Boundary Effects on Spectral Properties of Interacting Electrons in One Dimension
Sebastian Eggert, Henrik Johannesson, Ann Mattsson
The single electron Green's function of the one-dimensional Tomonaga-Luttinger model in the presence of open boundaries is calculated with bosonization methods. We show that the cr…

Spin Dynamics of the Triangular Heisenberg Antiferromagnet: A Schwinger Boson Approach
Ann Mattsson
We have analyzed the two-dimensional antiferromagnetic Heisenberg model on the triangular lattice using a Schwinger boson mean-field theory. By expanding around a state with local…
