چکیده

We show analytically that the Zitterbewegung and Klein Paradox, such well known aspects of the Dirac Equation are not found in the case of Bosons. We use the Kemmer-Duffin-Harish Chandra formalism with β matrices to arrive at our results.

The bosonic birthday paradox

We motivate and prove a version of the birthday paradox for k identical bosons in n possible modes. If the bosons are in the uniform mixed state, also called the maximally mixed quantum state, then we need k p n bosons to expect two in the same state, which is smaller by a factor of p 2 than in the case of distinguishable objects (boltzmannons). While the core result is elementary, we generaliz...

Finite Difference-Time Domain solution of Dirac equation and the Klein Paradox

The time-dependent Dirac equation is solved using the three-dimensional Finite Difference-Time Domain (FDTD) method. The dynamics of the electron wave packet in a scalar potential is studied in the arrangements associated with the Klein paradox: potential step barriers and linear potentials. No Klein paradox is observed.

Optoelectronic Simulation of the Klein Paradox based on Negative Refraction Phenomenon

Having shown elsewhere [1] that the Klein paradox for the Klein-Gordon (KG) equation of spin-zero particle manifests exactly the same kind of wave propagation and negative refraction phenomena, which also exist in the scattering of TM (transverse-magnetic) –polarized electromagnetic (EM) wave incident on a left handed medium (LHM), we show in this paper that it is possible to simulate the Klein...

Bosonic analog of the Klein paradox

The standard Klein paradox describes how an incoming electron scatters off a supercritical electrostatic barrier that is so strong that it can generate electron-positron pairs. This fermionic system has been widely discussed in textbooks to illustrate some of the discrepancies between quantum mechanical and quantum field theoretical descriptions for the pair creation process. We compare the fer...

Gauge bosons in a five-dimensional theory with localized gravity

We consider the possibility of gauge bosons living in the recently proposed fivedimensional theory with localized gravity. We study the mass spectrum of the Kaluza-Klein (KK) excitations of the gauge fields and calculate their couplings to the boundaries of the fifth dimension. We find a different behaviour from the case of the graviton. In particular, we find that the massless mode is not loca...
