Anomalous anharmonicity in doped cuprate superconductors
V. Rzhevskii, G. Roepke
Strong nonlinear elastic effects arise due to the Lifshitz transition associated with a change in the Fermi surface topology. It is shown that an electronic contribution to the ela…

Topological gauge invariant variables in QCD
D. Blaschke, V. N. Pervushin, G. Roepke
We suggest that proper variables for the description of non-Abelian theories are those gauge invariant ones which keep the invariance of the winding number functional with respect…

Deuteron formation in nuclear matter within the Faddeev approach
M. Beyer, C. Kuhrts, G. Roepke
We consider deuteron formation in heavy ion collisions at intermediate energies. The elementary reaction rates (Nd -> NNN) in this context are calculated using rigorous Faddeev met…
