Role of spinon and spinon singlet pair excitations on phase transitions in superconductors
arXiv:cond-mat/0305385 · doi:10.1103/PhysRevB.69.014504
Abstract
We examine the roles of massless Dirac spinon and spin singlet pair excitations on the phase transition in superconductors. Although the massless spinon excitations in the presence of the spin singlet pair excitations do not alter the nature of the phase transition at , that is, the XY universality class, they are seen to induce an additional attractive interaction potential between vortices, further stabilizing vortex-antivortex pairs at low temperature for lightly doped high samples.
