Nonconservation of Energy and Loss of Determinism I. Infinitely Many Balls
David Atkinson, Porter Johnson
An infinite number of elastically colliding balls is considered in a classical, and then in a relativistic setting. Energy and momentum are not necessarily conserved globally, even…
Nonconservation of Energy and Loss of Determinism II: Colliding with an Open Set
David Atkinson, Porter Johnson
An actual infinity of colliding balls can be in a configuration in which the laws of mechanics lead to logical inconsistency. It is argued that one should therefore limit the domai…
Gambler's Ruin? Some Aspects of Coin Tossing
Porter W. Johnson, David Atkinson
What is the average number of tosses needed before a particular sequence of heads and tails turns up? We solve the problem didactically, starting with doubles, finding that a tail,…
Joint Probabilities Reproducing Three EPR Experiments On Two Qubits
S. M. Roy, D. Atkinson, G. Auberson +2
An eight parameter family of the most general nonnegative quadruple probabilities is constructed for EPR-Bohm-Aharonov experiments when only 3 pairs of analyser settings are used.…
Running Coupling in Non-Perturbative QCD - I. Bare Vertices and y-max Approximation
D. Atkinson, J. C. R. Bloch
A recent claim that in quantum chromodynamics the gluon propagator vanishes in the infrared limit, while the ghost propagator is more singular than a simple pole, is investigated a…
Chiral Symmetry Breaking with the Curtis-Pennington Vertex
D. Atkinson, V. P. Gusynin, P. Maris
We study chiral symmetry breaking in quenched QED, using a vertex Ansatz recently proposed by Curtis and Pennington. Bifurcation analysis is employed to establish the existence…
