The C Operator in PT-Symmetric Quantum Field Theory Transforms as a Lorentz Scalar
Carl M. Bender, Sebastian F. Brandt, Jun-Hua Chen +1
A non-Hermitian Hamiltonian has a real positive spectrum and exhibits unitary time evolution if the Hamiltonian possesses an unbroken PT (space-time reflection) symmetry. The proof…
Wilson Polynomials and the Lorentz Transformation Properties of the Parity Operator
Carl M. Bender, Peter N. Meisinger, Qinghai Wang
The parity operator for a parity-symmetric quantum field theory transforms as an infinite sum of irreducible representations of the homogeneous Lorentz group. These representations…
Ghost Busting: PT-Symmetric Interpretation of the Lee Model
Carl M. Bender, Sebastian F. Brandt, Jun-Hua Chen +1
The Lee model was introduced in the 1950s as an elementary quantum field theory in which mass, wave function, and charge renormalization could be carried out exactly. In early stud…
A Possible Aoki Phase for Staggered Fermions
C. Aubin, Qinghai Wang
The phase diagram for staggered fermions is discussed in the context of the staggered chiral Lagrangian, extending previous work on the subject. When the discretization errors are…
