Collective dispersion relations for the 1D interacting two-component Bose and Fermi gases
M. T. Batchelor, M. Bortz, X. W. Guan +1
We investigate the elementary excitations of charge and spin degrees for the 1D interacting two-component Bose and Fermi gases by means of the discrete Bethe ansatz equations. Anal…
Theoretical analysis of the double spin chain compound KCuCl_3
M. T. Batchelor, X. W. Guan, N. Oelkers
We investigate thermal and magnetic properties of the double spin chain compound KCuCl_3 via an exactly solved ladder model with strong rung interaction. Results from the analysis…
Exact results for the 1D interacting mixed Bose-Fermi gas
M. T. Batchelor, M. Bortz, X. W. Guan +1
The exact solution of the 1D interacting mixed Bose-Fermi gas is used to calculate ground-state properties both for finite systems and in the thermodynamic limit. The quasimomentum…
Exact results for the 1D interacting Fermi gas with arbitrary polarization
M. T. Batchelor, M. Bortz, X. W. Guan +1
We investigate the 1D interacting two-component Fermi gas with arbitrary polarization. Exact results for the ground state energy, quasimomentum distribution functions, spin velocit…
