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…
Tunnelling of Polarized Electrons in Magnetic Wires
D. Schmeltzer
We investigate the tunnelling between an electronic gas with two different velocities and a regular metal. We find that at the interface between the…
Transport of a Luttinger liquid in the presence of a time dependent impurity
D. Schmeltzer
We show that the macroscopic current and charge can be formulated as a Quantum Mechanical zero mode problem. We find that the current is given by the velocity operator of a particl…
Analytic approach to the one-dimensional spin-Peierls system in the entire frequency range
Ping Sun, D. Schmeltzer, A. R. Bishop
We use the two cut-off renormalization group (RG) method to study the spin-Peierls model in one-dimension for the entire phonon frequency range. We integrate out the phonon and sol…
