Path Integral Approach to Noncommutative Spacetimes
We propose a path integral formulation of noncommutative generalizations of spacetime manifold in even dimensions, characterized by a length scale λP . The commutative case is obtained in the limit λP = 0. PACS numbers: 04.60.Gw, 04.60.-m, 02.40-k. ∗E-mail: [email protected]
متن کاملNoncommutative Harmonic Oscillator at Finite Temperature: A Path Integral Approach
Recently, there has been an immense amount of challenge devoted to the subject of noncommutative space-time. Although, the idea of noncommutating space-time coordinates is an old proposal [1], the recent discoveries in string/M theories were the main source of renewed interests in the subject [2]. In particular, much work is dedicated to study the noncommutative version of the quantum field the...
متن کاملPath Integral Formulation of Noncommutative Quantum Mechanics
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. Noncommutative quantum mechanics represents a natural extension of usual quantum mechanics, in which one allows nonvanishing commutators ...
متن کاملPath Integral Quantisation of Finite Noncommutative Geometries
We present a path integral formalism for quantising the spectral action of noncommutative geometry, based on the principle of summing over all Dirac operators. The approach is demonstrated on two simple finite noncommutative geometries. On the first, the graviton is described by a Higgs field, and on the second, it is described by a gauge field. We start with the partition function, and calcula...
متن کاملTopological anomalies from the path integral measure in superspace
A fully quantum version of the Witten-Olive analysis of the central charge in the N = 1 Wess-Zumino model in d = 2 with a kink solution is presented by using path integrals in superspace. We regulate the Jacobians with heat kernels in superspace, and obtain all superconformal anomalies as one Jacobian factor. The conserved quantum currents differ from the Noether currents by terms proportional ...
