“…As it was quite recently shown, the steering effect, besides its commonly discussed form which is related to the EPR nonlocality [2], has its temporal [3][4][5] and spatiotemporal forms [6].

We consider the possibility of generation steerable states in Bose-Hubbard system composed of three interacting wells in the form of a triangle. We show that although our system still fulfills the monogamy relations, the presence of additional coupling which transforms a chain of wells onto triangle gives a variety of new possibilities for the generation of steerable quantum states. Deriving analytical formulas for the parameters describing steering and bipartite entanglement, we show that interplay between two couplings influences quantum correlations of various types. We compare the time evolution of steering parameters to those describing bipartite entanglement and find the relations between the appearance of maximal entanglement and disappearance of steering effect.

“…However, no significance signal was obtained for Z 0 b (10650). The structures of the charged charmonium-like and bottomoniumu-like states discussed above have been studied theoretically in the hadronic-molecular approaches [15,59,, in the hadrocharmonium approach [229], in the QCD sum rule approaches [104,[230][231][232][233][234][235][236][237][238][239][240][241], in the tetraquark approaches [242][243][244][245][246][247][248][249][250][251], in the heavy quark spin symmetry approaches [99,204,252,253] and in the lattice QCD approaches [254][255][256][257][258][259][260].

We discuss selected and important features of hadronic molecules as one of promising forms of exotic hadrons near thresholds. Using examples of DD * systems such as X(3872) and Z c , emphasis is put on the roles of the one pion exchange interaction between them and their coupling to intrinsic quark states. Thus hadronic molecules emerge as admixtures of the dominant long-range hadron structure and short-range quark structure. For the pion exchange interaction, properties of the tensor force are analyzed in detail. More coupled channels supply more attractions, and heavier constituents suppress kinetic energies, providing more chances to form hadronic molecules of heavy hadrons. Throughout this article, we show details of basic ideas and methods. ‡ More complete references are given in section 4.1 for X(3872) and in section 5.1 for Z c and Z b . arXiv:1908.08790v1 [hep-ph] 23 Aug 2019 § Here D ( * ) stands for either D or D * meson. In this article we do not consider systems containing strange quarks, and therefore the notation q is used for light u, d quarks.

“…Leaving behind the standard system of one optical mode coupled to one mechanical mode, we arrive at optomechanical arrays (see e.g. [2][3][4][5][6][7][8][9][10][11][12][13] ). These are comprised of a set of coupled vibrational and optical modes.…”

Quench dynamics in one-dimensional optomechanical arrays

Non-equilibrium dynamics induced by rapid changes of external parameters is relevant for a wide range of scenarios across many domains of physics. For waves in spatially periodic systems, quenches will alter the bandstructure and generate new excitations. In the case of topological bandstructures, defect modes at boundaries can be generated or destroyed when quenching through a topological phase transition. Here, we demonstrate that optomechanical arrays are a promising platform for studying such dynamics, as their bandstructure can be tuned temporally by a control laser. We study the creation of nonequilibrium optical and mechanical excitations in 1D arrays, including a bosonic version of the Su-Schrieffer-Heeger model. These ideas can be transferred to other systems such as driven nonlinear cavity arrays. arXiv:1907.04293v1 [quant-ph]
