Truncating the potential and recasting Schrodinger's equation in first-order form comprise an approach to finding the wavefunction called "variable" .
Truncating the potential and recasting Schrodinger's equation in first-order form comprise an approach to finding the wavefunction called "variable" . Particle number in QED and QCD is conserved because the Lagrangian is invariant under a change in this quantity. The total scattering cross-section from a central potential can be expressed entirely in terms of the wavenumber and the change in this quantity using the (*) partial wave approximation. The difference in this quantity equals electron charge times the solenoid flux divided by h-bar for two branches of a wire passing around a solenoid. The magnetic vector potential gives rise to a change in this quantity even when the magnetic field itself is zero in the Aharonov-Bohm effect. For 10 points, name this quantity which along with a real amplitude can specify any plane wave.
