Casimir energy of a non-uniform string
L. Hadasz, G. Lambiase, V. V. Nesterenko
The Casimir energy of a non-uniform string built up from two pieces with different speed of sound is calculated. A standard procedure of subtracting the energy of an infinite unifo…
The vortex oscillations in Abelian Higgs model
J. Karkowski, Z. Swierczynski
The excitations of the vortex in Abelian Higgs model with small ratio of vector and Higgs particle masses are considered. Three main modes encountered in numerical computations are…
High energy scattering and the AdS/CFT correspondence
R. A. Janik, R. Peschanski
We consider small angle and large impact parameter high energy scattering of colourless states in SYM using the AdS/CFT correspondence. The gauge theory scattering amplitude is lin…
Casimir energy of the Nambu-Goto string with Gauss-Bonnet term and point-like masses at the ends
Leszek Hadasz
We calculate (using zeta function regularization) the Casimir energy of the rotating Nambu-Goto string with the Gauss-Bonnet term in the action and point-like masses at the ends. T…
