A periodic composite of four isotropic phases with an almost antisymmetric effective Hall matrix is constructed. This is done through the use of a microstructure, with high contrast conductivity, which acts to twist the direction of the induced Hall field. For an applied current along the y3 axis and a magnetic field h in the y1-y2 plane the Hall field will be essentially parallel, rather than ...

Considering a generic double-ring collider, we discuss the matching from an antisymmetric optics in the arcs to a symmetric optics in the interaction region (IR) by means of an antisymmetric matching section. As an example, we present an application to the LHC, for which a symmetric IR with extremely flat beams is under study.

In this brief note we construct the propagator for the antisymmetric tensor in AdSd+1. We check our result using the Poincaré duality between the antisymmetric tensor and the gauge boson in AdS5. This propagator was needed for a computation which turned out to be too hard. It can be used for computing various other things in AdS. Typeset using REVTEX

Using previously developed potential energy surfaces and their couplings, non-Born-Oppenheimer trajectory methods are used to study the state-selected photodissociation of ammonia, prepared with up to six quanta of vibrational excitation in the symmetric (nu(1)) or antisymmetric (nu(3)) stretching modes of NH(3)(A). The predicted dynamics is mainly electronically nonadiabatic (that is, it produ...

A gauge invariant formulation for the massive axion is considered. The axion acquires mass through a topological term which couples a (pseudo)scalar and a third rank antisymmetric tensor. The dual, local and canonical equivalences with the non-gauge invariant proposal are established. The supersymmetric version is constructed. In four dimensions a massless (pseudo)scalar field: the axion, is du...
