What the article says around this equation
g is an angle: dimensionless, periodic, and physically read as “which way the compass points” relative to the hole’s spin axis. carries units of action (joule-seconds), so g/ is dimensionless, as an exponent must be. Nothing about this setup is exotic — a large-spin coherent state pointing along a direction is a textbook carrier of exactly this kind of information [ 10 ] .
