There are no solutions of the Dirac equation confined to a rectilinear bag with simple MIT bag boundary conditions [1]. A study with spheroidal deformation [2] also produced this result. However, that study also demonstrated that the addition of a chiral phase on the boundary allowed for sensible solutions. We shall present the results of extending this notion to the rectilinear case.
