洛仑兹对称性破坏与朗道能级的模拟

Lorentz symmetry violation and an Analog of Landau levels

E. Passos, L. R. Ribeiro, C Furtado, J. R. Nascimento

摘要:

在洛伦兹违反扩展电动力学的背景下,我们研究了一个系统的朗道量子化的模拟,其中中性粒子在电磁场和一个恒定的四矢量,打破洛伦兹对称性的存在下移动。用Dirac旋量的Foldy-Wouthuysen变换得到了与该系统相关的非相对论性哈密顿量。得到了类时和类空参数洛仑兹破缺矢量的简并能谱。从超对称量子力学的角度分析了回旋加速器旋转方向与能量的关系。

英文摘要:

Within the context of Lorentz violating extended electrodynamics, we study an analog of Landau quantization for a system where a neutral particle moves in the presence of an electromagnetic field and a constant four-vector that breaks Lorentz symmetry. The nonrelativistic Hamiltonian associated to this system is obtained using the Foldy-Wouthuysen transformation for a Dirac spinor. The degenerated energy spectrum is obtained for a time-like and a space-like parameter Lorentz-breaking vector. The energy dependence of the cyclotron rotation direction in terms of supersymmetric quantum mechanics is analyzed.
