Critical Trapped Surfaces Formation in the Collision of Ultrarelativistic Charges in (A)dS
I. Ya. Aref'eva, A. A. Bagrov, L. V. Joukovskaya
We study the formation of marginally trapped surfaces in the head-on collision of two ultrarelativistic charges in space-time. The metric of ultrarelativistic charged parti…
Null Energy Condition Violation and Classical Stability in the Bianchi I Metric
Irina Ya. Aref'eva, Nikolay V. Bulatov, Liudmila V. Joukovskaya +1
The stability of isotropic cosmological solutions in the Bianchi I model is considered. We prove that the stability of isotropic solutions in the Bianchi I metric for a positive Hu…
Dynamics with Infinitely Many Time Derivatives in Friedmann-Robertson-Walker Background and Rolling Tachyon
Liudmila Joukovskaya
Open string field theory in the level truncation approximation is considered. It is shown that the energy conservation law determines existence of rolling tachyon solution. The cou…
Rolling Solution for Tachyon Condensation in Open String Field Theory
Liudmila Joukovskaya
Open string field theory in the level truncation approximation is considered. It is shown that the energy conservation law determines the existence of rolling tachyon solution. The…
Dynamics in nonlocal linear models in the Friedmann-Robertson-Walker metric
I. Ya. Aref'eva, L. V. Joukovskaya, S. Yu. Vernov
A general class of cosmological models driven by a nonlocal scalar field inspired by the string field theory is studied. Using the fact that the considering linear nonlocal model i…
Rolling Tachyon in Nonlocal Cosmology
L. Joukovskaya
Nonlocal cosmological models derived from String Field Theory are considered. A new method for constructing rolling tachyon solutions in the FRW metric in two field configuration i…
