	abstract = {<p>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. Here we outline a new physical mechanism to map the state of photons onto the long-lived but optically inaccessible collective state of noble-gas spins. The mapping employs the coherent spin-exchange interaction arising from random collisions with alkali vapor. We analyze optimal strategies for high-efficiency storage and retrieval of non-classical light at various parameter regimes. Based on these strategies, we identify feasible experimental conditions for realizing efficient quantum memories with noble-gas spins having hours-long coherence times at room temperature and above</p>},

	abstract = {  We propose a scheme for realizing fractional quantum Hall states of light. In
our scheme, photons of two polarizations are coupled to different atomic
Rydberg states to form two flavors of Rydberg polaritons that behave as an
effective spin. An array of optical cavity modes overlapping with the atomic
cloud enables the realization of an effective spin-1/2 lattice. We show that
the dipolar interaction between such polaritons, inherited from the Rydberg
states, can be exploited to create a flat, topological band for a single
spin-flip excitation. At half filling, this gives rise to a photonic (or
polaritonic) fractional Chern insulator -- a lattice-based, fractional quantum
Hall state of light.
