String Axiverse
String theory suggests the simultaneous presence of many ultralight axions, possibly populating each decade of mass down to the Hubble scale 10−33eV. Conversely the presence of such a plenitude of axions (an “axiverse”) would be evidence for string theory, since it arises due to the topological complexity of the extra-dimensional manifold and is ad hoc in a theory with just the four familiar di...
متن کاملPropagating waves in an extremal black string
We investigate the black string in the context of the string theories. It is shown that the graviton is the only propagating mode in the (2+1)– dimensional extremal black string background. Both the dilation and axion turn out to be non-propagating modes.
متن کاملCutoff frequencies of electromagnetic waves Propagating in a hexagonal waveguide
Abstract-In this work, cut-off frequencies of propagation of electromagnetic waves in a hexagonal waveguide are calculated using twodimensional (2-D) finite element method. The numerical approach is a standard one and involves six finite elements. A new type of hexagonal waveguide structure for the simple homogeneous dielectric case has been considered. The starting point is Maxwell’s equations...
متن کاملPropagating Waves in Visual Cortex
Spatiotemporal patterns of cortical activation occur superimposed upon sensory, motor, and cognitive maps. The papers by Benucci et al. and Xu et al. in this issue of Neuron demonstrate that visual responses propagate in space and may serve to link different visual areas. This is an important step toward understanding how cortical maps relate to activation patterns, a prerequisite to understand...
متن کاملSingular polarimetry: evolution of polarization singularities in electromagnetic waves propagating in a weakly anisotropic medium.
We describe the evolution of a paraxial electromagnetic wave characterizing by a non-uniform polarization distribution with singularities and propagating in a weakly anisotropic medium. Our approach is based on the Stokes vector evolution equation applied to a non-uniform initial polarization field. In the case of a homogeneous medium, this equation is integrated analytically. This yields a 3-d...
