The Efficiency of Using Accretion Power of Kerr Black Holes
Ioana Dutan, Peter Biermann
The efficiency of a rapidly spinning Kerr black hole to turn accretion power into observable power can attain 32 percent for the photon emission from the disk, as is well known, fo…
Doi-Hopf modules and Yetter-Drinfeld modules for quasi-Hopf algebras
D. Bulacu, S. Caenepeel, B. Torrecillas
For a quasi-Hopf algebra , a left -comodule algebra $\mf{B}$ and a right -module coalgebra we will characterize the category of Doi-Hopf modules ${}^C{\cal M}(H)_{\mf{…
Non-zero contact and Sasakian reduction
Oana Drăgulete, Liviu Ornea
We complete the reduction of Sasakian manifolds with the non-zero case by showing that Willett's contact reduced space is compatible with the Sasakian structure. We then prove the…
Discrete quasiperiodic sets with predefined local structure
Nicolae Cotfas
Model sets play a fundamental role in structure analysis of quasicrystals. The diffraction diagram of a quasicrystal admits as symmetry group a finite group G, and there is a G-clu…
Resonant transport throught semiconductor nanostructures
E. R. Racec, P. N. Racec, U. Wulf
Transport through semiconductor nanostructures is a quantum-coherent process. This paper focuses on systems in which the electron's dynamics is ballistic and the transport is domin…
Toward a New Phenomenon: Super-Cerenkov Radiation
D. B. Ion, M. L. Ion
In this letter a new coherent gamma emission mechanism, called Super-Cerenkov radiation, is introduced. The SCR is expected to take place when the charged particle is moving in a m…
