The Binding Energy, Spin-Excitation Gap, and Charged Gap in the Boson-Fermion Model

Autor: Han Ru-Qi, Yang Kai-Hua, Tian Guang-Shan

Publikováno v: Communications in Theoretical Physics. 40:215-220

In this paper, by applying a simplified version of Lieb's spin-reflection-positivity method, which was recently developed by one of us [G.S. Tian and J.G. Wang, J. Phys. A: Math. Gen. 35 (2002) 941], we investigate some general properties of the boso

Journal. Supplement, vol. 80, pp. SB030 .

We have investigated how a magnetic field applied perpendicular to the CuO2 planes of the near-optimally hole-doped high-temperature superconductor La1.855Sr0.145CuO4 (Tc ≈ 36 K) influences the low-energy magnetic excitation spectrum. Our detailed
