Unifying Theory for Casimir Forces: Bulk and Surface Formulations

Universe, 2021
The principles of the electromagnetic fluctuation-induced phenomena such as Casimir forces are well understood. However, recent experimental advances require universal and efficient methods to compute these forces.

The Feynman effective classical potential in the Schr\"odinger formulation

, 1998
New physical insight into the correspondence between path integral concepts and the Schr\"odinger formulation is gained by the analysis of the effective classical potential, that is defined within the Feynman path integral formulation of statistical ...

T T ¯ $$ T\overline{T} $$ deformations, massive gravity and non-critical strings

Journal of High Energy Physics, 2020
The T T ¯ $$ T\overline{T} $$ deformation of a 2 dimensional field theory living on a curved space- time is equivalent to coupling the undeformed field theory to 2 dimensional ‘ghost-free’ massive gravity. We derive the equivalence classically, and using

Path Integral Approach to 't Hooft's Derivation of Quantum from Classical Physics

, 2004
We present a path-integral formulation of 't Hooft's derivation of quantum from classical physics. The crucial ingredient of this formulation is Gozzi et al.'s supersymmetric path integral of classical mechanics.

State-dependent diffusion: thermodynamic consistency and its path integral formulation [PDF]

, 2007
The friction coefficient of a particle can depend on its position as it does when the particle is near a wall. We formulate the dynamics of particles with such state-dependent friction coefficients in terms of a general Langevin equation with ...

Path Integral Discussion for Smorodinsky-Winternitz Potentials: I.\ Two- and Three Dimensional Euclidean Space

, 1994
Path integral formulations for the Smorodinsky-Winternitz potentials in two- and three-dimen\-sional Euclidean space are presented. We mention all coordinate systems which separate the Smorodinsky-Winternitz potentials and state the corresponding path ...

Asymptotic boundary conditions and square integrability in the partition function of AdS gravity

Journal of High Energy Physics, 2020
There has been renewed interest in the path-integral computation of the partition function of AdS3 gravity, both in the metric and Chern-Simons formulations.

Universal Nonlinear Filtering Using Feynman Path Integrals II: The Continuous-Continuous Model with Additive Noise

, 2007
In this paper, the Feynman path integral formulation of the continuous-continuous filtering problem, a fundamental problem of applied science, is investigated for the case when the noise in the signal and measurement model is additive.

Chiral Anomalies via Classical and Quantum Functional Methods

, 2004
In the quantum path integral formulation of a field theory model an anomaly arises when the functional measure is not invariant under a symmetry transformation of the Lagrangian.
