Quantitatively correct UVvis spectrum of ferrocene with TDB3LYP
(American Chemical Society, 2013)The ultravioletvisible light (UVvis) absorption spectrum of ferrocene is modeled with timedependent density functional theory employing LSDA, BLYP, B3LYP, and CAMB3LYP functionals in combination with 631G*, 631+G*, ...

Quantization errors in overlapped block digital filtering methods
(IARIA, 2013)In digital signal processing applications involving filtering long sequences, block filtering methods like overlapsave and overlapadd are widely used. Like all finiteprecision applications, overlapsave and overlapadd ... 
Quantum and classical integrable sineGordon model with defect
(Elsevier BV * NorthHolland, 2008)Defects which are predominant in a realistic model, usually spoil its integrability or solvability. We on the other hand show the exact integrability of a known sineGordon field model with a defect (DSG), at the classical ... 
Quantum bistability, structural transformation, and spontaneous persistent currents in mesoscopic aharonovbohm loops
(World Scientific Publishing Co., 2005)Fixednumberofelectron mesoscopic or macromolecular conducting ring is shown to support persistent currents due to AharonovBohm flux, and the "spontaneous" persistent currents without the flux when structural transformation ... 
Quantum canonical transformations in starproduct formalism
(IOP, 2013)We study construction of the starproduct version of three basic quantum canonical transformations which are known as the generators of the full canonical algebra. By considering the fact that starproduct of cnumber ... 
Quantum canonical transformations in WeylWignerGroenewoldMoyal formalism
(2009)A conjecture in quantum mechanics states that any quantum canonical transformation can decompose into a sequence of three basic canonical transformations; gauge, point and interchange of coordinates and momenta. It is shown ... 
Quantum computation with persistentcurrent AharonovBohm qubits and qugates
(Computational Publications, 2003)We analyse the possibility of employing mesoscopic or nanoscopic rings of a normal metal in a double degenerate persistentcurrent state in the presence of the AharonovBohm flux equal to the half flux quantum as entangled ... 
Quantum computational gates with radiation free couplings
(Springer, 2002)Abstract.We examine a generic three level mechanism of quantum computation in which all fundamentalsingle and double qubit quantum logic gates are operating under the effect of adiabatically controllablestatic (radiation ... 
Quantum correlated light pulses from sequential superradiance of a condensate
(2009)We discover an inherent mechanism for entanglement swap associated with sequential superradiance from an atomic BoseEinstein condensate. Based on careful examinations with both analytical and numerical approaches, we ... 
Quantum correlations among superradiant boseeinstein condensate atoms
(M A I K Nauka  Interperiodica, 2010)Quantum correlations among atoms in superradiant BoseEinstein condensates are discussed. It is shown that atoms in the superradiant atomic condensate can exhibit continuous variable quantum entanglement analogous to ... 
Quantum correlations of spin1 atoms in an optical lattice
(Institute of Physics Publishing, 2009)In this work, we investigate the system of cold spin1 atoms in a one dimensional optical lattice in relation with squeezing and entanglement. By using the corresponding BoseHubbard Hamiltonian, both superfluid and ... 
Quantum dot functionalized Titania systems for photocatalytic oxidative NOx storage
