Stochastic Analysis and Regeneration of Rough Surfaces

G. R. Jafari, S. M. Fazeli, F. Ghasemi +4

We investigate Markov property of rough surfaces. Using stochastic analysis we characterize the complexity of the surface roughness by means of a Fokker-Planck or Langevin equation…

Separability in Asymmetric Phase-Covariant Cloning

A. T. Rezakhani, S. Siadatnejad, A. H. Ghaderi

Here, asymmetric phase-covariant quantum cloning machines are defined and trade-off between qualities of their outputs and its impact on entanglement properties of the outputs are…

Characteristic Angular Scales in Cosmic Microwave Background Radiation

F. Ghasemi, A. Bahraminasab, M. Sadegh Movahed +3

We investigate the stochasticity in temperature fluctuations in the cosmic microwave background (CMB) radiation data from {\it Wilkinson Microwave Anisotropy Probe}. We show that t…

Possibility of Magnetic Mass Detection by the Next Generation of Microlensing Experiments

Sohrab Rahvar, Farhang Habibi

We study the possibility of magnetic mass detection by the gravitational microlensing technique. Recently the theoretical effect of magnetic mass in the NUT space on the microlensi…

Theory of Neutron Scattering for Gapless Neutral Spin-1 Collective Mode in Graphite

S. A. Jafari, G. Baskaran

Using tight binding band picture for 2D graphite, and the Hubbard interaction, recently we obtained a gapless, neutral spin-1 collective mode in graphite \cite{SZS}. In this paper…
