Non-relativistic Bremsstrahlung in QED: Hamiltonian vs. Path Integral Approach
A. Jahan
An alternative derivation of the radiation intensity in non-relativistic bremsstrahlung is provided utilizing the path integral formalism. By integrating out the gauge field, one o…
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…
Gravitational Radiation in Noncommutative Gravity
A. Jahan, N. Sadeghnezhad
The gravitational radiation power of a binary system in a noncommutative space is derived and it's rate of the period decrease is calculated to first order in noncommutativity para…
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…
