Multipole radiation in quantum domain
(Springer, 2003)We review recent results based on the application of spherical wave representation to description of quantum properties of multipole radiation generated by atomic transitions. In particular, the angular momentum Angular ... 
Physics and applications of defect structures in photonic crystals
(Springer, 2003)We propose and demonstrate a new type of propagation mechanism for electromagnetic waves in photonic band gap materials. Photons propagate through coupled cavities due to interaction between the highly localized neighboring ... 
Different scattering regimes in twodimensional BoseEinstein condensates
(Springer, 2003)Motivated by the recent efforts to produce lowdimensional condensates, we study the groundstate density profiles of twodimensional BoseEinstein condensed atoms at zero temperature within a meanfield theory. The interplay ...

10 W, 10 ns, 50 kHz allfiber laser at 1.55 µm
(Optical Society of America, 2012)We report on an allfiber, singlemode MOPA system at 1.55 µm producing 10ns, 200µJ pulses with 20 kW of peak power and utilize it to micromachine crystalline Si, which is largely transparent at this wavelength. 
Burstmode Yb fiber amplifier producing 40 µJ individual pulse energyBurstmode Yb fiber amplifier producing 40 µJ individual pulse energy
(Optical Society of America, 2012)We report 40µJ individual pulse energy for 100ns long amplified bursts with homogenized energy distribution from a 1kHz Ybfiber amplifier. Initial results on micromachining using burstmode femtosecond pulses are ... 
Macroscopic assembly of indefinitely long and parallel nanowires into large area photodetection circuitry
(Optical Society of America, 2012)We demonstrate a novel fabrication technique of a photodetection circuitry with light sensitive pixels consisting of hundreds of long and parallel selenium nanowires. Using 10x10 pixel format, alphabetic characters were ... 
Predictions of singlelayer honeycomb structures from first principles
(Cambridge University Press, 2017) 
Persistent current in a mesoscopic ring with strongly coupled polarons
(Springer, 2000)We investigate influence of the electronphonon interaction on persistent current in a mesoscopic ring threaded by a AharonovBohm 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 timeindependent (or magnetic) ... 
Optical spectroscopy of microcavities
(Springer, 1997)Microcavities, such as microspheres, possess morphologydependent 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 ... 
Nondecaying currents in normal metals
(Springer, 2000)In a present paper, we review cases when stable, timeindependent currents may flow in normal metals, both singleconnected or multipleconnected, in presence of magnetic field or the field of vector potential. These include ... 
Negative refraction and subwavelength focusing in twodimensional photonic crystals
(SpringerVerlag, 2007)We experimentally and theoretically demonstrate negative refraction and focusing on electromagnetic (EM) waves by using twodimensional 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 selfconsistent field pseudopotential method within the local density ...

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, ...
