Path integration in relativistic quantum mechanics [PDF]
, 1992 The simple physics of a free particle reveals important features of the path-integral formulation of relativistic quantum theories. The exact quantum-mechanical propagator is calculated here for a particle described by the simple relativistic action ...

Path integral formulation of noncommutative quantum mechanics [PDF]
Journal of High Energy Physics, 2001 We propose a phase-space path integral formulation of noncommutative quantum mechanics, and prove its equivalence to the operatorial formulation. As an illustration, the partition function of a noncommutative two-dimensional harmonic oscillator is calculated.

(1,0) gauge theories on the six-sphere
SciPost Physics, 2019 We construct gauge theories with a vector-multiplet and hypermultiplets of $(1,0)$ supersymmetry on the six-sphere. The gauge coupling on the sphere depends on the polar angle.

Path integral representation of the evolution operator for the Dirac equation [PDF]
, 2006 A path integral representation of the evolution operator for the four-dimensional Dirac equation is proposed. A quadratic form of the canonical momenta regularizes the original representation of the path integral in the electron phase space.

A path integral formulation for particle detectors: the Unruh-DeWitt model as a line defect
Journal of High Energy Physics, 2021 Particle detectors are an ubiquitous tool for probing quantum fields in the context of relativistic quantum information (RQI). We formulate the Unruh-DeWitt (UDW) particle detector model in terms of the path integral formalism. The formulation is able to

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 ...

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.

't Hooft's quantum determinism -- path integral viewpoint [PDF]
, 2005 We present a path integral formulation of 't Hooft's derivation of quantum from classical physics. Our approach is based on two concepts: Faddeev-Jackiw's treatment of constrained systems and Gozzi's path integral formulation of classical mechanics. This
