We develop a new efficient approach for the simulation of static properties of quantum systems using path integral molecular dynamics in combination with metadynamics. We use the isomorphism between a quantum system and a classical one in which a quantum particle is mapped into a ring polymer.

The matrix elements between wavelets of the quantum propagator for a large class of Hamiltonians on the half-line are given in terms of path integral. It is a sum over path defined on the upper half plane with a Wiener measure associated to the hyperbolic Laplacian in the limit where the diffusion constant diverges.

The paper presents experimental evidence for homing by path integration in a bird. Using a mammalian model case, the essentials of a cybernetical theory of this type of navigation are developed. As a consequence of its application to the extant data on geese, the necessary information about the translatory component of the animal’s movement along its ...

Optimal combination of environmental cues and path integration during navigation
Memory and Cognition, 2017 Navigation is influenced by body-based self-motion cues that are integrated over time, in a process known as path integration, as well as by environmental cues such as landmarks and room shape.
