Hertzian Dipole Radiation via the Weizsacker-Williams Model
Kirk T. McDonald, Max S. Zolotorev
We use the Weizsacker-Williams method to deduce the radiated power, and its angular distribution, emitted by an electron of charge that undergoes simple harmonic motion.
Electron Bubbles in Liquid Helium
Kirk T. McDonald
When an electron (or positronium atom) is injected into liquid helium with nearly zero energy, a bubble quickly forms around it. This phenomenon (which also occurs in liquid hydrog…
Uncertainties in the Measurement of the Momentum and Position of an Electron
Kirk T. McDonald
It has been suggested that the uncertainty in the measurement of a particle's momentum could be made arbitrarily small by observing the particle at two ends of an arbitrarily long…
Bunching of Photons When Two Beams Pass Through a a Beam Splitter
K. T. McDonald, L. J. Wang
Dirac has written "Each photon then interferes only with itself. Interference between two different photons never occurs." Indeed, a practical definition is that "classical" optics…
A Capacitor Paradox
Kirk T. McDonald
Consider two capacitors in parallel, but initially isolated by a switch such that one is charged and the other not. After the switch is closed, the charges redistribute themselves…
A Conducting Checkerboard
Kirk T McDonald
The problem of a conducting checkerboard has recently been solved via an elliptic function whose argument is another elliptic function. The behavior of the fields and currents near…
