Integrable KdV Systems: Recursion Operators of Degree Four
Metin Gurses, Atalay Karasu
The recursion operator and bi-Hamiltonian formulation of the Drinfeld- Sokolov system are given
Suppression of superconductivity in high- cuprates due to nonmagnetic impurities: Implications for the order parameter symmetry
M. Bayindir, Z. Gedik
We studied the effects of nonmagnetic impurities on high-temperature superconductors by solving the Bogoliubov-de Gennes equations on a two-dimensional lattice via exact diagonaliz…
Disorder and Localization in the Lowest Landau Level
Z. Gedik, M. Bayindir
We study the localization property of a two-dimensional noninteracting electron gas in the presence of randomly distributed short-range scatterers. We evaluate the participation nu…
Bose-Einstein condensation in a one-dimensional interacting system due to power-law trapping potentials
M. Bayindir, B. Tanatar, Z. Gedik
We examine the possibility of Bose-Einstein condensation in one-dimensional interacting Bose gas subjected to confining potentials of the form , in whi…
Finite-dimensional Schwinger basis, deformed symmetries, Wigner function, and an algebraic approach to quantum phase
T. Hakioglu
Schwinger's finite (D) dimensional periodic Hilbert space representations are studied on the toroidal lattice ${\ee Z}_{D} \times {\ee Z}_{D}$ with specific emphasis on the deforme…
Dynamical properties of the two-dimensional Holstein-Hubbard model in the normal state at zero temperature: A fluctuation-based effective cumulant approach
T. Hakioglu, M. Ye. Zhuravlev
The two-dimensional many-body Holstein-Hubbard model in the T=0 normal state is examined within the framework of the self-consistent coupling of charge fluctuation correlations to…
