Topic

Neutrons as a tool to surpass Born-Oppenheimer approximation

Presenter:

Dr Petr Čermák, MGML, Charles University, Prague, CZ

Summary

Modern condensed matter physics theories are using several assumptions, allowing to solve quantum mechanical problems otherwise hardly solvable. One of them is Born-Oppenheimer approximation: “we can separate motion of nuclei and motion of electrons”. There exist materials with exotic properties where approximation is no longer valid because nuclei-electron interaction is not negligible. It is extremely challenging to directly see these effects because nuclei are thousand times heavier than electrons. Neutron scattering is probably the only suitable method, thanks to neutron mass and spin...
