Experimental results concerning magnetic susceptibility and heat capacity of the CuSb2O6 crystal, where the Cu2+ ions form chains interacting with strong short range antiferromagnetic (AF) intrachain and weak AF interchain interactions, can be interpreted in terms of small rings to which the...

For a diatomic molecule system in Morse potential the eigenfunctions and eigenvalues have been found by supersymmetric quantum mechanics (SQM) approach. The result has shown that Morse potential is shape invariance. A method identifying the Morse potential according to the energy spectrum of...

In order to manufacture parts with dimensions of nanometres, high–technology equipment is required. There is a demand to study nano-metric cutting mechanisms and phenomena appearing in this level. However, experiments are difficult to be realized, so computational methods are employed....
