    ABSTRACT: We propose a novel scheme to generate the spin-orbit coupling for a condensate placed inside an optical cavity by using a standing wave and a traveling wave. It is shown that the interplay of the laser lights and the cavity gives rise to rich quantum phases. Our scheme also generates a large synthetic magnetic field for the dressed spin state, which may facilitate the study of the quantum Hall effect in ultracold atomic gases.

    ABSTRACT: We propose to realize controllable squeezing states of ferromagnetic magnons with a spinor Bose-Einstein condensate confined in an optical lattice. We use an external laser field to induce optical dipole-dipole interaction, which leads to magnon excitations of the system. By focusing on the role of the long-range magnetic and the optical dipole-dipole interactions, we show that the existence and properties of the produced squeezed magnons can be well controlled by tuning the transverse trapping widths of the condensates. We also show that the magnon excitations in this system have a close analogy with the dynamical Casimir effect at finite temperature predicted by Plunien et al. [Phys. Rev. Lett. 84, 1882 (2000)] and Jing et al. [Phys. Lett. A 268, 174 (2000)].

    ABSTRACT: The possibility to coherently control a quantum rotor is investigated theoretically. The rotor is realized by an antiferromagnetic spin-1 Bose-Einstein condensate, trapped in the optical field of a Fabry-Perot resonator. By tuning the pumping field of the resonator, coherent control over the rotor is achieved. The technique is illustrated by the numerical simulation of a protocol that transforms the rotor's ground state into a squeezed state. The detection of the squeezed state via measurement of intensity-correlations of the cavity field is proposed.

    ABSTRACT: We study cavity optomechanics of a mixture of ultracold atoms with tunable nonlinear collisions. We show that atomic collisions provide linear couplings between fictitious condensate oscillators, leading to possibilities of achieving a globally coupled quantum optomechanical network with an integrated atom chip. Potential applications range from simulating collective nonequilibrium dynamics in fields well past physics to probing unique properties of quantum mixtures.

    ABSTRACT: We propose an experimental scheme to create spin-orbit coupling in spin-3 Cr atoms using Raman processes. By employing the linear Zeeman effect and optical Stark shift, two spin states within the ground electronic manifold are selected, which results in a pseudospin-1/2 model. We further study the ground state structures of a spin-orbit-coupled Cr condensate. We show that, in addition to the stripe structures induced by the spin-orbit coupling, the magnetic dipole-dipole interaction gives rise to the vortex phase, in which a spontaneous spin vortex is formed.

    ABSTRACT: In this paper we describe a scheme for state transfer between a trapped atomic Bose condensate and an optomechanical end-mirror mediated by a cavity field. Coupling between the mirror and the cold gas arises from the fact that the cavity field can produce density oscillations in the gas which in turn acts as an internal Bragg mirror for the field. After adiabatic elimination of the cavity field we find that the hybrid system of the gas and mirror is described by a beam splitter Hamiltonian that allows for state transfer, but only if the quantum nature of the cavity field is retained.

    ABSTRACT: We investigate the cavity optomechanical properties of an antiferromagnetic Bose-Einstein condensate, where the role of the mechanical element is played by spin-wave excitations. We show how this system can be described by a single rotor that can be prepared deep in the quantum regime under realizable experimental conditions. This system provides a bottom-up realization of dispersive rotational optomechanics, and opens the door to the direct observation of quantum spin fluctuations.

    ABSTRACT: We investigate the matter-wave analog of rotational optomechanics. That is, in stead of considering the optomechanical coupling of a rotating mechanical element, we study the optomechanical effects associated with spin-wave excitations of a macroscopic mode in an antiferromagnetic Bose-Einstein condensate (BEC) inside a unidirectional ring cavity, relying on the well established fact that the antiferromagnetic BEC can be effectively described as a single quantum rotor characterized by angular momentum and angular displacement. We show that under suitable conditions the optomechanical coupling can be quadratic in angular displacement, and demonstrate how one can measure its eigen-energy nondestructively by observation of the cavity output signal. This model opens the door to the observation of spin-wave quantum jumps, as well as to controllable entanglement between a quantum spin gas and a mechanical element.

    ABSTRACT: We consider the two-color photooassociation of a quantum degenerate atomic gas into ground-state diatomic molecules via a molecular dark state. This process can be described in terms of a lambda level scheme that is formally analogous to the situation in electromagnetically-induced transparency (EIT) in atomic systems, and therefore can result in slow light propagation. We show that the group velocity of the light field depends explicitly on whether the atoms are bosons or fermions, as well as on the existence or absence of a pairing gap in the case of fermions, so that the measurement of the group velocity realizes a non-destructive diagnosis of the atomic state and the pairing gap.

