QFT with twisted Poincaré invariance and the Moyal product [PDF]
Journal of High Energy Physics, 2007 We study the consequences of twisting the Poincare invariance in a quantum field theory. First, we construct a Fock space compatible with the twisting and the corresponding creation and annihilation operators. Then, we show that a covariant field linear in creation and annihilation operators does not exist. Relaxing the linearity condition, a covariant

Stochastic Moyal product on the Wiener space
Journal of Mathematical Physics, 2007We propose a stochastic extension of deformation quantization on a Hilbert space. The Moyal product is defined in this context on the space of functionals belonging to all of the Sobolev spaces of the Malliavin calculus.

The Action Functional for Moyal Planes
Letters in Mathematical Physics, 2003 latex, 10 pagesModulo some natural generalizations to noncompact spaces, we show in this letter that Moyal planes are nonunital spectral triples in the sense of Connes. The action functional of these triples is computed, and we obtain the expected result,

Twisted convolution and Moyal star product of generalized functions [PDF]
Theoretical and Mathematical Physics(Russian Federation), 2012 We consider nuclear function spaces on which the Weyl-Heisenberg group acts continuously and study the basic properties of the twisted convolution product of the functions with the dual space elements. The final theorem characterizes the corresponding algebra of convolution multipliers and shows that it contains all sufficiently rapidly decreasing ...

Computing in string field theory using the Moyal star product [PDF]
Physical Review D, 2002 Using the Moyal star product, we define open bosonic string field theory carefully, with a cutoff, for any number of string oscillators and any oscillator frequencies. Through detailed computations, such as Neumann coefficients for all string vertices, we show that the Moyal star product is all that is needed to give a precise definition of string ...

Gauging Higher-Spin-Like Symmetries Using the Moyal Product
2022Well established approaches to gauging U(1) transformations or spacetime translations lead to theories of interacting bosons of spin 1 or spin 2. We describe a novel approach to gauging their higher derivative generalizations (i.e. higher-spin-like symmetries), leading to a Yang-Mills like theory defined over a symplectic manifold dubbed “master space”.
