Anyon in an external electromagnetic field: Hamiltonian and Lagrangian formulations
Anyon in an external electromagnetic field: Hamiltonian and Lagrangian formulations
We propose a simple model for a free relativistic particle of fractional spin in 2+1 dimensions. Using the Hamiltonian formulation with the set of constraints, we introduce the electromagnetic interaction of a charged anyon and obtain the Lagrangian. The Casimir operator of the extended algebra, which is the first-class constraint, …
