Z_2 Gauge Theory of Electron Fractionalization in the t,t'-J Model
D. Schmeltzer, A. R. Bishop
We consider a strongly correlated "t,t'-J" spin model with a positive uniaxial anisotropy. We show that in 2+1 dimensions, this model is equivalent to spin-charge excitations coupl…

Polarized Magnetic Wire Induced by Tunneling Through a Magnetic Impurity
D. Schmeltzer, A. R. Bishop, A. Saxena +1
Using the zero mode method we compute the conductance of a wire consisting of a magnetic impurity coupled to two Luttinger liquid leads characterized by the Luttinger exponent $α(\…

Damping of Nodal Fermions Caused by a Dissipative Mode
D. Schmeltzer
Using a superconductor in 2+1 dimensions we show that the Nambu Goldstone fluctuations are replaced by dissipative excitations. We find that the nodal quasi-particl…
