Noncommutative deformations of quantum field theories, locality, and causality
Michael A. Soloviev
We investigate noncommutative deformations of quantum field theories for different star products, particularly emphasizing the locality properties and the regularity of the deforme…
Failure of microcausality in noncommutative field theories
Michael A. Soloviev
We revisit the question of microcausality violations in quantum field theory on noncommutative spacetime, taking as a sample observable. Using methods of the th…
Noncommutativity and theta-locality
Michael A. Soloviev
In this paper, we introduce the condition of theta-locality which can be used as a substitute for microcausality in quantum field theory on noncommutative spacetime. This condition…
Axiomatic formulations of nonlocal and noncommutative field theories
Michael A. Soloviev
We analyze functional analytic aspects of axiomatic formulations of nonlocal and noncommutative quantum field theories. In particular, we completely clarify the relation between th…
PCT, spin and statistics, and analytic wave front set
Michael A. Soloviev
A new, more general derivation of the spin-statistics and PCT theorems is presented. It uses the notion of the analytic wave front set of (ultra)distributions and, in contrast to t…
