SUMMARY:Workshop / Seminar:CM-AMO Seminar | Berry Phase Enforced Spinor Pairing Order
DESCRIPTION:We introduce a class of topological pairing orders characterized by a half-integer pair monopole charge\, leading to Berry phase enforced half-integer partial wave symmetry. This exotic spinor order emerges from pairing between Fermi surfaces with Chern numbers differing by an odd integer. Using tight-binding models\, we demonstrate spinor superconducting orders with monopole charges \pm 1/2\, featuring a single gap node and nontrivial surface states. Additionally\, the superfluid velocity follows a fractionalized Mermin-Ho relation in spatially inhomogeneous pairing orders. The concept extends to spinor density waves and excitons.
