辛费米子的洛伦兹对称量子场论

Lorentz Symmetric Quantum Field Theory for Symplectic Fermions

Dean J. Robinson, Eliot Kapit, Andre LeClair

摘要:

对2+1维自旋半辛费米子导出了具有洛伦兹对称性的自由量子场论。特别是,我们表明,费米子自旋半场可以在一个自由的理论与克莱因-戈登拉格朗日正则量子化。这个理论被证明具有一个一致的自由量子场论所需的所有属性,即因果关系,幺正性,坚持自旋统计定理,CPT对称性,和厄米性和正定性的哈密顿量。自由理论的整体对称性是Sp(4)$\simeq$ SO(5)。可能的相互作用理论的伪厄米和厄米品种,然后简要审查。

英文摘要:

A free quantum field theory with Lorentz symmetry is derived for spin-half symplectic fermions in 2+1 dimensions. In particular, we show that fermionic spin-half fields may be canonically quantized in a free theory with a Klein-Gordon Lagrangian. This theory is shown to have all the required properties of a consistent free quantum field theory, namely causality, unitarity, adherence to the spin-statistics theorem, CPT symmetry, and the Hermiticity and positive definiteness of the Hamiltonian. The global symmetry of the free theory is Sp(4) $\simeq$ SO(5). Possible interacting theories of both the pseudo-Hermitian and Hermitian variety are then examined briefly.
