A Generally Covariant Theory of Quantized Dirac Field in de Sitter Spacetime
Sze-Shiang Feng, Mogus Mochena
As a sequel to our previous work\cite{Feng2020}, we propose in this paper a quantization scheme for Dirac field in de Sitter spacetime. Our scheme is covariant under both general t…
A Generally Covariant Theory of Quantized Real Klein-Gordon Field in de Sitter Spacetime
Sze-Shiang Feng
We propose in this paper a quantization scheme for real Klein-Gordon field in de Sitter spacetime. Our scheme is generally covariant with the help of vierbein, which is necessary u…
Implication of Spatial and Temporal Variations of the Fine-Structure Constant
Sze-Shiang Feng, Mu-Lin Yan
Temporal and spatial variation of fine-structure constant in cosmology has been reported in analysis of combination Keck and VLT data. This paper studies this…
Graphene in external fields
Sze-Shiang feng, Mogus Mochena
A general discussion of graphene in external electromagnetic field is provided. In general, the formulation is not Lorentz invariant because of Zeeman energy. But it can be restore…
A low temperature derivation of spin-spin exchange in Kondo lattice model
Sze-Shiang Feng, Mogus Mochena
Using Hubbard-Stratonovich transformation and drone-fermion representations for spin-1/2 and for spin-3/2, which is presented for the first time, we make a path-integral formulatio…
New superconducting states in the Hubbard model
Sze-Shiang Feng, Bin Wang, Elcio Abdalla
By acting on the excited states at half-filling in the positive- Hubbard model with the -pairing operators, we found some new superconducting states in the Hubbard model away…
