Computational modeling of quantum-confined impact ionization in Si nanocrystals embedded in SiO2
(2007)Injected carriers from the contacts to delocalized bulk states of the oxide matrix via Fowler-Nordheim tunneling can give rise to quantum-confined impact ionization (QCII) of the nanocrystal (NC) valence electrons. This ... -
A Hamiltonian-based solution to the mixed sensitivity optimization problem for stable pseudorational plants
(Elsevier, 2005-11)This paper considers the mixed sensitivity optimization problem for a class of infinite-dimensional stable plants. This problem is reducible to a two- or one-block H∞ control problem with structured weighting functions. ... -
A model-based scheme for anticontrol of some chaotic systems
(World Scientific Publishing, 2003)We consider a model-based 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 model-based scheme for anticontrol of some discrete-time chaotic systems
(World Scientific, 2004)We consider a model-based approach for the anticontrol of some discrete-time 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 ... -
Non-local, non-commutative 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 h-independent 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
(2004)It is shown that the system of an even number of three-level 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 Bose-Einstein condensate in a rotating anisotropic trap
(American Physical Society, 2004)The behavior of Bose-Einstein condensates (BEC) with a vortex lattice in a rotating anisotropic trap was studied. The single-particle wave functions for a rotating anisotropy trap were found by exactly diagonalizing the ...
