized alkali atom vapor cells using silicon micromachining and anodic bonding technology is described, which may find use in highly miniaturized atomic frequency references or magnetometers.
Journal ArticleDOI
Electron tunneling experiments using Nb‐Sn ‘‘break’’ junctions
TL;DR: In this paper, an Nb-Sn filament mounted on a flexible glass beam can be broken to form an electron tunneling junction between the fracture elements, which can be continuously adjusted by varying the surface bending strain of the beam.
Chip scale atomic devices
