Exact solution of a 1D many-body system with momentum dependent interactions
Harald Grosse, Edwin Langmann, Cornelius Paufler
We discuss a 1D many-body model of distinguishable particles with local, momentum dependent two-body interactions. We show that the restriction of this model to fermions correspond…

Renormalisation of ϕ^4-theory on noncommutative R^4 in the matrix base
Harald Grosse, Raimar Wulkenhaar
We prove that the real four-dimensional Euclidean noncommutative ϕ^4-model is renormalisable to all orders in perturbation theory. Compared with the commutative case, the bare acti…
