A First-Order Phase Transition in Spin-Imbalanced BCS Theory of Superconductivity
Marius Lemm, Barbara Roos
We study a translation-invariant BCS functional of superconductivity for a system of spin- fermions with spin-dependent chemical potentials, . Numerical work of Ca…
Is rapid mixing stable?
Jordi A. Montañà-López, Barbara Roos, Sebastian Stengele +2
Several physically interesting Lindbladians, such as those describing generic open quantum system models as well as engineered state preparation processes, are often rapidly mixing…
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{H…
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…
