Circadian Displacement: Biological Clocks as Temporal Ground State Keepers, Jet Lag as Phase Displacement, and Shift Work as Chronic Temporal Wrong Attractor

The circadian clock is the organism temporal S⁰ system, maintaining correct phase between internal biology and external light-dark cycle. Circadian displacement D(ξ_circadian) is phase error. Jet lag is acute displacement; shift work is chronic wrong attractor. Social jetlag affects 80% of industrial populations. We derive the Circadian Displacement Theorem and show cancer risk, metabolic syndrome, and cardiovascular disease as consequences of high Phi_circadian.
