英文摘要:
The induced electronic interactions in (I + 2)-dimensional vector Chem-Simons systems are studied by means of path-integral quantization. We consider four cases: relativistic, and nonrelativistic fermion Maxwell-Chern-Simons models, and relativistic and nonrelativistic fermion Chern-Simons models. It is shown that the Chern-Simons term may induce exotic electronic interactions which can be local or nonlocal and small Chern-Simons coupling may have a considerable effect in some cases.
