Constructing the Hamiltonian for a free 1D KFGM particle in an interval
Techapon Kampu, Salvatore De Vincenzo
We analyze the problem of a free 1D Klein-Fock-Gordon-Majorana (KFGM) particle in an interval. By free, we mean that there is no potential within the interval and that its walls ar…

Nontrivial local observables and impermeable and permeable boundary conditions for 1D KFGM particles
Techapon Kampu, Salvatore De Vincenzo
Real solutions of the 1D Klein-Fock-Gordon (KFG) equation automatically cancel out the usual two-vector current density; consequently, the respective continuity equation is trivial…

On the locus formed by the maximum heights of an ultra-relativistic projectile
Salvatore De Vincenzo
We consider the problem of relativistic projectiles in a uniform gravitational force field in an inertial frame. For the first time, we have found the curve that joins the points o…
