A mixed mean-field/BCS phase with an energy gap at high
N. Ilieva, W. Thirring
We construct a pair potential which in a scaling limit leads to a Hamiltonian that generates co-existing mean-field and superconducting phases. Depending on the relative values of…

The Thirring model 40 years later
N. Ilieva, W. Thirring
Solutions to the Thirring model are constructed in the framework of algebraic QFT. It is shown that for all positive temperatures there are fermionic solutions only if the coupling…
