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…

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…

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…

NASDUCK: New Constraints on Axion-like Dark Matter from Floquet Quantum Detector

Itay M. Bloch, Gil Ronen, Roy Shaham +3

We report on the first results of the Noble and Alkali Spin Detectors for Ultralight Coherent darK matter (NASDUCK) collaboration. We search for the interactions of Axion-Like Part…

Strong coupling of alkali spins to noble-gas spins with hour-long coherence time

Roy Shaham, Or Katz, Ofer Firstenberg

Nuclear spins of noble gases can maintain coherence for hours at ambient conditions owing to their extraordinary isolation by the enclosing, complete electronic shells. This isolat…

Coupling light to a nuclear spin gas with a two-photon linewidth of five millihertz

Or Katz, Roy Shaham, Ofer Firstenberg

Nuclear spins of noble gases feature extremely long coherence times but are inaccessible to optical photons. Here we realize a coherent interface between light and noble-gas spins…

Quantum Dynamics of Collective Spin States in a Thermal Gas

Roy Shaham, Or Katz, Ofer Firstenberg

Ensembles of alkali or noble-gas atoms at room temperature and above are widely applied in quantum optics and metrology owing to their long-lived spins. Their collective spin state…

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.…

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…

Long-lived entanglement generation of nuclear spins using coherent light

Or Katz, Roy Shaham, Eugene S. Polzik +1

Nuclear spins of noble-gas atoms are exceptionally isolated from the environment and can maintain their quantum properties for hours at room temperature. Here we develop a mechanis…

Quantum interface for noble-gas spins based on spin-exchange collisions

Or Katz, Roy Shaham, Ofer Firstenberg

An ensemble of noble-gas nuclear spins is a unique quantum system that could maintain coherence for many hours at room temperature and above, owing to exceptional isolation from th…
