Self-consistent theory of compact QED3 with relativistic fermions
Matthew J. Case, Babak H. Seradjeh, Igor F. Herbut
We consider three dimensional quantum electrodynamics (cQED3) with massless relativistic fermions coupled to a compact gauge field using a combined perturbative variational approac…
Absence of U(1) spin liquids in two dimensions
Igor F. Herbut, Babak H. Seradjeh, Subir Sachdev +1
Many popular models of fractionalized spin liquids contain neutral fermionic spinon excitations on a Fermi surface, carrying unit charges under a compact U(1) gauge force. We argue…
Theory of strongly phase fluctuating d-wave superconductors and the spin response in underdoped cuprates
Igor F. Herbut
General theory of d-wave quasiparticles coupled to phase fluctuations of superconducting order parameter is discussed. In the charge sector the superfluid density is found to confo…
Theory of spin response in underdoped cuprates as strongly fluctuating d-wave superconductors
Igor F. Herbut, Dominic J. Lee
We study the spin dynamics in underdoped cuprates at low temperatures by considering them as quasi two dimensional d-wave superconductors (dSC) with strong phase fluctuations. An e…
Permanent confinement in the compact QED3 with fermionic matter
Igor F. Herbut, Babak H. Seradjeh
We argue that the compact three dimensional electrodynamics with massless fermions is always confining, in spite of the bare interaction between the magnetic monopoles being render…
Spin-charge separation and recombination in quantum disordered d-wave superconductors
Igor F. Herbut
Some of the results of this paper have been superseded in the meantime. See, cond-mat/0410557.
