27. augustist 1. septembrini 2016 korraldab TÜ Füüsika Instituut Dorpati KonverentsikeskusesXXIII rahvusvahelise Jahn-Telleri efekti sümpoosioni.
Jahn-Telleri sümpoosionite seeria on alguse saanud aastal 1976. Tegemist on unikaalse konverentsiga, kus kohtuvad nii teooria kui rakendustega tegelevad füüsikud ja keemikud. Arutluse all olevateks teemadeks on elektronide ja tuumade liikumiste vastastikmõju molekulides ja kristallides kõdunud energiaga seisundites. Jahn-Telleri efekt, pseudo Jahn-Telleri efekt ning nendega seonduvad elektron-võnkeinteraktsioonid mängivad keskset rolli väga erinevate nähtuste seletamisel nagu spontaanne sümmeetria rikkumine, struktuursed faasisiirded, suur magnettakistus, molekulaarne magnetism, ülijuhtivus fullereenides ning keemilised reaktsioonid pärast soojuslikku või valgusergastust.
Sümpoosioni toimumist toetab Euroopa Liit Euroopa Regionaalarengu Fondi kaudu.

From 27th of August to 1st of September Institute of Physics organizes in Tartu Vibronic Coupling and Electron-Phonon Interactions in Molecules and Crystals: XXIII International Symposium on the Jahn-Teller Effect.
The series of mostly biannual Jahn-Teller symposia started in 1976 and addresses topics involving the coupling between electronic and nuclear motions in molecules and solids in conditions of electronic degeneracy and pseudodegeneracy. The Jahn-Teller effect, pseudo Jahn-Teller effect, and related vibronic coupling and electron-phonon interactions are responsible for structural instabilities and dynamics in polyatomic systems, and play a key role in the explanation of seemingly diverse phenomena, such as spontaneous symmetry breaking, structural phase transitions, colossal magnetoresistance, peculiar molecular magnetism, superconductivity in fullerides, giant permittivity and flexoelectricity, and chemical reactions after thermo- or photoexcitation.
Topics of the symposium include
- Fundamental theory, computation, and experimental observation of vibronic coupling Jahn-Teller (JT), pseudo JT (PJT), and Renner-Teller effects
- Vibronic coupling effects in structural, reactivity, and spectroscopy properties of molecules and clusters, fullerenes and fullerides, graphene, silicene, and related systems
- Conical intersections, geometric phase effects, and nonadiabatic dynamics on intersecting potential energy surfaces; implications in photophysical and decay processes
- Local and cooperative JT and PJT effects and electron-phonon interactions in solids: impurity centers, ferroelectrics, multiferroics, topological insulators, superconductors, spin-orbital and spin-crossover effects
- Further applications of the JT and PJT effects in materials science: spintronics, magnetic-dipolar bistability, molecular magnets, permittivity, flexoelectricity, and electrostriction
Symposium is supported by the European Union through the Regional Development Fund.
