SUSY meets pseudo-Hermiticity
Cheng-Yang Lee, Gloria Cecilia de León Morales, Julio Olmos +2
In this work, we construct the simplest pseudo-Hermitian quantum field theory that is supersymmetric. This is the pseudo-Hermitian Wess-Zumino model in the sense that it contains a…
Pseudo-Hermitian QFT: relativistic scattering and symmetry structure
Ruifeng Leng, Cheng-Yang Lee, Siyi Zhou
Unitarity is a cornerstone of quantum theory, ensuring the conservation of probability and information. Although non-Hermitian Hamiltonians are typically associated with open or di…
The anomalous spin-statistics connection arising from pseudo-Hermiticity
Yao Bai, Cheng-Yang Lee, Ruifeng Leng +1
We establish a new spin-statistics theorem for a class of free pseudo-Hermitian quantum field theories whose particles furnish unitary irreducible representations of the Poincaré g…
Wigner multiplets in QFT: from Wigner degeneracy to Elko fields
Cheng-Yang Lee, Ruifeng Leng, Siyi Zhou
We establish the theoretical foundation of the Wigner superposition field, a quantum field framework for spin-1/2 fermions that exhibit a Wigner doublet -- a discrete quantum numbe…
Wigner multiplets in QFT: dark sector and CPT-violating scenarios
Cheng-Yang Lee, Ruifeng Leng, Siyi Zhou
The classification of elementary particles based on unitary irreducible representations of the Poincare group has been a cornerstone of modern Quantum Field Theory (QFT). While the…
Correlators for pseudo Hermitian systems
Yao Bai, Ting-Long Feng, Suro Kim +4
Pseudo-Hermitian system is a class of non-Hermitian system with Hamiltonian satisfying the condition . We develop the in-in and Schwinger Keldysh formalism to c…
