A semi-discrete numerical scheme for nonlocally regularized KdV-type equations
(Elsevier, 2022-05)A general class of KdV-type wave equations regularized with a convolution-type nonlocality in space is considered. The class differs from the class of the nonlinear nonlocal unidirectional wave equations previously studied ... -
Size dependent change of mean square displacement in gold nanocrystals: A molecular dynamics simulation
(Wiley, 2023-11-01)Thermally activated atomic vibrations significantly decrease the x-ray diffraction intensities of nanocrystalline powders. Hence their quantification is critical for accurate structural characterization of small nanocrystals ... -
Some remarks on the stability and instability properties of solitary waves for the double dispersion equation

String analog of Reissner–Nordström black holes cannot be overcharged
(World Scientific Publishing Co Pte Lt, 2019-09-28)In this work, we attempt to overcharge extremal and nearly extremal charged black holes in string theory, known as the Garfinkle-Horowitz-Strominger solution. We first show that extremal black holes cannot be overcharged ... -
Structure and dynamics of charmed baryons in lattice QCD
