Self-similarity and singularity formation in a coupled system of Yang-Mills-dilaton evolution equations
E. E. Donets, O. I. Streltsova, T. L. Boyadjiev
We study both analytically and numerically a coupled system of spherically symmetric SU(2) Yang-Mills-dilaton equation in 3+1 Minkowski space-time. It has been found that the syste…
Brane Vacuum as Chain of Rotators
E. E. Donets, A. P. Isaev, C. Sochichiu +1
We analyse the noncommutative U(1) sigma model, which arises from the vacuum dynamics of the noncommutative charged tachyonic field. The sector of ``spherically symmetric'' excitat…
N=4 Superconformal Mechanics and the Potential Structure of AdS Spaces
E. E. Donets, A. Pashnev, V. O. Rivelles +2
The dynamics of an N=4 spinning particle in a curved background is described using the N=4 superfield formalism. The N=4 superconformal symmetr…
Partial supersymmetry breaking in Multidimensional N=4 SUSY QM
E. E. Donets, A. Pashnev, J. J. Rosales +1
The multidimensional N=4 supersymmetric quantum mechanics (SUSY QM) is constructed and the various possibilities for partial supersymmetry breaking are discussed. It is shown that…
N=4 Supersymmetric Multidimensional Quantum Mechanics, Partial SUSY Breaking and Superconformal Quantum Mechanics
E. E. Donets, A. Pashnev, J. Juan Rosales +1
The multidimensional N=4 supersymmetric quantum mechanics (SUSY QM) is constructed using the superfield approach. As a result, the component form of the classical and quantum Lagra…
Evolution of Nonlinear Perturbations Inside Einstein-Yang-Mills Black Holes
E. E. Donets, M. N. Tentyukov, M. M. Tsulaia
We present our results on numerical study of evolution of nonlinear perturbations inside spherically symmetric black holes in the SU(2) Einstein-Yang-Mills (EYM) theory. Recent dev…
