Abstract: In physics it i s always desirable to identify universal phenomena that apply to many diff erent physical systems with a simple law owing to a minimal set of paramet ers. In 1970\, Vitaly V. Efimov theoretically predicted in the context of nuclear physics\, the existence of a set of stable quantum states of parti cle triplets when the pairwise two- body constituents alone are unstable. The first confirmation of this counter-intuitive phenomenon occurred in 20 06 by an experimental team at the University of Innsbruck in Austria who o bserved the Efimov states in an ultracold gas of Cs atoms. Since then\, ma ny theoretical and/or experimental proposals showcased the universal aspec ts of the Efimov states in the context of nuclear\, atomic\, or condensed matter physics. Therefore\, in this colloquium I will present my recent th eoretical efforts to extend the concept of universality of the Efimov phys ics. In particular\, in the context of ultracold atomic physics I will dis cuss the few-body collisional aspects of mass-imbalanced systems and the c orresponding emergent Efimov physics.
Short bio: Dr. Panagiotis Giannakeas in 2008 completed his diploma studies in physi cs from the University of Athens\, Greece. In 2013\, he received his PhD f rom the University of Hamburg\, Germany\, under the supervision of Prof. P eter Schmelcher. Then\, he continued as a postdoctoral research associate at Purdue University\, Indiana\, USA\, in the group of Prof. Chris H. Gree ne. In 2017\, he started at the Max Planck Institute for the physics of co mplex systems in Dresden as a guest scientist initially and since 2020 con tinue as a staff scientist in the division of finite systems under the sup ervision of Prof. Jan-Michael Rost.
