Topological instability of two-dimensional conductors
Anatoly M. Kadigrobov, Aleksa Bjeliš, Danko Radić
In the present paper we propose a mechanism of the structural instability with a periodic charge ordering in two-dimensional isotropic conductors with a closed Fermi surface which…
New SDW phases in quasi-one-dimensional systems dimerized in the transverse direction
D. Zanchi, A. Bjelis
The spin density wave instabilities in the quasi-one-dimensional metal (TMTSF)_2ClO_4 are studied in the framework a matrix random phase approximation for intra-band and inter-band…
Collective modes in uniaxial incommensurate-commensurate systems with the real order parameter
V. Dananic, A. Bjelis, M. Latkovic
The basic Landau model for uniaxial systems of the II class is nonintegrable, and allows for various stable and metastable periodic configurations, beside that representing the uni…
Landau Model for Commensurate-Commensurate Phase Transitions in Uniaxial Improper Ferroelectric Crystals
M. Latkovic, A. Bjelis, V. Dananic
We propose the Landau model for lock-in phase transitions in uniaxially modulated improper ferroelectric incommensurate-commensurate systems of class I. It includes Umklapp terms o…
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…
