Accelerated cosmological expansion from pseudo-Hermiticity
Edmund J. Copeland, Andrei Lazanu, Peter Millington +1
We show that a well-studied pseudo-Hermitian field theory composed of two complex scalar fields can generate accelerated cosmological expansion through a novel mechanism. The dynam…

Pseudo-real quantum fields
Maxim N. Chernodub, Peter Millington, Esra Sablevice
We introduce the concept of pseudo-reality for complex numbers. We show that this concept, applied to quantum fields, provides a unifying framework for two distinct approaches to p…

Poincaré symmetries and representations in pseudo-Hermitian quantum field theory
Esra Sablevice, Peter Millington
This paper explores quantum field theories with pseudo-Hermitian Hamiltonians, where PT-symmetric Hamiltonians serve as a special case. In specific regimes, these pseudo-Hermitian…
