在热相位涨落的情况下,研究了欠掺杂铜氧化物赝能隙相费米弧现象的起源。引入一个具有d波结构的XY型晶格模型来描述铜氧化物中的相位涨落效应。在费米面的Kosterlitz-loss(KT)转变温度(TKT)以上,发现谱函数A(k,ω = 0)中突然出现一个尖锐的脊状结构. A(k,ω = 0)中的这种脊状结构在其温度依赖性和动量空间中的形状方面与所观察到的费米弧现象非常相似。这些结果为欠掺杂铜氧化物超导转变的KT转变性质提供了更有力的证据。
The origin of the Fermi arc phenomenon in the pseudogap phase of the underdoped cuprates is studied in the thermal phase fluctuation scenario. An XY-type lattice model with a built in d-wave structure is introduced to describe the phase fluctuation effect in the cuprates. A sharp ridge-like structure in the spectral function A(k, ω = 0) is found to emerge abruptly above the Kosterlitz–Thouless (KT) transition temperature (TKT) on the underlying Fermi surface. This ridge-like structure in A(k, ω = 0) bears a close resemblance to the observed Fermi arc phenomenon in its temperature dependence and shape in the momentum space. These results provide yet more strong evidence for the KT transition nature of the superconducting transition in the underdoped cuprates.
