摘要:

哈密顿光阵面量子场论构成了自束缚系统不变质量和关联部分子振幅的非微扰解的框架。通过选择光前规范和采用基函数表示,我们得到了一个大的稀疏的规范理论质量本征态的哈密顿矩阵,它可以用核多体理论的从头算无核方法求解.在连续极限,即无限矩阵极限中恢复全协方差。我们概述了我们的方法,并讨论了计算的挑战。

英文摘要:

Hamiltonian light-front quantum field theory constitutes a framework for the non-perturbative solution of invariant masses and correlated parton amplitudes of self-bound systems. By choosing light-front gauge and adopting a basis function representation, we obtain a large, sparse, Hamiltonian matrix for mass eigenstates of gauge theories that is solvable by adapting the ab initio no-core methods of nuclear many-body theory. Full covariance is recovered in the continuum limit, the infinite matrix limit. We outline our approach and discuss the computational challenges.
