Electronic states of nodal-line semimetal under magnetic field

Tóm tắt

Nodal-line semimetals (NLSMs) have attracted significant attention due to their unique electronic properties arising from one-dimensional band degeneracies in momentum space. This study, we investigate the electronic states of NLSMs under the influence of a uniform external magnetic field. By formulating and solving the Schrödinger equation, we derive the wave functions and energy spectra of the system, taking into account the spin-orbit coupling effect and symmetry considerations. Numerical methods are employed to analyze the energy dispersion and spatial distribution of electronic states under varying magnetic field strengths. The results reveal the evolution of localized states, spin splitting, and magneto-dependent conductivity, offering insights into magneto-optical and transport behaviors. These findings provide a theoretical foundation for future studies on the optical properties of NLSMs in the presence of a magnetic field.
