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

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.

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 ...

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.

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.

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 formulation of conformal anomalies

Zeitschrift f�r Physik C Particles and Fields, 1986
We present a path-integral formulation of conformal anomalies and point out an intimate interplay of the local Poincare anomaly and the dilatational anomaly. A key observation in our approach is that the algorithm of the path-integral formulation has natural foundation within the zeta-function regularization scheme.

A New Space-Time Theory Unravels the Origins of Classical Mechanics for the Dirac Equation

Quantum Reports
The Feynman path integral plays a central role in quantum mechanics, linking classical action to propagators and relating quantum electrodynamics (QED) to Feynman diagrams.

On the Relation between Operator Constraint --, Master Constraint --, Reduced Phase Space --, and Path Integral Quantisation

, 2009
Path integral formulations for gauge theories must start from the canonical formulation in order to obtain the correct measure. A possible avenue to derive it is to start from the reduced phase space formulation.
