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…
Competing SDW Phases and Quantum Oscillations in (TMTSF)2ClO4 in Magnetic Field
Danko Radic, Drazen Zanchi, Aleksa Bjelis
We propose a new approach for studying spin density waves (SDW) in the Bechgaard salt (TMTSF)2ClO4 where lattice is dimerized in transverse direction due to anion ordering. The SDW…
Magnetic oscillations and field induced spin density waves in (TMTSF)_2ClO_4
D. Radic, A. Bjelis, D. Zanchi
We report an analysis of the effects of magnetic field on a quasi-one-dimensional band of interacting electrons with a transverse dimerizing potential. One-particle problem in bond…
Discrete approach to incoherent excitations in conductors
P. Zupanovic, A. Bjelis, Z. Agic
Keeping the discretness of the reciprocal space we calculate the spectrum of incoherent electron-hole excitations in the conducting Fermi liquids. The metod is illustrated on the w…
Acoustic collective excitations and static dielectric response in incommensurate crystals with real order parameter
V. Dananic, A. Bjelis, M. Latkovic
Starting from the basic Landau model for the incommensurate-commensurate materials of the class II, we derive the spectrum of collective modes for all (meta)stable states from the…
