Vacua Landscape Attractor
Alvaro Nunez, Slava Solganik
The recent progress in the understanding of the landscape of string theory vacua hints that the hierarchy problem might be the problem of a super-selection rule. The attractor mech…
Ghost Constraints on Modified Gravity
Alvaro Nunez, Slava Solganik
We show that general infrared modifications of the Einstein-Hilbert action obtained by addition of curvature invariants are not viable. These modifications contain either ghosts or…
The content of f(R) gravity
Alvaro Nunez, Slava Solganik
We analyze the propagating degrees of freedom in gravity models where the scalar curvature in the action is replaced by a generic function of the curvature. That these gravi…
Rolling Tachyon and Fields on the Brane
S. Solganik
This paper has been withdrawn by the author.
D-brane Inflation
G. Dvali, Q. Shafi, S. Solganik
We discuss a calculable version of brane inflation, in which a set of parallel D-brane and anti-D-brane worlds, initially displaced in extra dimension, slowly attract each other. I…
Topological Effects in Medium
A. N. Sissakian, O. Yu. Shevchenko, S. B. Solganik
Two closely related topological phenomena are studied at finite density and temperature. These are chiral anomaly and Chern--Simons term. It occurs that the chiral anomaly doesn't…
