论文摘要
我们预测掺杂$δ_{p} $的声音异常，其中伪模在孔掺杂的蛋饼的正常状态下结束。我们的预测基于使用集群动态平均场理论的二维可压缩哈伯德模型。我们发现声音速度的尖锐异常（DIPS）是掺杂和相互作用的函数。这些倾角是超临界现象的签名，是由于电子过渡而没有对称性损坏超导圆顶的。如果经过实验验证，这些签名可能有助于解决伪群的性质的基本问题 - 将其起源指定为莫特物理学和导致的短距离相关性。
We predict sound anomalies at the doping $δ_{p}$ where the pseudogap ends in the normal state of hole-doped cuprates. Our prediction is based on the two-dimensional compressible Hubbard model using cluster dynamical mean-field theory. We find sharp anomalies (dips) in the velocity of sound as a function of doping and interaction. These dips are a signature of supercritical phenomena, stemming from an electronic transition without symmetry breaking below the superconducting dome. If experimentally verified, these signatures may help to solve the fundamental question of the nature of the pseudogap -- pinpointing its origin as due to Mott physics and resulting short-range correlations.
