Coherent polarization self-rotation
Roy Shaham, Orr Meron, Or Katz +2
We introduce and study coherent polarization self-rotation (CPSR), a two-photon light-matter interaction in dense alkali-metal vapors that enables both narrowband optical spectrosc…
Constraints on axion-like dark matter from a SERF comagnetometer
Itay M. Bloch, Roy Shaham, Yonit Hochberg +3
Ultralight axion-like particles are well-motivated relics that might compose the cosmological dark matter and source anomalous time-dependent magnetic fields. We report on terrestr…
Probing dipolar interactions between Rydberg atoms and ultracold polar molecules
Lingbang Zhu, Jeshurun Luke, Roy Shaham +2
We probe resonant dipolar interactions between ultracold KRb molecules and Rydberg Rb atoms in an optically trapped ensemble. Through state-selective ionizatio…
Optimal Strategies for Optical Quantum Memories Using Long-Lived Noble-Gas Spins
Or Katz, Eran Reches, Roy Shaham +3
Nuclear spins of noble gases exhibit exceptionally long coherence times and can potentially serve as a long-lived storage medium for quantum information. We analyze and compare the…
Optical quantum memory for noble-gas spins based on spin-exchange collisions
Or Katz, Roy Shaham, Eran Reches +2
Optical quantum memories, which store and preserve the quantum state of photons, rely on a coherent mapping of the photonic state onto matter states that are optically accessible.…
