Relativistic Quantum Chaos in Neutrino Billiards
arXiv:2604.13003v3 Announce Type: replace-cross Abstract: Neutrino billiards serve as a model system for the study of aspects of relativistic quantum chaos. These are relativistic quantum billiards consisting of a spin-1/2 particle which is confined to a planar domain by imposing boundary conditions on the spinor components which were proposed in [Berry and Mondragon, {\it Proc. R. Soc.} A {\bf 412}, 53 (1987)]. We review their general features and the properties of neutrino billiards with shapes of billiards with integrable dynamics. Furthermore, we review the features of two neutrino billiards with the shapes of billiards generating a chaotic dynamics, whose nonrelativistic counterpart exhibits particular properties. Finally we briefly discuss possible experimental realizations of relativistic quantum billiards based on graphene billiards, that is, finite-size sheets of graphene.
