Appearance of new lines and change in line shape in the IR spectrum of a NaV_2O_5 single crystal at the spin-Peierls transition
M. N. Popova, A. B. Sushkov, A. N. Vasil'ev +2
We report the first observation of new lines in the infrared spectrum of a crystal due to unit-cell doubling at the spin-Peierls transition (in NaV_2O_5). The change in the shape o…
Raman, infrared and optical spectra of the spin-Peierls compound NaV_2O_5
S. A. Golubchik, M. Isobe, A. N. Ivlev +5
We have measured polarized spectra of Raman scattering, infrared and optical transmission of NaV_2O_5 single crystals above the temperature of the spin-Peierls transition Tsp=35 K.…
Folded modes in the infrared spectra of the spin-Peierls phase of CuGeO_3
M. N. Popova, A. B. Sushkov, S. A. Golubchik +2
Polarized far-infrared transmittance spectra of CuGeO_3 single crystals were measured at different temperatures (6K < T < 300K). Two spectral lines, at 284.2 cm-1 in E||c polarizat…
q-Functional Field Theory for particles with exotic statistics
K. N. Ilinski, G. V. Kalinin, A. S. Stepanenko
In the paper we give consecutive description of functional methods of quantum field theory for systems of interacting q-particles. These particles obey exotic statistics and appear…
q-Functional Wick's theorems for particles with exotic statistics
K. N. Ilinski, G. V. Kalinin, A. S. Stepanenko
In the paper we begin a description of functional methods of quantum field theory for systems of interacting q-particles. These particles obey exotic statistics and are the q-gener…
Spin-density and charge-density excitations in quantum wires
Arne Brataas, A. G. Mal'hukov, Christoph Steinebach +2
We study an interacting electron gas in a quantum wire within the Hartree-Fock random phase approximation. Vertex corrections to the electron spin polarizability due to the electro…
