标题： Magnetoresistivity in the Antiferromagnetic Hubbard Model

摘要： 我们利用单 Site 动态平均场近似（DMFT）研究了在外加磁场下单带反铁磁（AF）半满 Hubbbard 模型的磁输运性质。特别关注驱动磁电阻行为的机制。我们分析了磁电阻随温度和外加磁场强度的变化关系，为反铁磁体系中磁涨落与输运性质之间的相互作用提供了见解。 显示英文摘要

摘要： We investigate the magnetotransport properties of the half-filled antiferromagnetic (AF) one-band Hubbard model under an external magnetic field using the single-site dynamical mean-field approximation (DMFT). Particular attention is paid to the mechanisms driving the magnetoresistivity behavior. We analyze the dependence of magnetoresistivity on temperature and the strength of the applied magnetic field, providing insights into the interplay between magnetic fluctuations and transport properties in AF systems.
