Vector-like Fermion Doubling and Pair-creation on a lattice
She-Sheng Xue
Based on the Pauli principle and Heisenberg uncertainty relationship, we show that the phenomenon of vectorlike fermion-doubling in quantum field theories on a lattice is related t…
An illustration of chiral fermions on a 1+1 dimensional lattice
She-Sheng Xue
The vectorlike doubling of low-energy excitations is in fact a natural consequence of the pair-production around the zero-energy (E=0) due to the quantum field fluctuations of the…
The Emergence of a Heavy Quark Family on a Lattice
She-Sheng Xue
Within the framework of the ``Rome approach'' for a lattice chiral gauge theory, the four-quark interaction with flavour symmetry is included. We analyse spontaneous symmetry break…
External magnetic fields in gauge theories
L. Gamberale, G. Preparata, She-Sheng XUE
A general discussion is presented of the response of a gauge-field system to external magnetic fields, in the light of a theorem due to S. Elitzur. As a result a natural understand…
