Experimental investigation of role of steam in entrained flow coal gasification
(Fuel, 2007)
Experimental investigations of the influence of excess oxygen coefficient, H2O/coal mass ratio using high-temperature steam, mean mass diameter of pulverized coal and coal size fraction on basic characteristics of coal ...
Investigation of the cigar burner combustion system for baled biomass
(Biomass and Bioenergy, 2013)
Biomass is deemed to be the main source of renewable energy in Serbia. Over the past couple of years, considerable efforts have been made to develop a technology which would enable biomass bales of various sizes and shapes ...
Discrete solitons in an array of quantum dots
(Physical Review B: Condensed Matter and Materials Physics, 2013)
We develop a theory for the interaction of classical light fields within a chain of coupled quantum dots (QDs), in the strong-coupling regime, taking into account the local-field effects. The QD chain is modeled by a ...
Exploring negative refraction conditions for quantum cascade semiconductor metamaterials in the terahertz spectral range
(IOP Publishing Ltd, 2016)
In order to avoid losses in metamaterial unit cells at frequencies of interest, caused by metallic inclusions, an active medium design has been proposed. As candidate structures for this active medium, we have chosen quantum ...
Sticky Goos-Hanchen effect at normal/superconductor interface
(Europhysics Letters / EPL, 2013)
We study the quantum Goos-Hanchen (GH) effect for wave-packet dynamics at a normal/superconductor (NS) interface. We find that the effect is amplified by a factor (E-F/Delta), with E-F the Fermi energy and Delta the gap. ...
High- and low-frequency phonon modes in dipolar quantum gases trapped in deep lattices
(Physical Review A, 2013)
We study normal modes propagating on top of the stable uniform background in arrays of dipolar Bose-Einstein condensate (BEC) droplets trapped in a deep optical lattice. Both the on-site mean-field dynamics of the droplets ...
Interface solitons in locally linked two-dimensional lattices
(Physical Review E, 2011)
Existence, stability, and dynamics of soliton complexes, centered at the site of a single transverse link connecting two parallel two-dimensional (2D) lattices, are investigated. The system with the onsite cubic self-focusing ...
Make slow fast -How to speed up interacting disordered matter
(Europhysics Letters / EPL, 2013)
Anderson and dynamical localization have been experimentally observed with ultra-cold atomic matter. Feshbach resonances are used to efficiently control the strength of interactions between atoms. This allows to study the ...
Interactions destroy dynamical localization with strong and weak chaos
(Europhysics Letters / EPL, 2011)
Bose-Einstein condensates loaded into kicked optical lattices can be treated as quantum kicked-rotor systems. Noninteracting rotors show dynamical localization in momentum space. The experimentally tunable condensate ...
Gap solitons in defocusing lithium niobate binary waveguide arrays fabricated by proton implantation and selective light illumination
(Applied Physics. B: Lasers and Optics, 2009)
Photovoltaic photorefractive binary waveguide arrays are fabricated by proton implantation and selective light illumination on top of an iron-doped near stoichiometric lithium niobate crystal. Linear discrete diffraction ...
