摘要:

重新评估利用相干态变分方法在大N极限下研究无限体积QCD类理论的可行性。描述了一种全新的实现方法,适用于SU(N)晶格规范理论,包括有或无基本表示费米子,在最多四维的立方晶格上。除了各种测试案例外,还展示了在无限二维空间晶格上哈密顿量Yang-Mills理论的初步结果。

英文摘要:

The feasibility of studying, numerically, properties of infinite volume QCD-like theories in the large $N$ limit using coherent state variational methods is reassessed. An entirely new implementation of this approach is described, applicable to SU($N$) lattice gauge theories, with or without fundamental representation fermions, on cubic lattices of up to four dimensions. In addition to various test cases, initial results are presented for Hamiltonian Yang-Mills theory on an infinite two-dimensional spatial lattice.
