A quadratic formula for basic hypergeometric series related to Askey-Wilson polynomials
Victor J. W. Guo, Masao Ishikawa, Hiroyuki Tagawa +1
We prove a general quadratic formula for basic hypergeometric series, from which simple proofs of several recent determinant and Pfaffian formulas are obtained. A special case of t…
Momentum Dependent Local-Ansatz Wavefunction from Weak to Strong Electron Correlations
M. Atiqur R. Patoary, Sumal Chandra, Yoshiro Kakehashi
Momentum dependent local-ansatz (MLA) wavefunction describes accurately electron correlations from the weak to intermediate Coulomb interaction regimes. We point out that the MLA c…
New code for equilibriums and quasiequilibrium initial data of compact objects. II. Convergence tests and comparisons of binary black hole initial data
Koji Uryu, Antonios Tsokaros, Philippe Grandclement
COCAL is a code for computing equilibriums or quasiequilibrium initial data of single or binary compact objects based on finite difference methods. We present the results of supple…
Nonlocal Excitations and 1/8 Singularity in Cuprates
Yoshiro Kakehashi, M. Atiqur R. Patoary, Sumal Chandra
Momentum-dependent excitation spectra of the two-dimensional Hubbard model on the square lattice have been investigated at zero temperature on the basis of the full self-consistent…
Binary black hole circular orbits computed with COCAL
Antonios Tsokaros, Koji Uryu
In this work we present our first results of binary black hole circular orbits using {\sc cocal}, the Compact Object CALculator. Using the 3+1 decomposition five equations are bein…
Neutron scattering experiments and simulations near the magnetic percolation threshold of Fe_x Zn_{1-x} F_2
G. Alvarez, N. Aso, D. P. Belanger +4
The low temperature excitations in the anisotropic antiferromagnetic Fe_{1-x} Zn_x F_2 for x=0.25 and 0.31, at and just above the magnetic percolation threshold concentration x_p=0…
