Computational modeling of quantumconfined impact ionization in Si nanocrystals embedded in SiO2
(2007)Injected carriers from the contacts to delocalized bulk states of the oxide matrix via FowlerNordheim tunneling can give rise to quantumconfined impact ionization (QCII) of the nanocrystal (NC) valence electrons. This ... 
A Hamiltonianbased solution to the mixed sensitivity optimization problem for stable pseudorational plants
(Elsevier, 200511)This paper considers the mixed sensitivity optimization problem for a class of infinitedimensional stable plants. This problem is reducible to a two or oneblock H∞ control problem with structured weighting functions. ... 
A modelbased scheme for anticontrol of some chaotic systems
(World Scientific Publishing, 2003)We consider a modelbased approach for the anticontrol of some continuous time systems. We assume the existence of a chaotic model in an appropriate form. By using a suitable input, we match the dynamics of the controlled ... 
A modelbased scheme for anticontrol of some discretetime chaotic systems
(World Scientific, 2004)We consider a modelbased approach for the anticontrol of some discretetime systems. We first assume the existence of a chaotic model in an appropriate form. Then by using an appropriate control input we try to match the ... 
Nonlocal, noncommutative picture in quantum mechanics and distinguished continuous canonical maps
(IOP Science, 2002)It is shown that continuous classical nonlinear canonical (Poisson) maps have a distinguished role in quantum mechanics. They act unitarily on the quantum phase space and generate hindependent quantum nonlinear canonical ... 
Nonthermal Quantum Channels as a Thermodynamical Resource
(American Physical Society, 2015)Quantum thermodynamics can be understood as a resource theory, whereby thermal states are free and the only allowed operations are unitary transformations commuting with the total Hamiltonian of the system. Previous ... 
Parity effect in mesoscopic and nanoscopic superconducting particles
(Elsevier B.V., 2001)Superconductivity in small metallic specimens is studied with regard to the size dependence of the parity gap (ΔP), a parameter distinguishing between the energy of even and odd number of electrons in the granule. ΔP is ... 
Persistent perfect entanglement in atomic systems
(IOP, 2004)It is shown that the system of an even number of threelevel atoms in the Λ configuration in a cavity can evolve into a persistent maximum entangled state. The time of formation of such an entangled state is estimated. 
Spontaneous and persistent currents in superconductive and mesoscopic structures
(American Institute of Physics, 2004)We briefly review aspects of superconductive persistent currents in Josephson junctions of the S/I/S, S/O/S and S/N/S types, focusing on the origin of jumps in the current versus phase dependences, and discuss in more ... 
Vortex lattice of a BoseEinstein condensate in a rotating anisotropic trap
(American Physical Society, 2004)The behavior of BoseEinstein condensates (BEC) with a vortex lattice in a rotating anisotropic trap was studied. The singleparticle wave functions for a rotating anisotropy trap were found by exactly diagonalizing the ...
