A path-integral approach to Bayesian inference for inverse problems using the semiclassical approximation
We demonstrate how path integrals often used in problems of theoretical physics can be adapted to provide a machinery for performing Bayesian inference in function spaces. Such inference comes about naturally in the study of inverse problems of recovering continuous (infinite dimensional) coefficient functions from ordinary or partial differential equations (ODE, PDE), a problem which is typica...
متن کاملPath Integral Approach to Noncommutative Spacetimes
We propose a path integral formulation of noncommutative generalizations of spacetime manifold in even dimensions, characterized by a length scale λP . The commutative case is obtained in the limit λP = 0. PACS numbers: 04.60.Gw, 04.60.-m, 02.40-k. ∗E-mail: [email protected]
متن کاملPath integral approach to no-Coriolis approximation in heavy-ion collisions.
We use the two time influence functional method of the path integral approach in order to reduce the dimension of the coupled-channels equations for heavy-ion reactions based on the no-Coriolis approximation. Our method is superior to other methods in that it easily enables us to study the cases where the initial spin of the colliding particle is not zero. It can also be easily applied to the c...
متن کاملQuantum Phenomenology with the Path Integral Approach
A quantum measurement model based upon restricted path-integrals allows us to study measurements of generalized position in various one-dimensional systems of phenomenological interest. After a general overview of the method we discuss the cases of a harmonic oscillator, a bistable potential and two coupled systems, briefly illustrating their applications.

متن کاملA Path Integral Approach to the Kontsevich Quantization Formula
We give a quantum field theory interpretation of Kontsevich's deformation quantization formula for Poisson manifolds. We show that it is given by the perturbative expansion of the path integral of a simple topological bosonic open string theory. Its Batalin-Vilkovisky quantization yields a superconformal field theory. The associativity of the star product, and more generally the formality conje...
