Dielectric properties of multiband electron systems: II - Collective modes
P. Zupanovic, A. Bjelis, S. Barisic
Starting from the tight-binding dielectric matrix in the random phase approximation we examine the collective modes and electron-hole excitations in a two-band electronic system. F…
Phase Diagram for Charge Density Waves in a Magnetic Field
D. Zanchi, A. Bjeliš, G. Montambaux
The influence of an external magnetic field on a quasi one-dimensional system with a charge density wave (CDW) instability is treated within the random phase approximation which in…
THE TIGHT-BINDING APPROACH TO THE DIELECTRIC RESPONSE IN THE MULTIBAND SYSTEMS
P. Zupanovic, A. Bjelis, S. Barisic
Starting from the random phase approximation for the weakly coupled multiband tightly-bounded electron systems, we calculate the dielectric matrix in terms of intraband and interba…
Domain Patterns in Incommensurate Systems with the Uniaxial Real Order Parameter
V. Dananic, A. Bjelis, Zagreb +1
The basic Landau model for the incommensurate-commensurate transition to the uniform or dimerized uniaxial ordering is critically reexamined. The previous analyses identified only…
