Abstract: Clock transitions (CTs) in spin systems, which occur at avoided level crossings, enhance quantum coherence lifetimes T2 because the transition becomes immune to the decohering effects of magnetic field fluctuations to first order. We present… read more here.

DOI: 10.1088/1367-2630/ab3871
Abstract: We present a novel method for engineering an optical clock transition that is robust against external field fluctuations and is able to overcome limits resulting from field inhomogeneities. The technique is based on the application… read more here.

DOI: 10.1103/physrevlett.125.153201
Abstract: Permanent electric dipole moments (EDMs) of fundamental particles such as the electron are signatures of parity and time-reversal violation occurring in physics beyond the standard model. EDM measurements probe new physics at energy scales well… read more here.
