Catalysis of Black Holes/Wormholes Formation in High Energy Collisions
I. Ya. Aref'eva
We discuss various mechanisms of catalysis of black holes/wormholes (BH/WH) formation in particles collisions. The current paradigm suggests that BH/WH formation in particles colli…
Stable Exact Solutions in Cosmological Models with Two Scalar Fields
Irina Ya. Aref'eva, Nikolay V. Bulatov, Sergey Yu. Vernov
The stability of isotropic cosmological solutions for two-field models in the Bianchi I metric is considered. We prove that the sufficient conditions for the Lyapunov stability in…
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…
Pure Gauge Configurations and Tachyon Solutions to String Field Theories Equations of Motion
I. Ya. Aref'eva, R. V. Gorbachev, D. A. Grigoryev +3
In constructions of analytical solutions to open string field theories pure gauge configurations parameterized by wedge states play an essential role. These pure gauge configuratio…
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…
