| dc.description | Nanowire systems featuring Rashba spin–orbit interaction (SOI) offer an exciting avenue for investigating spintronic technologies and quantum computation [1,2]. The Rashba SOI is generated in systems without inversion symmetry, resulting in a coupling between an electron’s spin and its momentum [3,4]. Upon the application of a magnetic field on nanowire systems, it interacts with the spins of the electrons, allowing for the manipulation of their orientations [5,6]. Moreover, in the presence of a magnetic field, the dynamics of electrons within nanowires undergo notable transformations due to the combined influences of spin–orbit coupling and Zeeman splitting [7]. The magnetic field can lead to a division of energy levels that depends on the electron’s spin state, which can be applied in the development of qubits for quantum computing [8]. The fusion of Rashba SOI and magnetic fields provides an expansive field for academic research and technological advancement in condensed matter physics and nanotechnology [9,10]. | |
| dc.description.abstract | We present a theoretical examination of the fractional dynamics of information entropy within a semiconductor nanowire system influenced by Rashba spin–orbit interaction and external magnetic fields. Moreover, we determine the fractional nanowire state through the analytical solution of the fractional Schrödinger equation, considering various initial states of the nanowire system. Our research emphasizes the impact of the fractional order and the interaction parameters on the behavior of information entropy. Our findings reveal that the temporal behavior of information entropy is highly sensitive to any variations in the magnetic field length, the Rashba spin–orbit interaction, and the fractional order parameter. The results demonstrate that these parameters are pivotal in determining the coherence and correlation properties of the nanowire system. Therefore, precise control of these factors paves the way for enhancing entanglement performance and facilitating information transfer in spintronic and quantum communication applications.
