Configuration interaction calculation for the isotope shift in Mg I

J. C. Berengut, V. A. Dzuba, V. V. Flambaum +1

We present an ab initio method of calculation of isotope shift in atoms with a few valence electrons, based on the configuration-interaction calculation of energy. The main motivat…

The 2dF Galaxy Redshift Survey: Wiener Reconstruction of the Cosmic Web

Pirin Erdogdu, Ofer Lahav, Saleem Zaroubi +27

We reconstruct the underlying density field of the 2 degree Field Galaxy Redshift Survey (2dFGRS) for the redshift range 0.035<z<0.200 using the Wiener Filtering method. The Wiener…

Thermodynamics of a one-dimensional S=1/2 spin-orbital model

J. Sirker

The thermodynamic properties of a one-dimensional model describing spin dynamics in the presence of a twofold orbital degeneracy are studied numerically using the transfer-matrix r…

Exponential enhancement of nuclear reactions in condensed matter environment

M. Yu. Kuchiev, B. L. Altshuler, V. V. Flambaum

A mechanism that uses the environment to enhance the probability of the nuclear reaction when a beam of accelerated nuclei collides with a target nucleus implanted in condensed mat…

Conformal geometry of the (discrete) Schwarzian Davey-Stewartson II hierarchy

B. G. Konopelchenko, W. K. Schief

The conformal geometry of the Schwarzian Davey-Stewartson II hierarchy and its discrete analogue is investigated. Connections with discrete and continuous isothermic surfaces and g…

Scattering of scalar particles by a black hole

M. Yu. Kuchiev, V. V. Flambaum

The absorption cross section for scalar particle impact on a Schwarzschild black hole is found. The process is dominated by two physical phenomena. One of them is the well-known gr…
