We demonstrate detection of a weak alternate-current magnetic field by application the spin echo technique to F = 2 Bose-Einstein condensates. A sensitivity 12 pT/Hz^1/2 is attained with atom number 5*10^3 at spatial resolution 99 \mu m^2. Our observations indicate fluctuations synchronous power supply line frequency. show that this noise greatly suppressed reverse phase field. useful in order create stable environment, which an important requirement for atomic experiments require bias
Abstract We propose a method to measure the electron electric dipole moment (eEDM) using ultracold entangled francium (Fr) atoms trapped in an optical lattice, yielding uncertainty below standard quantum limit. Among alkali atoms, Fr offers largest enhancement factor eEDM. With based experiment, sensing states could enable search for eEDM at level 10 −30 e cm. estimate statistical and systematic errors attached proposed measurement scheme on this technique. A successful of exploration new...
