二维格上经典$ϕ^4$理论的完备性

Completeness of classical $ϕ^4$ theory on 2D lattices

Vahid Karimipour, Mohammad Hossein Zarei

摘要:

我们制定了一个量子形式主义的统计力学模型的离散场论的格子,然后表明,离散版本的$ϕ^4$理论的二维正方形格子是完整的,在这个意义上,任何其他离散标量场理论的配分函数的任意相互作用的任意格子可以实现为一个特殊情况下的配分函数这个模型。为了实现这一点,我们最近提出的伊辛模型\cite{quantum formalism}和它的完整性属性\cite{completeness}的连续变量的情况下的量子形式主义。

英文摘要:

We formulate a quantum formalism for the statistical mechanical models of discretized field theories on lattices and then show that the discrete version of $ϕ^4$ theory on 2D square lattice is complete in the sense that the partition function of any other discretized scalar field theory on an arbitrary lattice with arbitrary interactions can be realized as a special case of the partition function of this model. To achieve this, we extend the recently proposed quantum formalism for the Ising model \cite{quantum formalism} and its completeness property \cite{completeness} to the continuous variable case.
