Cubic Curves, Finite Geometry and Cryptography
A. A. Bruen, J. W. P. Hirschfeld, D. L. Wehlau
Some geometry on non-singular cubic curves, mainly over finite fields, is surveyed. Such a curve has 9,3,1 or 0 points of inflexion, and cubic curves are classified accordingly. Th…
Sparse Random Approximation and Lossy Compression
M. Andrecut
We discuss a method for sparse signal approximation, which is based on the correlation of the target signal with a pseudo-random signal, and uses a modification of the greedy match…
Collinearities in Kinetic Point Sets
Ben D. Lund, George B. Purdy, Justin W. Smith +1
Let be a set of points in the plane, each point moving along a given trajectory. A {\em -collinearity} is a pair of a line and a time such that conta…
Towards Antihydrogen Trapping and Spectroscopy at ALPHA
Eoin Butler, Gorm. B. Andresen, Mohammad. D. Ashkezari +37
Spectroscopy of antihydrogen has the potential to yield high-precision tests of the CPT theorem and shed light on the matter-antimatter imbalance in the Universe. The ALPHA antihyd…
Centrifugal separation and equilibration dynamics in an electron-antiproton plasma
G. B. Andresen, M. D. Ashkezari, M. Baquero-Ruiz +34
Charges in cold, multiple-species, non-neutral plasmas separate radially by mass, forming centrifugally-separated states. Here, we report the first detailed measurements of such st…
Alpha Antihydrogen Experiment
ALPHA Collaboration, M. C. Fujiwara, G. B. Andresen +37
ALPHA is an experiment at CERN, whose ultimate goal is to perform a precise test of CPT symmetry with trapped antihydrogen atoms. After reviewing the motivations, we discuss our re…
