SPIN-STATISTICS THEOREM IN PATH INTEGRAL FORMULATION [PDF]
International Journal of Modern Physics A, 2001 We present a coherent proof of the spin-statistics theorem in path integral formulation. The local path integral measure and Lorentz-invariant local Lagrangian, when combined with the Green functions defined in terms of time ordered products, ensure causality regardless of statistics. The Feynman m-iε prescription ensures the positive energy condition

Path-integral formulation of closed strings [PDF]
Physical Review D, 1987 We construct the covariant path integral for the Neveu-Schwarz-Ramond superstring in superspace, with manifest invariance under diffeomorphisms and local supersymmetry transformations. Spin structure is introduced, and the constraints imposed by modular invariance on fermionic string models examined.

Pauli-Villars’ regularization of ghosts in path-integral string formulation
Journal of High Energy Physics, 2023 I consider Pauli-Villars’ regulators for the ghosts in the path-integral string formulation and show how they preserve conformal invariance. I calculate the regulator contributions to the effective action and to the central charge and demonstrate the ...

Path integral implementation of relational quantum mechanics
Scientific Reports, 2021 Relational formulation of quantum mechanics is based on the idea that relational properties among quantum systems, instead of the independent properties of a quantum system, are the most fundamental elements to construct quantum mechanics.

T T ¯ $$ T\overline{T} $$ + Λ2 from a 2d gravity path integral
Journal of High Energy Physics, 2023 We develop a two-dimensional gravity path integral formulation of the T T ¯ $$ T\overline{T} $$ + Λ2 deformation of quantum field theory. This provides an exactly solvable generalization of the pure T T ¯ $$ T\overline{T} $$ deformation that is relevant ...

Bosonization in the path integral formulation [PDF]
Physical Review D, 2015 We establish the direct $d=2$ on-shell bosonization $ _{L}(x_{+})=e^{i (x_{+})}$ and $ _{R}^{\dagger}(x_{-})=e^{i (x_{-})}$ in path integral formulation by deriving the off-shell relations $ _{L}(x) _{R}^{\dagger}(x)=\exp[i (x)]$ and $ _{R}(x) _{L}^{\dagger}(x)=\exp[-i (x)]$.

A new three-dimensional J-integral formulation for arbitrary load history and finite deformation
Nihon Kikai Gakkai ronbunshu, 2018 In this paper, a new formulation of three-dimensional J-integral for the evaluation of elastic-plastic fracture problem is presented. It is known that the J-integral represents the energy release rate per unit crack extension.

Fully Symmetric Relativistic Quantum Mechanics and Its Physical Implications
Mathematics, 2021 A new formulation of relativistic quantum mechanics is presented and applied to a free, massive, and spin-zero elementary particle in the Minkowski spacetime. The reformulation requires that time and space, as well as the timelike and spacelike intervals,
