Visualizing the kinematics of relativistic wave packets

چکیده
This article presents visualizations of some solutions of the timedependent free Dirac equation. They illustrate some of the strange phenomena which are caused by the interference of positiveand negative-energy waves. We discuss, in particular, the conditions for the occurrence of effects like the Zitterbewegung , the opposite direction of momentum and velocity in negative-energy wave packets, and the superluminal propagation of the wave packet’s local maxima.

Physics Involved in Neutrino Oscillation
Neutrino oscillation is discussed with emphases placed more on its conceptual aspects. After reviewing the two conventional formulations, referred to here as the same-energy prescription and the same-momentum prescription, wave packet treatments are developed for each of these two prescriptions. Both wave packets localized in space and those in time are considered, and, by invoking relativistic...

Asymptotically exact and nonlocal fourth order nonlinear evolution equations are derived for two coupled fourth order nonlinear evolution equations have been derived in deep water for two capillary-gravity wave packets propagating in the same direction in the presence of wind flowing over water.We have used a general method, based on Zakharov integral equation.On the basis of these evolution eq...
متن کاملMinimal Position-Velocity Uncertainty Wave Packets in Relativistic and Non-relativistic Quantum Mechanics
We consider wave packets of free particles with a general energymomentum dispersion relation E(p). The spreading of the wave packet is determined by the velocity v = ∂pE. The position-velocity uncertainty relation ∆x∆v ≥ 1 2 |〈∂2 pE〉| is saturated by minimal uncertainty wave packets Φ(p) = A exp(−αE(p) + βp). In addition to the standard minimal Gaussian wave packets corresponding to the non-rel...

We have studied the formation of relativistic solitary waves due to nonlinearinteraction of strong electromagnetic wave with the plasma wave. Here, our plasma isrelativistic both in temperature and in streaming speed. A set of equations consisting ofscalar and vector potentials together with a third order equation for the enthalpy inphoton gas plasma is obtained analytic...
