A complete classification of threshold properties for one-dimensional discrete Schrödinger operators
Kenichi Ito, Arne Jensen
We consider the discrete one-dimensional Schrödinger operator , where and is a self-adjoint operator on with a…
Metastable states when the Fermi Golden Rule constant vanishes
Horia D. Cornean, Arne Jensen, Gheorghe Nenciu
Resonances appearing by perturbation of embedded non-degenerate eigenvalues are studied in the case when the Fermi Golden Rule constant vanishes. Under appropriate smoothness prope…
Representability Conditions by Grassmann Integration
Volker Bach, Hans Konrad Knörr, Edmund Menge
Representability conditions on the one- and two-particle density matrix for fermion systems are formulated by means of Grassmann integrals. A positivity condition for a certain kin…
On the steady state correlation functions of open interacting systems
Horia D. Cornean, Claude-Alain Pillet, Valeriu Moldoveanu
We address the existence of steady state Green-Keldysh correlation functions of interacting fermions in mesoscopic systems for both the partitioning and partition-free scenarios. U…
