Optical protection of alkali-metal atoms from spin relaxation
Avraham Berrebi, Mark Dikopoltsev, Ori Katz +1
We present an optical technique for suppressing relaxation in alkali-metal spins using a single off-resonant laser beam. The method harnesses a physical mechanism that synchronizes…
Faraday-Ramsey rotation measurement in a thin cell as an analogy to an atomic beam
Mark Dikopoltsev, Eliran Talker, Yefim Barash +2
Atomic beams are powerful tools for measuring spin coherence in hot vapors but require bulky setups, limiting device miniaturization. We demonstrate that micron-thin vapor cells ca…
Magnetic-field-independent spin-exchange relaxation-free magnetometer
Mark Dikopoltsev, Uriel Levy, Or Katz
SERF magnetometers based on dense ensembles of alkali-metal spins are precision quantum sensors that hold the record of measured and projected sensitivity to magnetic fields, in th…
Suppressing the Decoherence of Alkali-Metal Spins at Low Magnetic Fields
Mark Dikopoltsev, Avraham Berrebi, Uriel Levy +1
Interactions of electron spins with rotational degrees of freedom during collisions or with external fields are fundamental processes that limit the coherence time of spin gases. W…
