Ground state properties of multi-polaron systems
Rupert L. Frank, Elliott H. Lieb, Robert Seiringer +1
We summarize our recent results on the ground state energy of multi-polaron systems. In particular, we discuss stability and existence of the thermodynamic limit, and we discuss th…
Microscopic Derivation of the Ginzburg-Landau Model
Rupert L. Frank, Christian Hainzl, Robert Seiringer +1
We present a summary of our recent rigorous derivation of the celebrated Ginzburg-Landau (GL) theory, starting from the microscopic Bardeen-Cooper-Schrieffer (BCS) model. Close to…
Symmetry of bipolaron bound states for small Coulomb repulsion
Rupert L. Frank, Elliott H. Lieb, Robert Seiringer
We consider the bipolaron in the Pekar--Tomasevich approximation and address the question whether the ground state is spherically symmetric or not. Numerical analysis has, so far,…
