Predictions of single-layer honeycomb structures from first principles

Persistent current in a mesoscopic ring with strongly coupled polarons
(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
(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
(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
(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
(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
(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
(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

Preface

Conductance in nanowires
(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
(Kluwer Academic Publishers, 1997) -
Interaction of two-level atomic system with a single-mode radiation field
(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
(Springer, Berlin, Heidelberg, 2007) -
Superconductivity in ultrasmall metallic particles
(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
(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
(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
(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
(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
(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 ...
