We investigate the recently discovered multiple superconducting states in rhombohedral graphene quarter metal. We demonstrate that one of these states features a single-spin, single-valley, single-band, single-Fermi-pocket parent state and is most likely a chiral topological pair-density wave, characterized by an ultra-small Fermi pocket and an ultra-large pairing momentum. This novel state exhibits three defining features: a 2D periodic modulation of the pairing phase compatible with the threefold symmetry; unpaired Majorana zero modes localized at edges, vortices, and pairing-phase dislocations; and an anomalous spin-polarized intrinsic superconducting diode effect.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Theory of Metallic Conduction
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.
