U(1) Gauge Field in 6D Space-Time With Compact Noncommutative Dimensions: A Coherent State Approach
M. Nasseri, A. Jahan, M. Souri
We consider the U(1) gauge field defined over a six dimensional space-time with extra dimensions compactified on a noncommutative toroidal orbifold, within the context of coherent…
Cosmological Implications of a Lorentz Invariance Violating O(2) Model
A. Jahan
We derive the free energy of a Lorentz invariance violating (LIV) O(2) model, for which a non-vanishing commutator among it's momenta is supposed. Then we investigate the possible…
Scalar-Graviton Scattering in Noncommutative Space and Deformed Newton Gravity
A. Jahan, A. Parvishi
The isotropy of Newton potential in noncommutative space disappears as it deforms to a momentum dependent one. We generalize the earlier derivation of such a deformed potential to…
Noncommutative Harmonic Oscillator at Finite Temperature: A Path Integral Approach
A. Jahan
We use the path integral approach to a two-dimensional noncommutative harmonic oscillator to derive the partition function of the system at finite temperature. It is shown that the…
Lagrangian Approach to O(2N) Model with -deformed Target Space
A. Jahan, M. Nasseri
We use the lagrangian approach to derive the free energy of a O(2N) model with -deformed target space at finite temperature.
