Starting from the d-wave resonating-valence-bond mean-field theory of Kotliar and Liu, we present a new, long-wavelength/low-energy exact, treatment of gauge fluctuations. The result is a theory of gapless fermion quasiparticles coupled to superconducting phase fluctuations. We will discuss the physical implications, and the similarity and differences to a theory of superconductors with phase fluctuations.
从科特里亚尔和刘的d波共振价键平均场理论出发，我们提出了一种新的、长波长/低能量精确的规范涨落处理方法。结果得到了一种无隙费米子准粒子与超导相位涨落耦合的理论。我们将讨论其物理意义，以及与具有相位涨落的超导理论的异同。
