Fractional Angular Momenta, Gouy and Berry phases in Relativistic Bateman-Hillion-Gaussian Beams of Electrons
Robert J. Ducharme, Irismar Gonçalves da Paz, Armen G. Hayrapetyan
A new Bateman-Hillion solution to the Dirac equation for a relativistic Gaussian electron beam taking explicit account of the -position of the beam waist is presented. This solu…
Nonuniform currents and spins of relativistic electron vortices in a magnetic field
Koen van Kruining, Armen G. Hayrapetyan, Jörg B. Götte
We present a relativistic description of electron vortex beams in a homogeneous magnetic field. Including spin from the beginning reveals that spin-polarized electron vortex beams…
Electromagnetic wave propagation in spatially homogeneous yet smoothly time-varying dielectric media
Armen G. Hayrapetyan, Jörg B. Götte, Karen K. Grigoryan +2
We explore the propagation and transformation of electromagnetic waves through spatially homogeneous yet smoothly time-dependent media within the framework of classical electrodyna…
Quantized form factor shift in the presence of free electron laser radiation
F. Fratini, L. Safari, A. G. Hayrapetyan +3
In electron scattering, the target form factors contribute significantly to the diffraction pattern and carry information on the target electromagnetic charge distribution. Here we…
Instantaneous modulations in time-varying complex optical potentials
Armen G. Hayrapetyan, S. P. Klevansky, Joerg B. Goette
We study the impact of a spatially homogeneous yet non-stationary dielectric permittivity on the dynamical and spectral properties of light. Our choice of potential is motivated by…
Radiative Capture of Twisted Electrons by Bare Ions
Oliver Matula, Armen G. Hayrapetyan, Valeriy G. Serbo +2
Recent advances in the production of twisted electron beams with a subnanometer spot size offer unique opportunities to explore the role of orbital angular momentum (OAM) in basic…
Atomic ionization by twisted photons: Angular distribution of emitted electrons
Oliver Matula, Armen G Hayrapetyan, Valeriy G Serbo +2
We investigate the angular distribution of electrons that are emitted in the ionization of hydrogen-like ions by twisted photons. Analysis is performed based on the first-order per…
Bessel beams of two-level atoms driven by a linearly polarized laser field
Armen G. Hayrapetyan, Oliver Matula, Andrey Surzhykov +1
We study Bessel beams of two-level atoms that are driven by a linearly polarized laser field. Starting from the Schroedinger equation, we determine the states of two-level atoms in…
Underlining some limitations of the statistical formalism in quantum mechanics: Reply to the Comment of Bodor and Diósi
F. Fratini, A. G. Hayrapetyan
In a paper of us, it is showed that Density Matrices do not provide a complete description of ensembles of states in quantum mechanics, since they lack measurable information conce…
Underlining some limitations of the statistical formalism in quantum mechanics
Filippo Fratini, Armen G. Hayrapetyan
We show that two chosen ensembles of spin states, which are differently prepared but are described by the same density matrix in quantum mechanics, do not fully share the same meas…
