Local stability of ground states in locally gapped and weakly interacting quantum spin systems
Joscha Henheik, Stefan Teufel, Tom Wessel
Based on a result by Yarotsky (J. Stat. Phys. 118, 2005), we prove that localized but otherwise arbitrary perturbations of weakly interacting quantum spin systems with uniformly ga…

The BCS Energy Gap at High Density
Joscha Henheik, Asbjørn Bækgaard Lauritsen
We study the BCS energy gap in the high-density limit and derive an asymptotic formula, which strongly depends on the strength of the interaction potential on the Fermi sur…

The BCS Critical Temperature at High Density
Joscha Henheik
We investigate the BCS critical temperature in the high-density limit and derive an asymptotic formula, which strongly depends on the behavior of the interaction potential $V…
