Web1 PATH INTEGRALS 1 Path Integrals 1.1 The Canonical Path Integral Our story begins with single-particle quantum mechanics in one dimension. The Hilbert space is H= L2(R), and the system is governed by a self-adjoint Hamiltonian operator H^. We work in the Heisenberg picture, where observables O^ evolve in time according to d dt O^(t) = i[H;^ O ... WebThe general idea of using triangulations to study the Gravitational Path Integral (3) is as follows. We consider a ( nite set of) triangular (simplicial) n+1-dimensional building block(s) and impose a at metric on them. This means that all metric properties of these building blocks are encoded in the lengths of its one-dimensional edges.
WebThe Euclidean quantum gravity is reviewed and a new class of zero action approximate stationary points to the path integral is found. These have arbitrary topology associated with infinitensimal regions but are otherwise metrically flat. It is also argued that topological couplings must be included in the action.

WebSep 18, 2024 · Our motivation is to understand whether some form of averaging is essential for the boundary theory, if we wish to describe the bulk quantum gravity path integral of this two dimensional example. The analysis hence, is in a spirit similar to the recent studies of Jackiw-Teitelboim (JT)-gravity.
WebJun 4, 2024 · In this paper we study Kernel and Feynman Path Integrals in the framework of a GUP that admits a minimal length and a maximal momentum. We work in the quasi-space representation by adopting maximally localized states in position space.
