Excitations in two-component Bose-gases
Adrian Kleine, Corinna Kollath, Ian P. McCulloch +2
In this paper, we study a strongly correlated quantum system that has become amenable to experiment by the advent of ultracold bosonic atoms in optical lattices, a chain of two dif…

Spin-charge separation in two-component Bose-gases
A. Kleine, C. Kollath, I. McCulloch +2
We show that one of the key characteristics of interacting one-dimensional electronic quantum systems, the separation of spin and charge, can be observed in a two-component system…
