Vector chiral order in frustrated spin chains
I. P. McCulloch, R. Kube, M. Kurz +3
By means of a numerical analysis using a non-Abelian symmetry realization of the density matrix renormalization group, we study the behavior of vector chirality correlations in iso…
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…
Systematic errors in Gaussian Quantum Monte Carlo and a systematic study of the symmetry projection method
P. Corboz, A. Kleine, F. F. Assaad +3
Gaussian Quantum Monte Carlo (GQMC) is a stochastic phase space method for fermions with positive weights. In the example of the Hubbard model close to half filling it fails to rep…
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…
