Optical spectroscopy of a microsized Rb vapour sample in magnetic fields up to 58 tesla

, 2017
We use a magnetometer probe based on the Zeeman shift of the rubidium resonant optical transition to explore the atomic magnetic response for a wide range of field values.

A highly stable atomic vector magnetometer based on free spin precession

, 2015
We present a magnetometer based on optically pumped Cs atoms that measures the magnitude and direction of a 1 $\mu$T magnetic field. Multiple circularly polarized laser beams were used to probe the free spin precession of the Cs atoms.

Broadband dark matter axion detection using a cylindrical capacitor

Nuclear Physics B
Cosmological axions/axion-like particles can compose a significant part of dark matter; however, the uncertainty of their mass is large. Here, we propose to search the axions using a cylindrical capacitor, in which the static electric field converts dark

Comments on the measurement of power spectra of the interplanetary magnetic field [PDF]

Examination of possible noise sources in the measurement of the power spectrum of fluctuations in the interplanetary magnetic field shows that most measurements by fluxgate magnetometers are limited by digitization noise whereas the search coil ...

Hall effect magnetometer [PDF]

, 1974
A magnetometer which uses a single crystal of bismuth selenide is described. The rhombohedral crystal structure of the sensing element is analyzed. The method of construction of the magnetometer is discussed.

A large-scale magnetic shield with 10^6 damping at mHz frequencies

, 2015
We present a magnetically shielded environment with a damping factor larger than one million at the mHz frequency regime and an extremely low field and gradient over an extended volume.

Security of GPS/INS based On-road Location Tracking Systems

, 2018
Location information is critical to a wide-variety of navigation and tracking applications. Today, GPS is the de-facto outdoor localization system but has been shown to be vulnerable to signal spoofing attacks.
