Ginzburg-Landau equation and vortex liquid phase of Fermi liquid superconductors
Tai-Kai Ng, Wai-Tak Tse
Abstract
In this paper we study the Ginzburg-Landau (GL) equation for Fermi liquid superconductors with strong Landau interactions F0 and F1. We show that Landau interactions renormalize two parameters entering the GL equation leading to renormalization of superfluid density and separation of length and energy scales for amplitude and phase fluctuations. The separation of energy/length scales for amplitude and phase fluctuations in term leads to unconventional (2D) KT transition and vortex liquid phase. Application of the GL equation to describe underdoped high-Tc cuprates is being discussed.
