Mixing of Frenkel and charge-transfer excitons in quasi-one-dimensional one-component molecular crystals (2009)

Lalov, I. J., Zhelyazkov, I.

In molecular crystals like MePTCDI and PTCDA the molecule are regularly arranged creating quasi-one-dimensional molecular stacks. The intermolecular distance in a stack (about 3.3 A) is comparable...

MHD waves and instabilities in flowing solar structures in the framework of Hall magnetohydrodynamics (2009)

Zhelyazkov, I.

It is well established now that the solar atmosphere, from photosphere to the corona and the solar wind is a highly structured medium. Satellite observations have confirmed the presence of steady...

Hall-MHD Surface Waves in Flowing Solar-Wind Plasma Slab (2004)

Miteva, R., Zhelyazkov, I.

We study the influence of a steady flow velocity on the dispersion characteristics of Hall- magnetohydrodynamic forward and backward sausage and kink surface waves travelling along a solar-wind...

Fast surface waves in an ideal Hall magnetohydrodynamic plasma slab (1996)

Zhelyazkov, I, Debosscher, Arnold; U0002843, Goossens, M

The propagation of fast sausage and kink magnetohydrodynamic (MHD) surface waves in an ideal magnetized plasma slab is studied taking into account the Hall term in the generalized Ohm's law. It is...
