Ising paramagnons

  title={Ising paramagnons},

Paramagnons are the collective modes that govern the spin response of nearly ferromagnetic conductors. Their interactions with quasiparticles can induce spin-triplet superconductivity, a scenario that may occur in spin-valley coupled two dimensional transition metal dichalcogenides such as 2H-NbSe2. This motivates this work exploring paramagnons in systems with spin split bands due to spin orbit coupling leading to spin-valley coupling. We use both a Kane-Mele-Hubbard model and a tight-binding…

Superconductivity in rhombohedral trilayer graphene.
The observation of superconductivity-manifesting as low- or vanishing resistivity at sub-kelvin temperatures-in crystalline rhombohedral trilayer graphene5,6, a structurally metastable carbon allotrope provides a model system to test competing theoretical models ofsuperconductivity without the complication of modeling disorder, while enabling new classes of field-effect controlled electronic devices based on correlated electron phenomena and ballistic electron transport.
Superconductivity in the vicinity of an isospin-polarized state in a cubic Dirac band
We present a theory of superconducting pairing originating from soft critical fluctuations near isospin-polarized states in rhombohedral trilayer graphene. Using a symmetry-based approach, we
however (for it was the literal soul of the life of the Redeemer, John xv. io), is the peculiar token of fellowship with the Redeemer. That love to God (what is meant here is not God’s love to men)
