    Notes: Summary. By means of the fixed point theorems of Schauder and Banach, we obtain an existence criterion for the nondecreasing, convex and C 2-solutions of the iterative functional-differential equation¶¶ $ x^{\prime} = H(t,x^{[n_{1}]},\dots,x^{[n_{k}]}) $ .¶Continuous dependence of solutions on parameters is also established.

    New β-delayed proton precursor 149Yb near the proton drip line (2001)

    Notes: Abstract. The β-delayed proton precursor 149Yb was synthesized in the reaction 112Sn(40Ca, 3n) and identified by using a proton-gamma coincidence measurements in combination with a helium-jet fast tape transport system. Its β-delayed proton spectrum was observed. The half-life of 149Yb was determined to be 0.7±0.2 s. The 253, 101, and 365 keV γ transitions in 147Dy, following β-delayed proton emission of 148Ho decay, were reported for the first time.

    Pairwise entanglement in symmetric multi-qubit systems (2002)
    Springer
    The European physical journal 18 (2002), S. 385-391

    Notes: Abstract: For pairs of particles extracted from a symmetric state of N two-level systems, the two-particle density matrix is expressed in terms of expectation values of collective spin operators for the large system. Results are presented for experimentally relevant examples of pure states: Dicke states | S, M〉, spin coherent, and spin squeezed states, where only the symmetric subspace, S = N/2 is populated, and for thermally entangled mixed states populating also lower S values. The entanglement of the extracted pair is then quantified by a calculation of the concurrence, which provides directly the entanglement of formation of the pair.
