    "abstract": "Classically, the dynamics of the chiral oscillator (CO) may be described by\nthe Landau model (LM) through a well established mathematical procedure known\nas duality mapping. In this letter we show how this duality is broken in\nquantum mechanics due to the presence of a $Z_2$-anomaly in the CO. We give the\ntheoretical basis for an experimental setup displaying the possibility to\nmeasure this global anomaly using cold Rydberg atoms.",
