标题： TASI Lectures on Holographic Space-Time, SUSY and Gravitational Effective Field Theory

摘要： 我主张，在量子引力中，传统的场论真空态概念是不成立的。 这些论点使用了引力有效场论以及来自弦理论的结果，特别是AdS/CFT对偶性。 同一低能引力场方程的不同解对应于不同的量子系统，而不是同一系统中的不同状态。 然后我引入了{\it 全息时空}，这是一个基于全息原理的准局部量子力学构造。 我主张在渐近平直时空中的量子引力模型将严格具有超庞加莱对称性，因为这种系统的全息时空的自然变量是无质量超粒子的自由度。 该形式主义导致了一个非奇异的量子大爆炸宇宙学，在这个模型中，渐近未来必须是一个德西特空间，其宇宙学常数(c.c.)由宇宙学初始条件决定。 在未来，它也近似具有SUSY性质，其引力微子质量为$K \Lambda^{1/4}$。 显示英文摘要

摘要： I argue that the conventional field theoretic notion of vacuum state is not valid in quantum gravity. The arguments use gravitational effective field theory, as well as results from string theory, particularly the AdS/CFT correspondence. Different solutions of the same low energy gravitational field equations correspond to different quantum systems, rather than different states in the same system. I then introduce {\it holographic space-time} a quasi-local quantum mechanical construction based on the holographic principle. I argue that models of quantum gravity in asymptotically flat space-time will be exactly super-Poincare invariant, because the natural variables of holographic space-time for such a system, are the degrees of freedom of massless superparticles. The formalism leads to a non-singular quantum Big Bang cosmology, in which the asymptotic future is required to be a de Sitter space, with cosmological constant (c.c.) determined by cosmological initial conditions. It is also approximately SUSic in the future, with the gravitino mass $K \Lambda^{1/4}$.
