• Title: Bundle Theoretic Descriptions of Massless Single-Particle State Spaces; How do we perceive a moving quantum particle
• Authors: Heon Lee
• Abstract summary: We show that the gauge freedoms of Electromagnetism and General Relativity naturally arise as manifestations of an inertial observer's perception of the internal quantum states of a photon and a graviton. We show that gauge freedom is exhibited by all massless particles, except those with spin-0 and 1/2.

• Abstract: Recently, a bundle theoretic description of massive single-particle state spaces, which is better suited for Relativistic Quantum Information Theory than the ordinary Hilbert space description, has been suggested. However, the mathematical framework presented in that work does not apply to massless particles. It is because, unlike massive particles, massless particles cannot assume the zero momentum state and hence the mass shell associated with massless particles has non-trivial cohomology. To overcome this difficulty, this paper suggests a new framework that can be applied to massless particles. Applications to the cases of massless particles with spin-1 and 2, namely photon and graviton, will reveal that the field equations, the gauge conditions, and the gauge freedoms of Electromagnetism and General Relativity naturally arise as manifestations of an inertial observer's perception of the internal quantum states of a photon and a graviton, respectively. Finally, we show that gauge freedom is exhibited by all massless particles, except those with spin-0 and 1/2.

  We show that the stability of particle trajectories on the brane gives us the Bohr--Sommerfeld quantization condition. The particle's motion along the extra dimension allows us to formulate a geometrical version of the uncertainty principle. We show that the particle's motion along the extra dimension yields a quantized energy spectrum for bound states.

• Effects of photon field on entanglement generation in charged particles [0.0]
  We analyze the entanglement generation between two charged particles coupled to a photon field. It is observed that the entanglement is suppressed by the decoherence due to the vacuum fluctuations of the photon field. The similar structures between the gravity theory and electromagnetic theory suggests that a similar feature may be observed in the entanglement generation by quantum gravitational radiation.

  The momentum eigen-value equation with quaternionic mass yields the Klein-Gordon equation with a mass consisting of longitudinal and traverse masses. A quantum force acting on the particle is found to be proportional to its velocity. When the particle field is coupled to an electromagnetic field, an additional term in the particle's energy appears reflecting the interaction of the particle's angular momentum with the magnetic field.
