DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QM3/38/">Ind
 icators of quantum chaos and the transition from few- to many-body systems
 </a>\nby Lea Santos (Yeshiva University) as part of Quantum Matter meets M
 aths (IST\, Lisbon)\n\n\nAbstract\nQuantum chaos\, especially when caused 
 by particle interactions\, is closely related with topics of high experime
 ntal and theoretical interest\, from the thermalization of isolated system
 s to the difficulties to reach a localized phase\, and the emergence of qu
 antum scars. In this talk\, various indicators of quantum chaos will be co
 mpared\, including level statistics\, structure of eigenstates\, matrix el
 ements of observables\, out-of-time ordered correlators\, and the correlat
 ion hole (ramp). These indicators are then employed to identify the minimu
 m number of interacting particles required for the onset of strong chaos i
 n quantum systems with short-range and also with long-range interactions.\
