Macroscopic Thermalization for Highly Degenerate Hamiltonians After Slight Perturbation
Barbara Roos, Shoki Sugimoto, Stefan Teufel +2
We say of an isolated macroscopic quantum system in a pure state that it is in macroscopic thermal equilibrium (MATE) if lies in or close to a suitable subspace $\mathcal…

Linear Criterion for an Upper Bound on the Bardeen-Cooper-Schrieffer Critical Temperature
Barbara Roos
Since Bardeen-Cooper-Schrieffer theory of superconductivity is non-linear, it is difficult to study superconducting properties analytically. There is a more tractable linear criter…
