Tao Li, Fan Yang

摘要:

本文提出了铜氧化物超导体中子共振模的Gutzwiller型变分波函数。设计了一种有效的重新加权技术,对由线性叠加的Gutzwiller投影Slater行列式组成的拟议波函数进行变分蒙特卡罗模拟。计算,其中不涉及自由参数,预测定性正确的行为的能量和光谱权重的共振模式作为掺杂的函数。

英文摘要:

A Gutzwiller-type variational wave function is proposed for the neutron resonance mode in the cuprate superconductors. An efficient re-weighting technique is devised to perform variational Monte Carlo simulation on the proposed wave function which is composed of linearly superposed Gutzwiller projected Slater determinants. The calculation, which involves no free parameter, predicts qualitatively correct behavior for both the energy and the spectral weight of the resonance mode as functions of doping.
