SCL Seminar by Milena Simić

You are cordially invited to the SCL seminar of the Center for the Study of Complex Systems, which will be held on Thursday, 14 November 2024 at 14:00 in the library reading room “Dr. Dragan Popović" of the Institute of Physics Belgrade. The talk entitled

Non-adiabatic couplings as a stabilization mechanism in long-range Rydberg molecules

will be given by Milena Simić (Max Planck Institute for the Physics of Complex Systems, Dresden, Germany). The abstract of the talk:

Quantum reflection is a phenomenon where a quantum particle reflects off of a step-like potential remaining bound. This behavior is exhibited in ultralong-range Rydberg molecules, which abound with almost step-like drops at points where potential curves narrowly avoid each other. Despite such a potential landscape, there are numerous resonance states bound by quantum reflection, within Born-Oppenheimer approximation. However, when potential curves come close to each other, they become coupled, leading to significant non-adiabatic couplings. Their influence on molecular binding has been only recently studied in our work, and will be the main focus of this talk, which will start with a broad introduction to the Rydberg atoms and molecules.
