Together with some of his collaborators, he investigated how the property of a topological defect would be changed in non-local theory. As a concrete example, he considers a domain wall and is able to find explicit analytic solutions in some regime and/or perturbatively despite the complexity of non-linear infinite-order differential equations. From the stress-energy tensor, he estimates the energy density, and shows that nonlocal effects make the width of the domain wall thinner, and the energy per unit area smaller as compared to the local case.Together with some of his collaborators, under very reasonable assumptions, he derived quantum-gravitational corrections to the famous Bekenstein bound which limits the amount of energy/information that can be stored inside a certain radius.

连同他的一些合作者，他调查了如何财产的拓扑缺陷将改变非本地理论。作为一个具体的例子，他认为一个域墙，并能够找到明确的解析解在某些制度和/或扰动，尽管复杂的非线性无限阶微分方程。从应力-能量张量，他估计了能量密度，并表明非局域效应使畴壁的宽度变薄，与局域情况相比，单位面积的能量更小。他与他的一些合作者一起，在非常合理的假设下，导出了对著名的贝肯斯坦束缚的量子引力修正，该束缚限制了一定半径内可以存储的能量/信息量。
