Title: Ground state energy of a low-density fermi gas in 1D

Abstract: I will discuss some topics that are relevant to 1-dimensional fermions with strong, repulsive 2-body interactions. Contrary to the 2 and 3d cases, this can be thought of as a low-density limit. In the spin-1/2 case, the Heisenberg antiferromagnet appears in the effective Hamiltonian, even if the particles live in an interval. This is joint work with Johannes Agerskov and Jan Philip Solovej.
