    • Microscopic aspects of friction 

      Çıracı, Salim; Buldum, Alper (Kluwer Academic Publishers, 1997)
      In this work we first present an analysis of the interaction energy and short range forces between two parallel and atomically flat metal slabs. Using the self-consistent field pseudopotential method within the local density ...

    • Conductance in nanowires 

      Mehrez, H.; Çıracı, Salim (Kluwer Academic Publishers, 1997)
      This paper presents a detailed analysis of conductance and atomic structure in metal nanowires under tensile stress. We calculate the variation of conductance with the crossection of the constriction between two reservoirs, ...

      Hakioğlu, Tuğrul (Springer, 1997)
      The Dicke model is examined in the limit of large number of atoms and /or large number of excitations. Superfluous instabilities arising from the rotating wave approximation is examined and counterrotating terms are shown ...

    • Superconductivity in ultrasmall metallic particles 

      Boyacı, Hüseyin; Gedik, Zafer; Kulik, Igor O. (Kluwer Academic Publishers, 2000)
      Recent single electron transport experiments in nanometer size samples renewed the question about the lower limits of the size of superconductors, and the crossover from superconducting to normal state. In order to give ...
    • Theory of tip—sample interactions 

      Çıracı, Salim (Springer, 1993)
      In conventional, Scanning Tunneling Microscopy (STM) the tip—sample separation is assumed to be sufficiently large to allow only weak coupling between the electronic states. In this case the electrodes have been considered ...
    • Aharonov-Bohm effect induced by light 

      Kulik, Igor O.; Shumovsky, Alexander S. (Springer, Dordrecht, 1998)
      The quantum interferometry of normal metallic loops based on the Aharonov-Bohm effect is usually applied to measurements at low temperatures in the case of static or slowly time-varying magnetic fields (e.g., see [1]). ...
    • Quantum optics and solid state spectroscopy 

      Shumovsky, Alexander S. (Springer, 1997)
      Possibility of formation of strongly correlated states of the bosonic excitations in solids similar to the squeezed states of photons is considered. The possibility of observation of these states in optical spectroscopy ...
    • Quantum multipole radiation 

      Shumovsky, Alexander S. (John Wiley & Sons, 2001)
      The author reviews investigations of the photon localization and quantum phase problems based on the use of the representation of multipole photons. Section II presents a general consideration of the field quantization, ...
    • Defect luminescence in some layered binary chalcogenide semiconductors 

      Aydinli, A.; Gasanly, N. M. (Scientific.Net, 2002)
      A number of semiconductors such as GaS, GaSe, GaSSe show layered structure where intralayer bonding is strong and interlayer bonding quite weak. With bandgaps mostly in the visible and the near infrared and high crystal ...
    • Tunable deflection and asymmetric transmission of THz waves using a thin slab of graphene-dielectric metamaterial, with and without ENZ components 

      Serebryannikov, A. E.; Hajian, H.; Beruete, M.; Ozbay, E.; Vandenbosch, G. A. E. (Optical Society of America, 2018)
      Tunable deflection of obliquely incident, linearly polarized terahertz waves is theoretically studied in a wide frequency range around 20 THz, by combining a thin slab of graphene-dielectric metamaterial (with ten layers ...
    • Density-wave instability and collective modes in a bilayer system of antiparallel dipoles 

      Akaturk, E.; Abedinpour, S. H.; Tanatar, B. (IOP Publishing, 2018-01)
      We consider a bilayer of dipolar particles in which the polarization of dipoles is perpendicular to the planes, in the antiparallel configuration. Using accurate static structure factor S q( ) data from hypernetted-chain ...
