  • Predictions of single-layer honeycomb structures from first principles 

    Çıracı, Salim; Cahangirov, Seymur (Cambridge University Press, 2017)
  • Persistent current in a mesoscopic ring with strongly coupled polarons 

    Bayındır, Mehmet; Kulik, Igor O. (Springer, 2000)
    We investigate influence of the electron-phonon interaction on persistent current in a mesoscopic ring threaded by a Aharonov-Bohm flux Φ. We find that all thermodynamic quantities are still periodic in Φ with a period Φo ...
  • Persistent current and persistent charge in nanostructures 

    Kulik, Igor O. (Springer, 1997)
    Quantúm effects in the interaction of electromagnetic field with small, but not microscopically small, metallic particles and rings are investigated. The aspects of mesoscopic systems related to time-independent (or magnetic) ...
  • Optical spectroscopy of microcavities 

    Serpengüzel, Ali; Arnold, S.; Lock, J. A.; Griffel, G. (Springer, 1997)
    Microcavities, such as microspheres, possess morphology-dependent resonances (MDR’s). In this chapter light coupling mechanisms to MDR’s is examined. The novel mechanism of excitation of the microsphere with an optical ...
  • Nonlinear phenomena in metallic contacts 

    Kulik, Igor O. (Springer, 2000)
    We review and extend theoretical approaches to nonlinear and nonequilibrium effects in metallic microcontacts ranging in their dimension from the atomic to macroscopic sizes. Atomic contacts are shown to quantize their ...
  • Non-decaying currents in normal metals 

    Kulik, Igor O. (Springer, 2000)
    In a present paper, we review cases when stable, time-independent currents may flow in normal metals, both single-connected or multiple-connected, in presence of magnetic field or the field of vector potential. These include ...
  • Negative refraction and subwavelength focusing in two-dimensional photonic crystals 

    Özbay, Ekmel; Özkan, Gonca (Springer-Verlag, 2007)
    We experimentally and theoretically demonstrate negative refraction and focusing on electromagnetic (EM) waves by using two-dimensional photonic crystal slabs at microwave frequencies. Negative refraction is observed both ...
  • 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 ...
  • Locality of quantum electromagnetic radiation 

    Shumovsky, Alexander S. (Apeiron, 2002)
  • Preface 

    Abstreiter, G.; Aydınlı, Atilla; Leburton, J. -P. (Kluwer Academic Publishers, 1997)
  • 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, ...
  • Band-gap renormalization in quasi-one-dimensional systems 

    Tanatar, Bilal (Kluwer Academic Publishers, 1997)
  • Interaction of two-level atomic system with a single-mode radiation field 

    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 ...
  • First-Principles atomic-scale study of superlow friction 

    Çıracı, Salim; Dağ, S.; Gülseren, O.; Yıldırım, T. (Springer, Berlin, Heidelberg, 2007)
  • 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 ...
