Aside from as sessing whether black holes are unequivocally described by the Kerr metric \, they may place constraints on the degree of spacetime symmetry. Dependi ng on exactly how a hypothetical departure from the Kerr metric manifests\ , the Carter symmetry\, which implies the integrability of the geodesic eq uations\, may be broken. In this talk\, I will discuss the impact of non-i ntegrability in EMRIs which involve a supermassive compact object with ano malous multipolar structure. After reviewing the features of chaotic pheno mena in EMRIs\, I will argue that non-integrability is precisely imprinted in the gravitational waveform. Explicit examples of non-integrable EMRIs will be discussed\, as well as their role in LISA data analysis.\n\nThis t alk will be based on the following articles:\n\nPhys.Rev.D 102 (2020) 6\, 064041\nPhys.Rev.Lett. 126 (2021) 14\, 141102\n LOCATION:https://researchseminars.org/talk/CENTRA/48/ END:VEVENT END:VCALENDAR
