对“欠掺杂铜氧化物中自旋涨落驱动电荷有序的强耦合批判”一文的答复
Reply to "A strong coupling critique of spin fluctuation driven charge order in underdoped cuprates"
摘要：
我们回复arXiv：1502.02782的作者对铜氧化物中电荷序的自旋涨落方案的批评。arXiv：1502.02782的作者认为，自旋涨落交换不能产生具有观测动量$(Q, 0)/(0, Q)$的电荷序，因为所涉及的一半费米子没有嵌套。我们明确表明，即使在“最坏情况”的情况下，反嵌套的一半费米子存在对电荷秩序的不稳定性。
英文摘要：
We reply to the criticism from the authors of arXiv:1502.02782 of the spin-fluctuation scenario for charge order in the cuprates. The authors of of arXiv:1502.02782 argued that spin-fluctuation exchange cannot give rise to charge order with observed momentum $(Q, 0)/(0, Q)$ due to the absence of nesting for a half of fermions involved. We explicitly show the instability towards charge order exists even in the "worst-case" scenario of anti-nesting for a half of fermions.
