Energy bounds for the spinless Salpeter equation: harmonic oscillator [PDF]

open access: yes, 2000
We study the eigenvalues E_{n\ell} of the Salpeter Hamiltonian H = \beta\sqrt(m^2 + p^2) + vr^2, v>0, \beta > 0, in three dimensions. By using geometrical arguments we show that, for suitable values of P, here provided, the simple semi-classical formula ...

A note on Duffin-Kemmer-Petiau equation in (1+1) space-time dimensions [PDF]

open access: yes, 2017
In the last years several papers addressed the supposed spin-1 sector of the massive Duffin-Kemmer-Petiau (DKP) equation restricted to (1+1) space-time dimensions.

Electrodynamics in Euclidean Space Time Geometries

open access: yesOpen Physics, 2019
In this article it is proven that Maxwell’s field equations are invariant for a real orthogonal Cartesian space time coordinate transformation if polarization and magnetization are assumed to be possible in empty space. Furthermore, it is shown that this

Dirac oscillator in DSR: A comparative study of Magueijo–Smolin and Amelino-Camelia models

open access: yesPhysics Letters B
This investigation examines the one-dimensional Dirac oscillator in the framework of Doubly Special Relativity (DSR), with a comparative analysis of the Magueijo–Smolin (MS) and Amelino-Camelia (AC) formulations up to order O(E2/k2).

Quench dynamics and parity blocking in Majorana wires

open access: yesNew Journal of Physics, 2015
We theoretically explore quench dynamics in a finite-sized topological fermionic p -wave superconducting wire with the goal of demonstrating that topological order can have marked effects on such non-equilibrium dynamics.

What is the relativistic spin operator?

open access: yesNew Journal of Physics, 2014
Although the spin is regarded as a fundamental property of the electron, there is no universally accepted spin operator within the framework of relativistic quantum mechanics.

Exact Green’S Function for 2D Dirac Oscillator in Constant Magnetic Field

open access: yes, 2007
The propagator of two-dimensional Dirac oscillator in the presence of a constant magnetic field is presented by means of path integrals, where the spin degree-of-freedom is described by odd Grassmannian variables and the gauge invariant part of the ...

Electron-spin dynamics induced by photon spins

open access: yesNew Journal of Physics, 2014
Strong rotating magnetic fields may cause a precession of the electronʼs spin around the rotation axis of the magnetic field. The superposition of two counterpropagating laser beams with circular polarization and opposite helicity features such a ...

Exact solutions of Dirac equation on (1+1)-dimensional spacetime coupled to a static scalar field

open access: yes, 2005
We use a generalized scheme of supersymmetric quantum mechanics to obtain the energy spectrum and wave function for Dirac equation in (1+1)-dimensional spacetime coupled to a static scalar field.Comment: 7 pages ...

Continuous spin superparticle model

open access: yesPhysics Letters B
We construct a new model of a particle propagating in 4D, N=1 superspace that describes the dynamics of a continuous spin irreducible representation of the Poincaré supergroup.
