On the convergence rates of Gauss and Clenshaw-Curtis quadrature for functions of limited regularity [PDF]
, 2012 We study the optimal general rate of convergence of the n-point quadrature rules of Gauss and Clenshaw-Curtis when applied to functions of limited regularity: if the Chebyshev coefficients decay at a rate O(n^{-s-1}) for some s > 0, Clenshaw-Curtis and ...

Coherent storage of temporally multimode light using a spin-wave atomic frequency comb memory
New Journal of Physics, 2013 We report on the coherent and multi-temporal mode storage of light using the full atomic frequency comb memory scheme. The scheme involves the transfer of optical atomic excitations in Pr ^3+ :Y _2 SiO _5 to spin waves in hyperfine levels using strong ...

Scalar field evolution in Gauss-Bonnet black holes
, 2005 It is presented a thorough analysis of scalar perturbations in the background of Gauss-Bonnet, Gauss-Bonnet-de Sitter and Gauss-Bonnet-anti-de Sitter black hole spacetimes. The perturbations are considered both in frequency and time domain.
