Photo-emission properties of quasi-one-dimensional conductors
Z. Agic, P. Zupanovic, A. Bjelis
We calculate the self-energy of one-dimensional electron band with the three-dimensional long range Coulomb interaction within the random phase approximation, paying particular att…
Crystal stability and optical properties of organic chain compounds
P. Zupanovic, A. Bjelis, S. Barisic
The solution to the long standing problem of the cohesion of organic chain compounds is proposed. We consider the tight-binding dielectric matrix with two electronic bands per chai…
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…
Dielectric properties of multiband electron systems: I - Tight-binding formulation
P. Zupanovic, A. Bjelis, S. Barisic
The screened electron-electron interaction in a multi-band electron system is calculated within the random phase approximation and in the tight-binding representation. The obtained…
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…
