Comments on spin-orbit interaction of anyons
P A Horvathy, L. Martina, P. Stichel
The coupling of non-relativistic anyons (called exotic particles) to an electromagnetic field is considered. Anomalous coupling is introduced by adding a spin-orbit term to the Lag…

Enlarged Galilean symmetry of anyons and the Hall effect
P. A. Horvathy, L. Martina, P. Stichel
Enlarged planar Galilean symmetry, built of both space-time and field variables and also incorporating the ``exotic'' central extension is introduced. It is used to describe non-re…

Galilean symmetry in noncommutative field theory
P. A. Horvathy, L. Martina, P. C. Stichel
When the interaction potential is suitably reordered, the Moyal field theory admits two types of Galilean symmetries, namely the conventional mass-parameter-centrally-extended one…
