Self-adjoint extension approach for singular Hamiltonians in (2+1) dimensions
Vinicius Salem, Ramon F. Costa, Edilberto O. Silva +1
In this work, we review two methods used to approach singular Hamiltonians in (2+1) dimensions. Both methods are based on the self-adjoint extension approach. It is very common to…

Symplectic Dirac Equation
R. G. G. Amorim, S. C. Ulhoa, Edilberto O. Silva
Symplectic unitary representations for the Poincaré group are studied. The formalism is based on the noncommutative structure of the star-product, and using group theory approach a…
