Time-Slicing Path-integral in Curved Space [PDF]
Quantum, 2022 Path integrals constitute powerful representations for both quantum and stochastic dynamics. Yet despite many decades of intensive studies, there is no consensus on how to formulate them for dynamics in curved space, or how to make them covariant with ...

Massive Ray-Singer torsion and path integrals
Journal of High Energy Physics, 2022 Zero modes are an essential part of topological field theories, but they are frequently also an obstacle to the explicit evaluation of the associated path integrals.

A compendium of sphere path integrals
Journal of High Energy Physics, 2021 We study the manifestly covariant and local 1-loop path integrals on S d+1 for general massive, shift-symmetric and (partially) massless totally symmetric tensor fields of arbitrary spin s ≥ 0 in any dimensions d ≥ 2.

A tree approach to $p$-variation and to integration [PDF]
, 2008 We consider a real-valued path; it is possible to associate a tree to this path, and we explore the relations between the tree, the properties of $p$-variation of the path, and integration with respect to the path. In particular, the fractal dimension of

Weak values from path integrals
Physical Review Research, 2020 We connect the weak measurements framework to the path integral formulation of quantum mechanics. We show how Feynman propagators can in principle be experimentally inferred from weak value measurements. We also obtain expressions for weak values parsing

Dirac’s Formalism for Time-Dependent Hamiltonian Systems in the Extended Phase Space
Universe, 2021 Dirac’s formalism for constrained systems is applied to the analysis of time-dependent Hamiltonians in the extended phase space. We show that the Lewis invariant is a reparametrization invariant, and we calculate the Feynman propagator using the extended

Relativistic Path Integrals [PDF]
Progress of Theoretical Physics, 1979 Summary: An elementary theory of relativistic path integrals is developed in the Lorentz space. A path integral for a Dirac electron is formulated, in which the perturbation expansion is shown to give the same rules as those given in the more usual formulation of field theory. A geometric feature of path integrals is investigated by using Weyl's theory

Microcanonical path integrals and the holography of small black hole interiors
Journal of High Energy Physics, 2018 We use a microcanonical path integral closely related to that introduced by Brown and York in 1992 to add new entries to the AdS/CFT dictionary concerning the interiors of small black holes.
