Ground-state properties of the attractive one-dimensional Bose-Hubbard model
Norman Oelkers, Jon Links
We study the ground state of the attractive one-dimensional Bose-Hubbard model, and in particular the nature of the crossover between the weak interaction and strong interaction re…
Emergent quantum phases in a heteronuclear molecular Bose--Einstein condensate model
Melissa Duncan, Angela Foerster, Jon Links +3
We study a three-mode Hamiltonian modelling a heteronuclear molecular Bose--Einstein condensate. Two modes are associated with two distinguishable atomic constituents, which can co…
The 1D interacting anyon gas: low-energy properties and Haldane exclusion statistics
M. T. Batchelor, X. -W. Guan, N. Oelkers
The low energy properties of the one-dimensional anyon gas with -function interaction are discussed in the context of its Bethe ansatz solution. It is found that the anyonic sta…
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…
Integrable models and quantum spin ladders: comparison between theory and experiment for the strong coupling ladder compounds
M. T. Batchelor, X. -W. Guan, N. Oelkers +1
(abbreviated) This article considers recent advances in the investigation of the thermal and magnetic properties of integrable spin ladder models and their applicability to the phy…
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…
