Comparing the Schrödinger and Dirac Descriptions of an Electron in a Uniform Magnetic Field

Revista Brasileira de Ensino de Física
In this article we present a detailed description, using ladder operators, of an electron in a uniform magnetic field evolving under the Schrödinger equation.

A Learning Model with Memory in the Financial Markets

International Journal of Finance &Economics, EarlyView.
ABSTRACT Learning is central to a financial agent's aspiration to gain persistent strategic advantage in asset value maximisation. The implicit mechanism that transforms this aspiration into an observed value gain is the speed of error corrections (demonstrating, an agent's speed of learning) whilst facing increased uncertainty.

Pseudomagnetic Control of Light Waves in the Electrically Tunable Photonic Crystals with Deformation Engineering

Laser &Photonics Reviews, EarlyView.
This work presents a triaxially deformed photonic crystal cavity on the SOI substrate, enabling the localization and resonating of photons via pseudomagnetic fields. Through coupling with Si waveguides and leveraging the thermo‐optic effect, electrically tunable pseudo‐magnetism‐induced optical resonances can be achieved in the photonic integrated ...

Chiral oscillations in quantum field theory

Physics Letters B
Massive fermions produced with definite chirality undergo chiral oscillations. So far, this phenomenon has been mainly described in the framework of single particle relativistic quantum mechanics. In this paper, we present a quantum field theory approach

Spectral Parameter Power Series Representation for Regular Solutions of the Radial Dirac System

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT A spectral parameter power series (SPPS) representation for the regular solution of the radial Dirac system with complex coefficients is obtained, as well as a SPPS representation for the (entire) characteristic function of the corresponding spectral problem on a finite interval. Based on the SPPS representation, a numerical method for solving

Relational Bundle Geometric Formulation of Non‐Relativistic Quantum Mechanics

Fortschritte der Physik, EarlyView.
Abstract A bundle geometric formulation of non‐relativistic many‐particles Quantum Mechanics is presented. A wave function is seen to be a C$\mathbb {C}$‐valued cocyclic tensorial 0‐form on configuration space‐time seen as a principal bundle, while the Schrödinger equation flows from its covariant derivative, with the action functional supplying a ...

A possible mechanism to alter gyromagnetic factor

Results in Physics
Dirac has predicted that the g factor of an electron is strictly equal to 2 in the framework of relativistic quantum mechanics. However, later physicists have found that this factor can slightly deviate from 2 (i.e., the problem of anomalous magnetic ...
