Universal joint-measurement uncertainty relation for error bars
Paul Busch, David B. Pearson
We formulate and prove a new, universally valid uncertainty relation for the necessary errors bar widths in any approximate joint measurement of position and momentum.
Reflection equation and twisted Yangians
Andrey Mudrov
With any involutive anti-algebra and coalgebra automorphism of a quasitriangular bialgebra we associate a reflection equation algebra. A Hopf algebraic treatment of the reflection…
Bending and stretching unit vector fields in Euclidean and hyperbolic 3-space
C. M. Wood
New examples of harmonic unit vector fields on hyperbolic 3-space are constructed by exploiting the reduction of symmetry arising from the foliation by horospheres. This is compare…
Evolution in Materio: Exploiting the Physics of Materials for Computation
Simon L. Harding, Julian F. Miller, Edward A. Rietman
We describe several techniques for using bulk matter for special purpose computation. In each case it is necessary to use an evolutionary algorithm to program the substrate on whic…
The disentangling power of unitaries
Lieven Clarisse, Sibasish Ghosh, Simone Severini +1
We define the disentangling power of a unitary operator in a similar way as the entangling power defined by Zanardi, Zalka and Faoro [PRA, 62, 030301]. A general formula is derived…
A set theoretic framework for enumerating matches in surveys and its application to reducing inaccuracies in vehicle roadside surveys
Richard G. Clegg
This paper describes a framework for analysing matches in multiple data sets. The framework described is quite general and can be applied to a variety of problems where matches are…
