DESCRIPTION:Abstract:A quantum system is open if it interacts with the ext
 ernal environment. This interaction typically induces dissipation and deco
 herence on the open system\, dynamical effects that cannot be captured by 
 a Schrödinger equation. In order to model them properly\, one can adopt t
 wo different strategies: either a quantum dissipative dynamics is postulat
 ed\, based on structural requirements and physical intuition\, or the envi
 ronment is included explicitly in the description and one tries to derive 
 an (approximate) dissipative dynamics for the open system from the global 
 Hamiltonian evolution.In this talk\, I will briefly comment on the first a
 pproach\, mentioning the well-known GKSL theorem that can be used as a gui
 de to construct phenomenological models\, but I will mostly focus on the s
 econd approach. In particular\, analyzing the prototypical example of a fi
 nite-level quantum system interacting with a free Bose gas\, I will discus
 s the main ideas and mathematical tools used to rigorously derive effectiv
 e open systems dynamics in suitable regimes (e.g. ultrastrong coupling).\n
