Quantum Geometric Unconventional Superconductivity

G Shavit, J Alicea - arxiv preprint arxiv:2411.05071, 2024 - arxiv.org
Coulomb repulsion can, counterintuitively, mediate Cooper pairing via the Kohn-Luttinger
mechanism. However, it is commonly believed that observability of the effect requires …

Ephemeral Superconductivity Atop the False Vacuum

G Shavit, S Nadj-Perge, G Refael - arxiv preprint arxiv:2409.02992, 2024 - arxiv.org
A many body system in the vicinity of a first-order phase transition may get trapped in a local
minimum of the free energy landscape. These so-called false-vacuum states may survive for …

Chiral superconductivity from parent Chern band and its non-Abelian generalization

YQ Wang, ZQ Gao, H Yang - arxiv preprint arxiv:2410.05384, 2024 - arxiv.org
We propose a minimal model starting from a parent Chern band with quartic dispersion that
can describe the spin-valley polarized electrons in rhombohedral tetra-layer graphene. The …
