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…
Elko as an inflaton candidate
Xinglong Chen, Cheng-Yang Lee, Yanjiao Ma +3
Elko is a spin-half fermion with a two-fold Wigner degeneracy and Klein-Gordon dynamics. In this paper, we show that in a spatially flat FLRW space-time, slow-roll inflation can be…
Equivalence of regular spinor fields
Cheng-Yang Lee
In the Lounesto classification, there are three types of regular spinors. They are classified by the condition that at least one of the scalar or pseudo scalar norms are non-vanish…
Mass dimension one fermions in FLRW space-time
Cheng-Yang Lee, Haomin Rao, Wenqi Yu +1
Cosmelkology is the study of Elko in cosmology. Elko is a massive spin-half field of mass dimension one. Elko differs from the Dirac and Majorana fermions because it furnishes the…
