Analogue models for T and CPT violation in neutral-meson oscillations - art. no. 096002

Analogue models for CP violation in neutral-meson systems are studied in a general framework. No-go results are obtained for models in classical mecha nics that are nondissipative or that involve one-dimensional oscillators. A complete emulation is shown to be possible for a two-dimensional oscillato r with rheonomic constraints, and an explicit example with spontaneous T an d CPT violation is presented. The results have implications for analogue mo dels with electrical circuits.
