Probability Density in Relativistic Quantum Mechanics
Taeseung Choi, Yeong Deok Han
In the realm of relativistic quantum mechanics, we address a fundamental question: Which one, between the Dirac or the Foldy-Wouthuysen density, accurately provide a probability de…
Lorentz-Covariant Spin Operator for Spin 1/2 Massive Fields As a Physical Observable
Taeseung Choi, Yeong Deok Han
We derive a relativistic-covariant spin operator for massive case directly from space-time symmetry in Minkowski space-time and investigate the physical properties of a derived spi…
Singularity of relativistic vortex beam and proper relativistic observables
Yeong Deok Han, Taeseung Choi, Sam Young Cho
We have studied the phase singularity of the relativistic vortex beams for the two sets of relativistic operators. One includes the new spin and orbital angular momentum (OAM) oper…
Classical understanding of the electron vortex beams in a uniform magnetic field
Yeong Deok Han, Taeseung Choi
Recently interesting observations on electron vortex beams, which have angular momentum about the center of the vortex beams, have been made. We have shown that the basic features…
Relativistic Spin and Dirac Spin in relativistically covariant Stern-Gerlach Experiment
Taeseung Choi, Yeong Deok Han
We have studied a relativistically covariant Stern-Gerlach (SG) experiment for a relativistic spin and a Dirac spin. We have obtained the relativistic spin in an arbitrary frame by…
Quantum Probability assignment limited by relativistic causality
Yeong Deok Han, Taeseung Choi
The quantum nonlocality is limited by relativistic causality, however, the reason is not fully understood yet. The relativistic causality condition on nonlocal correlations has bee…
