Mapping of the Calogero-Sutherland model to the Gaussian model
A. M. Tsvelik
The density-density correlation function of the Calogero-Sutherland model is represented as a Fourier transformation of the correlation function of bosonic exponents in the Gaussia…

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…

One-Dimensional Kondo Lattice at Half Filling: Charge Properties
A. M. Tsvelik
The model of Kondo chain with -fold degenerate band of conduction electrons of spin 1/2 at half filling interacting with localized spins is studied. It is shown that due to…
