CONAN -- the cruncher of local exchange coefficients for strongly interacting confined systems in one dimension
N. J. S. Loft, L. B. Kristensen, A. E. Thomsen +2
We consider a one-dimensional system of particles with strong zero-range interactions. This system can be mapped onto a spin chain of the Heisenberg type with exchange coefficients…

Comparing models for the ground state energy of a trapped one-dimensional Fermi gas with a single impurity
N. J. S. Loft, L. B. Kristensen, A. E. Thomsen +1
We discuss the local density approximation approach to calculating the ground state energy of a one-dimensional Fermi gas containing a single impurity, and compare the results with…
