In physics, Berry connection and Berry curvature are related concepts which can be viewed, ... If the surface is a closed manifold, the boundary term vanishes, ...
Behavior of the curvature function (Berry connection) for the Kitaev model (top panel) as a function of a parameter change in parameter space (bottom panel). The vertical red lines depict topological phase boundaries. Across the topological phase transitions, the Berry connection diverges and flips sign around the high-symmetry points k=0.
Trigonal bipyramidal molecular shape ax = axial ligands (on unique axis) eq = equatorial ligand (in plane perpendicular to unique axis). The Berry mechanism, or Berry pseudorotation mechanism, is a type of vibration causing molecules of certain geometries to isomerize by exchanging the two axial ligands (see the figure) for two of the equatorial ones.
The phenomenon was independently discovered by S. Pancharatnam (1956), [2] in classical optics and by H. C. Longuet-Higgins (1958) [3] in molecular physics; it was generalized by Michael Berry in (1984). [4] It is also known as the Pancharatnam–Berry phase, Pancharatnam phase, or Berry phase.
Sir Michael Victor Berry (born 14 March 1941) is a British theoretical physicist. He is the Melville Wills Professor of Physics (Emeritus) at the University of Bristol . He is known for the Berry phase , a phenomenon observed in both quantum mechanics and classical optics , as well as Berry connection and curvature .

A manifold is asymptotically simple if it admits a conformal compactification ~ such that every null geodesic in has future and past endpoints on the boundary of ~.. Since the latter excludes black holes, one defines a weakly asymptotically simple manifold as a manifold with an open set isometric to a neighbourhood of the boundary of ~, where ~ is the conformal compactification of some ...
