Propagators of singular anharmonic oscillators with quasi-equidistant spectra
Andrey M. Pupasov-Maksimov, Marcelo Silva Oliveira
Darboux transformations of the singular harmonic oscillator are considered. Analytical expressions for the propagators are obtained, using the image method applied to formal singul…
Controversy of quantum congestion in two-particle quantum walks
A. D. Lobanova, A. D. Lobanov, A. M. Pupasov-Maksimov
The article deals with one- and two-particle quantum walks on a graph with Braess-like topology and analyzes the issue of network congestion in the quantum world. Our approach to t…
The passage of a vortex electron over an inclined grating
A. Pupasov-Maksimov, D. Karlovets
We study Smith-Purcell radiation from a conducting grating generated by an inclined passage of a shaped electron wave packet with an electric quadrupole moment in the non-paraxial…
Smith-Purcell radiation of a vortex electron
Andrey Pupasov-Maksimov, Dmitry Karlovets
We study Smith-Purcell radiation from a conducting grating generated by a vortex electron with an orbital angular momentum , described as a generalized Laguerre-Gaussia…
Reply to Comment on "Nonlinear quantum effects in electromagnetic radiation of a vortex electron" by A. Karnieli, R. Remez, I. Kaminer, et al
D. V. Karlovets, A. M. Pupasov-Maksimov
We argue that while the experiment of Remez et al. is interesting and its conclusions may well be correct, the observed lack of dependence of the measured distributions on the elec…
Non-linear quantum effects in electromagnetic radiation of a vortex electron
D. V. Karlovets, A. M. Pupasov-Maksimov
There is a controversy of how to interpret interactions of electrons with a large spatial coherence with light and matter. When such an electron emits a photon, it can do so either…
Relativistic corrections to the algebra of position variables and spin-orbital interaction
Alexei A. Deriglazov, Andrey M. Pupasov-Maksimov
In the framework of vector model of spin, we discuss the problem of a covariant formalism \cite{Pomeranskii1998} concerning the discrepancy between relativistic and Pauli Hamiltoni…
Single- and coupled-channel radial inverse scattering with supersymmetric transformations
Daniel Baye, Jean-Marc Sparenberg, Andrey M Pupasov-Maksimov +1
The present status of the coupled-channel inverse-scattering method with supersymmetric transformations is reviewed. We first revisit in a pedagogical way the single-channel case,…
