A room temperature 19-channel magnetic field mapping device for cardiac signals (2009)
Bison, G., Castagna, N., Hofer, A., Knowles, P., Kasprzak, M., ...
We present a multichannel cardiac magnetic field imaging system built in Fribourg from optical double-resonance Cs vapor magnetometers. It consists of 25 individual sensors designed to record...
Test of Lorentz invariance with spin precession of ultracold neutrons (2009)
Altarev, I., Baker, C. A., Ban, G., Bison, G., Bodek, K., Daum, M., ...
A clock comparison experiment, analyzing the ratio of spin precession frequencies of stored ultracold neutrons and $^{199}$Hg atoms is reported. %57 No daily variation of this ratio could be found,...

Altarev, I, Baker, CA, Ban, G, Bison, G, Bodek, K, Daum, M, ...
Dynamical MCG Mapping with an Atomic Vapor Magnetometer (2006)
A Weis, R Wynands, R Fenici, G Bison
We have developed a magnetometer based on magnetic resonance in cesium vapor optically pumped by resonant laser radiation, which has the sensitivity and bandwidth to record human magneto-cardiograms....
