Improved effective-range expansions for small and large values of scattering length
(2018-08-14)
The textbook effective-range expansion of scattering theory is useful in the analysis of low-energy scattering phenomenology when the scattering length |a| is much larger than the range R of the scattering potential: |a| ...
Comment on: “Ground state energies from converging and diverging power series expansions”, Ann. Phys. 373 (2016) 456–469
(Academic Press Inc Elsevier Science, 2017-01)
We compare two alternative expansions for finite attractive wells. One of them is known from long ago and is given in terms of powers of the strength parameter. The other one is based on the solution of the equations of ...
Unified formulation of variational approaches and separable expansions for the solution of scattering equations
(1987-01-01)
Both the variational approach and the method of separable expansion have proved to be very useful for the solution of scattering equations. Connections are established between these two approaches. It is shown that an ...
Expansion of a Bose-Einstein condensate formed on a joint harmonic and one-dimensional optical-lattice potential
(Iop Publishing Ltd, 2003-10-14)
We study the expansion of a Bose-Einstein condensate trapped in a combined optical-lattice and axially-symmetric harmonic potential using the numerical solution of the mean-field Gross-Pitaevskii equation. First, we consider ...

Electrostatic interaction due to patch potentials on smooth conducting surfaces
(American Physical Society, 2013-12)
We evaluate the electrostatic interaction energy between two surfaces, one flat and the other slightly curved, in terms of the two-point autocorrelation functions for patch potentials on each one of them, and of a single ...
Quaternary range and demographic expansion of Liolaemus darwinii (Squamata: Liolaemidae) in the Monte Desert of Central Argentina using Bayesian phylogeography and ecological niche modelling
(Wiley, 2013-06-20)
Until recently, most phylogeographic approaches have been unable to distinguís between demographic and range expansion processes, making it difficult to test for the possibility of range expansion without population growth ...
