In this paper we examine the consequences of spin-charge separation on superconductivity. We show that a superconductor with spin-charge separation is a strongly phase-disordered superconductor which is a diamagnetic metal with Drude-like optical conductivity. With a few phenomenological assumptions we argue that this unusual state may correspond to the “upper" pseudo-gap phase of several (underdoped) high-Tc cuprates. Vortices with unquantized magnetic flux are predicted to exist in this unusual state of matter.
