摘要：
我们针对一般费米子系统提出了一种在海森堡绘景下表述的定域模型。为此，我们将采用近期提出的形式体系——即所谓的“Raymond-Robichaud”构造，该构造可针对任何满足无信号条件的动力学理论，通过可附着于每个独立子系统的变换等价类，构建出显式定域的模型。通过严格运用费米子的宇称超选择定则，我们展示了该构造如何消除费米子系统在定域态与定域变换的定义方面通常存在的难题。
英文摘要：
We propose a local model for general fermionic systems, which we express in the Heisenberg picture. To this end, we shall use a recently proposed formalism, the so-called "Raymond-Robichaud" construction, which allows one to construct an explicitly local model for any dynamical theory that satisfies no-signalling, in terms of equivalence classes of transformations that can be attached to each individual subsystem. By following the rigorous use of the parity superselection rule for fermions, we show how this construction removes the usual difficulties that fermionic systems display in regard to the definition of local states and local transformations.
