parameter space: tex2html_wrap102

tex2html_wrap103 = wave function

loop, tex2html_wrap104

vary slowly around the loop

tex2html_wrap105

where tex2html_wrap106

This means that the berry connection is: tex2html_wrap107 .

The phase is non-zero if you have nontrivial holonomy or curvature.

tex2html_wrap108 = curvature of bundle
