SO(5)-Symmetric Description of the Low Energy Sector of a Ladder System
David G. Shelton, David Sénéchal
We study a system of two Tomonaga-Luttinger models coupled by a small transverse hopping (a two-chain ladder). We use Abelian and non-Abelian bosonisation to show that the strong c…

An Effective Theory for Midgap States in Doped Spin Ladder and Spin-Peierls Systems: Liouville Quantum Mechanics
David G. Shelton, Alexei M. Tsvelik
In gapped spin ladder and spin-Peierls systems the introduction of disorder, for example by doping, leads to the appearance of low energy midgap states. The fact that these strongl…

Superconducting Instability in a 1D lattice of Berry Phase Molecules
D. Shelton, A. M. Tsvelik
We study the 1D model of conduction electrons interacting with local vibronic modes. States in the conduction band are two-fold degenerate both in orbital index and spin. It is sho…
