Charged bosons in a quasionedimensional system
Tanatar, Bilal; Davoudi, B.; Kohandel, M. (American Physical Society, 2000)The groundstate properties of a system of charged bosons in a quasionedimensional model with a neutralizing background are investigated within the hypernettedchain approximation. Strong correlation effects drive the ... 
Comparative study of screened interlayer interactions in the Coulomb drag effect in bilayer electron systems
Asgari, R.; Tanatar, Bilal; Davoudi, B. (The American Physical Society, 2008)Coulomb drag experiments in which the interlayer resistivity is measured are important as they provide information on the Coulomb interactions in bilayer systems. When the layer densities are low correlation effects become ... 
Dynamic correlations in doublelayer electron systems
Tanatar, Bilal; Davoudi, B. (The American Physical Society, 2001)We study the effects of dynamic correlations on the groundstate properties of a doublelayer twodimensional electron gas within the quantum SingwiTosiLandSjölander theory (STLS). The intralayer and interlayer static ... 
Dynamical correlations in Coulomb drag effect
Tanatar, Bilal; Davoudi, B.; Hu, B.Y.K. (Elsevier, 2003)Motivated by recent Coulomb drag experiments in pairs of lowdensity twodimensional (2D) electron gases, we investigate the influence of correlation effects on the interlayer drag rate as a function of temperature. We use ... 
Effective mass enhancement in twodimensional electron systems: The role of interaction and disorder effects
Asgari, R.; Davoudi, B.; Tanatar, Bilal (Elsevier, 2004)Recent experiments on twodimensional (2D) electron systems have found a sharp increase in the effective mass of electrons with decreasing electron density. In an effort to understand this behavior we employ the manybody ... 
Freezing transition of the vortex liquid in a layered superconductor
Davoudi, B.; Kohandel, M.; Tanatar, Bilal (Elsevier Science Publishers B.V., 2001)The selfconsistent theory of Singwi, Tosi, Land, and Sjolander is used to describe the liquidsolid phase in a layered superconductor in the limit of weak interplane correlation effects as would be applicable to BSCCO ... 
Groundstate properties of the twodimensional charged Bose gas
Davoudi, B.; Strepparola, E.; Tanatar, Bilal; Tosi, M. P. (American Physical Society, 20010301)We study the twodimensional gas of charged bosons interacting via a logarithmic potential within the quantal hypernettedchain approximation. The pair correlation function, the static structure factor, the groundstate ... 
Hardcore Yukawa model for chargestabilized colloids
Davoudi, B.; Kohandel, M.; Mohammadi, M.; Tanatar, Bilal (American Physical Society, 2000)The hypernetted chain approximation is used to study the phase diagram of a simple hardcore Yukawa model of a chargestabilized colloids. We calculate the static structure factor, the pair distribution function, and the ... 
Hardcore Yukawa model for twodimensional chargestabilized colloids
Asgari, R.; Davoudi, B.; Tanatar, Bilal (American Physical Society, 200110)The hypernetted chain and PercusYevick approximations are used to study the phase diagram of a simple hardcore Yukawa model of chargestabilized colloidal particles in a twodimensional system. We calculate the static ... 
Plasmon dispersion and damping in doublelayer electron systems
Davoudi, B.; Tanatar, Bilal (Elsevier Science Ltd, Exeter, United Kingdom, 2000)We use dynamical localfield corrections to study the plasmon dispersion and damping in doublelayer electron systems. The wave vector and frequencydependent localfields describing the exchangecorrelation effects are ...