    ABSTRACT: We study theoretically several aspects of the dynamics of coherent atom-molecule conversion in spin-1 Bose-Einstein condensates. Specifically, we discuss how for a suitable dark-state condition the interplay of spin-exchange collisions and photoassociation leads to the stable creation of an atom- molecule pairs from three initial spin-zero atoms. This process involves two two-body interactions and can be intuitively viewed as an effective three-body recombination. We investigate the relative roles of photoassociation and of the initial magnetization in the \resonant" case where the dark state condition is perfectly satisfied. We also consider the "non-resonant" regime, where that condition is satisfied either approximately {the so-called adiabatic case {or not at all. In the adiabatic case, we derive an effective non-rigid pendulum model that allows one to conveniently discuss the onset of an antiferromagnetic instability of an \atom-molecule pendulum," as well as large-amplitude pair oscillations and atom-molecule entanglement.

    ABSTRACT: Based upon standard angular momentum theory, we develop a framework to investigate polarization squeezing and multipartite entanglement of a quantum light field. Both mean polarization and variances of the Stokes parameters are obtained analytically, with which we study recent observation of triphoton states [L. K. Shalm {\it et al}, Nature \textbf{457}, 67 (2009)]. Our results show that the appearance of maximally entangled NOON states accompanies with a flip of mean polarization and can be well understood in terms of quantum Fisher information.

    ABSTRACT: We propose to use a quantized version of coherent two-color photoassociation to realize a hybrid device for quantum control of light. The dynamical features of this system are exhibited, including the slowing down or storage of light and the molecular matter-wave solitons. This may indicate a hybrid atom-molecule quantum device for storage and retrieve of optical information. Comment: with several detailed derivations in comparison with the published version Phys. Rev.

    ABSTRACT: We show theoretically that it is possible to optically control collective spin-exchange processes in spinor Bose condensates through virtual photoassociation. The interplay between optically induced spin exchange and spin-dependent collisions provides a flexible tool for the control of atomic spin dynamics, including enhanced or inhibited quantum spin oscillations, the optically-induced ferromagnetic-to-antiferromagnetic transition, and coherent matter-wave spin conversion.

    ABSTRACT: We study the adiabatic dark-state evolutions in coherent creations of heteronuclear diatomic or triatomic molecules from an ultracold two-species atomic condensate. We find that, for different nonlinear systems, the relations between the adiabatic fidelities and the adiabatic parameters are in a universal power law but with quite different parameters.

    ABSTRACT: We study the role in an external photoassociation light field in the spin mixing dynamics of a spin-one Bose condensate with long-range magnetic dipole-dipole interaction. The mean-field energy functional of the system is found to be formally identical to that of two coupled nonrigid pendulums, manifesting either constructive or destructive interferences. The interplay between photoassociation and the magnetic dipole-dipole interaction provides a novel route to the magneto-optical quantum control of atomic spin mixing in dipolar spinor condensates.

    ABSTRACT: We propose to probe the quantum ground state of a spin-1 Bose-Einstein condensate with the transmission spectra of an optical cavity. By choosing a circularly polarized cavity mode with an appropriate frequency, we can realize coupling between the cavity mode and the magnetization of the condensate. The cavity transmission spectra then contain information of the magnetization statistics of the condensate and thus can be used to distinguish the ferromagnetic and antiferromagnetic quantum ground states. This technique may also be useful for continuous observation of the spin dynamics of a spinor Bose-Einstein condensate.

    ABSTRACT: We investigate the coherent two-color photoassociation (PA) process in a spinor-1 atomic Bose-Einstein condensate by comparing the single-spin and mixed-spin cases. We find that, by tuning the PA light applied on different spin components, one can observe quite different features for the atomic spin-mixing dynamics (with weak PA field) or coherent atom-molecule conversion (with strong PA field), indicating a research field of so-called superchemistry or coherent PA in a spinor gas.

    ABSTRACT: We demonstrate theoretically that the abstraction reaction $A+B_2 \to AB+B$ can be driven coherently and efficiently with quantum-degenerate bosonic or fermionic matter waves. We show that the initial stages of the reaction are dominated by quantum fluctuations, resulting in the appearance of macroscopic non-classical correlations in the final atomic and molecular fields. The dynamics associated with the creation of bosonic and of fermionic dimer-atom pairs are also compared. This study opens up a promising new regime of quantum degenerate matter-wave chemistry.

    ABSTRACT: In this paper, we propose a feasible scheme to create macroscopic atom-molecule entanglement from a two-species atomic Bose-Einstein condensate, focusing on the role of the initial populations imbalance Δ of the two species. We find that, by tuning the value of Δ and/or the initial quantum statistics of the atoms, the atom-heteronuclear molecule entanglement can be indeed realized.

    ABSTRACT: We study the quantum conversion from light to ultracold triatomic molecules by using a quantized photoassociation light. Our results show that molecular matter-wave squeezing can be obtained for both homo- and hetero-nuclear trimers and are also compared with the previously studied case of creating dimers. This provides a possible method for quantum control of ultracold complex objects.
