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…
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…
Local Magnetic Susceptibility of the Positive Muon in the Quasi 1D S=1/2 Antiferromagnet dichlorobis (pyridine) copper (II)
J. A. Chakhalian, R. F. Kiefl, R. Miller +9
We report muon spin rotation measurements of the local magnetic susceptibility around a positive muon in the paramagnetic state of the quasi one-dimensional spin 1/2 antiferromagne…
