Venue: Seminar Room A 113 (Cripps North Building, CAPT)


Title: Pseudo-Hermitian Quantum Field Theories from First Principles


Abstract:  It is now well established that quantum theories described by non-Hermitian Hamiltonians can exhibit real spectra and a unitary evolution.  The viability of these “pseudo-Hermitian” quantum theories often relies on the invariance of the Hamiltonian under antilinear spacetime symmetries; namely, the combined action of parity and time-reversal transformations.  Spacetime symmetries play a special role in quantum field theory, and this makes the second quantization of pseudo-Hermitian mechanics more intricate.  In this talk, I will describe how self-consistent pseudo-Hermitian quantum field theories can be built from first principles and highlight novel implications for high energy physics phenomenology.
