Abstract

Abstract Within a strongly interacting Fermi liquid framework, we calculatethe effects of the Zeeman energy $\omega_H$ for a finite magnetic field,in a metallic system with a van Hove peak in the density of states,located close to and below the Fermi surface. We find that the chemicalpotential increases with the square of $\omega_H$. We obtain a characteristicquasiparticle scattering rate linear in the maximum of $\omega_H$ and temperature, both in the normal andthe d-wave superconducting state. We predict that ARPES experiments in copperoxides, and related compounds, shouldbe able to elucidate this behavior of the scattering rate, and in particular,the difference between spin up and down electrons.

铜氧化物及相关材料中准粒子散射速率和ARPES的Zeeman依赖性

摘要:在一个强相互作用的费米液体框架内，我们计算了塞曼能量$\omega_H$对有限磁场的影响，在一个状态密度有van Hove峰的金属体系中，位于费米表面附近和下方。我们发现化学势随着$\omega_H$的平方而增加。我们得到了在正常和d波超导状态下，准粒子散射率在最大温度和最大温度下呈线性的特性。我们预测，在铜氧化物和相关化合物中的ARPES实验，应该能够阐明散射率的这种行为，特别是，自旋上下电子之间的差异。

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
