Polaritonic characteristics of insulator and superfluid phases in a coupled-cavity array

Recent studies of quantum phase transitions in coupled atom-cavity arrays have focused on the similarities between such systems and the Bose-Hubbard model. However, the bipartite nature of the atom-cavity systems that make up the array introduces some differences. In order to examine the unique features of the coupled-cavity system, the behavior of a simple two-site model is studied over a wide range of parameters. Four regions are identified, in which the ground state of the system may be classified as either a polaritonic insulator, a photonic superfluid, an atomic insulator, or a polaritonic superfluid.Comment: 7 pages, 9 figures, 1 table, REVTeX 4; published versio

Mixing-induced fluid destratification and ullage condensation

In many applications, on-orbit storage and transfer of cryogens will require forced mixing to control tank pressure without direct venting to space. During a no-vent transfer or during operation of a thermodynamic vent system in a cryogen storage tank, pressure control is achieved by circulating cool liquid to the liquid-vapor interface to condense some of the ullage vapor. To measure the pressure and temperature response rates in mixing-induced condensation, an experiment has been developed using Freon 11 to simulate the two-phase behavior of a cryogen. A thin layer at the liquid surface is heated to raise the tank pressure, and then a jet mixer is turned on to circulate the liquid, cool the surface, and reduce the pressure. Many nozzle configurations and flow rates are used. Tank pressure and the temperature profiles in the ullage and the liquid are measured. Initial data from this ground test are shown correlated with normal-gravity and drop-tower dye-mixing data. Pressure collapse times are comparable to the dye-mixing times, whereas the times needed for complete thermal mixing are much longer than the dye-mixing times

Dynamics in a coupled-cavity array

The dynamics of a system composed of two coupled optical cavities, each containing a single two-level atom, is studied over a wide range of detuning and coupling values. A description of the field in terms of delocalized modes reveals that the detuning between the atoms and these modes is controlled by the coupling between the cavities; this detuning in turn governs the nature of the dynamics. If the atoms are highly detuned from both delocalized field modes, the dynamics becomes dispersive and an excitation may be transferred from the first atom to the second without populating the field. In the case of resonance between the atoms and one of the delocalized modes, state transfer between the atoms requires intermediate excitation of the field. Thus the interaction between the two atoms can be controlled by adjusting the coupling between the cavities.Comment: 11 pages, 3 figure

Cross-Kerr-based information transfer processes

The realization of nonclassical states is an important task for many applications of quantum information processing. Usually, properly tailored interactions, different from goal to goal, are considered in order to accomplish specific tasks within the general framework of quantum state engineering. In this paper we remark on the flexibility of a cross-Kerr nonlinear coupling in hybrid systems as an important ingredient in the engineering of nonclassical states. The general scenario we consider is the implementation of high cross-Kerr nonlinearity in cavity-quantum electrodynamics. In this context, we discuss the possibility of performing entanglement transfer and swapping between a qubit and a continuous-variable state. The recently introduced concept of entanglement reciprocation is also considered and shown to be possible with our scheme. We reinterpret some of our results in terms of applications of a generalized Ising interaction to systems of different nature.Comment: 8 pages, 4 figures, RevTeX

An examination of the use of the verb ‘Haya’ (ה'ה) ‘be’ in biblical Hebrew

The accompanying thesis details the way in which the Hebrew verb ‘Haya’ (h), ‘b’ functions. The study begins by summarising briefly the threefold aspect of the verb 'be', (i) as Copula, (ii) as expressing 'Existence', and (iii) to denote Transition or 'Becoming'. It is shown how each aspect has its basic syntax as regards subject definition and the nature of the predicate, such that a defined nominal subject, an adjectival or nominal predicate is normally associated with a Copula usage, whilst undefined nominal subjects and adverbial predicates usually denote Existence. The transitional aspect is expressed by the verb and the preposition '1', 'to'. From this point the use of ‘Haya’ (h) in its two themes, and Niphal, are thoroughly investigated. It becomes increasingly evident that its more particular function is to locate a situation or event more specifically in time rather than point to the nature of that action as complete or incomplete. The Perfect, Perfect with weak waw, Imperfect Consecutive and Preterite Imperfect 'tenses' indicate past time, and Imperfect, Imperfect with weak waw, and Perfect Consecutive 'tenses' speak of the future. This temporal indication is also the specific function of the verb 'haya (h)' when used "non-integrally" at the commencement of clauses. An explanation is offered for the non-appearance of the verb 'haya’ (h) ' in any other theme, and in particular how the 'causative' connotation is conveyed. Before moving to a consideration of the two particles 'yes' 'there is', and ‘ayin', 'there is not' and their role as supplementing the verb ‘Haya’ (h) by denoting "pfesent existence, the increasing use of that verb in compound with participles is traced. The conclusions are listed more formally and in the Appendices every occurrence of the verb is given for ease of reference
