Cerenkov radiation from moving straight strings
D. V. Gal'tsov, E. Yu. Melkumova, K. Salehi
We study Cerenkov radiation from moving straight strings which glisse with respect to each other in such a way that the projected intersection point moves faster than light. To cal…
Radiation reaction in curved space-time: local method
Dmitri Gal'tsov, Pavel Spirin, Simona Staub
Although consensus seems to exist about the validity of equations accounting for radiation reaction in curved space-time, their previous derivations were criticized recently as not…
Cylindrically symmetric solitons in Einstein-Yang-Mills theory
Dmitri V. Gal'tsov, Evgeny A. Davydov
Recently new Einstein-Yang-Mills (EYM) soliton solutions were presented which describe superconducting strings with Kasner asymptotic (hep-th/0610183). Here we study the static cyl…
Cerenkov radiation from collisions of straight cosmic (super)strings
Elena Melkumova, Dmitri Gal'tsov, Karim Salehi
We consider Cerenkov radiation which must arise when randomly oriented straight cosmic (super)strings move with relativistic velocities without intercommutation. String interaction…
Dilaton and axion bremsstrahlung from collisions of cosmic (super)strings
E. Yu. Melkumova, D. V. Gal'tsov, K. Salehi
We calculate dilaton and axion radiation generated in the collision of two straight initially unexcited strings and give a rough cosmological estimate of dilaton and axion densitie…
Einstein--Yang--Mills strings
Dmitri V. Gal'tsov, Evgeny A. Davydov, Mikhail S. Volkov
We present globally regular vortex-type solutions for a pure SU(2) Yang-Mills field coupled to gravity in 3+1 dimensions. These gravitating vortices are static, cylindrically symme…
