Tunneling between bilayer quantum Hall structures in a strong magnetic field

We calculate the tunneling current in a quantum Hall bilayer system in the strong magnetic field limit. We model the bilayer electron system as two Wigner crystals coupled through interlayer Coulomb interactions, treated in the continuum limit. We generalized the Johansson and Kinaret (JK) model and were able to study the effect of the low energy out-of-phase magnetophonon modes produced as a result of tunneling events. We find the same scaling behavior of the tunneling current peak with the magnetic field as found by JK but were able to find the tunneling current scaling behavior with interlayer distance as well.Comment: 4 pages, 1 figure, SemiMag16 conference paper to be published in International Journal of Modern Physics

The Impact of Integration Strategies on Food Business Firm Value

The objective of this study is to analyze whether a discount or premium exists for coordination strategies in food processing, wholesale grocery, retail supermarkets, and restaurants. Significant premiums are found for food processor and restaurant vertical integration or diversification strategies. Significant discounts are found for food wholesaler and retail supermarket integration or diversification strategies. Food processors are found to be integrating toward retail supermarkets during this time period.agribusiness, food, institutional economics, integration, Agribusiness, Agricultural and Food Policy, Industrial Organization, Institutional and Behavioral Economics, Q13, L66, L14,

Vortex Lattice Structural Transitions: a Ginzburg-Landau Model Approach

We analyze the rhombic to square vortex lattice phase transition in anisotropic superconductors using a variant of Ginzburg-Landau (GL) theory. The mean-field phase diagram is determined to second order in the anisotropy parameter, and shows a reorientation transition of the square vortex lattice with respect to the crystal lattice. We then derive the long-wavelength elastic moduli of the lattices, and use them to show that thermal fluctuations produce a reentrant rhombic to square lattice transition line, similar to recent studies which used a nonlocal London model.Comment: 4 pages, 3 figures, final version with various referee suggested modifications, scheduled to appear in PR
