Quantum Cosmology and Tachyons
We discuss the relevance of the classical and quantum rolling tachyons inflation in the frame of the standard, p-adic and adelic minisuperspace quantum cosmology. The field theory of tachyon matter proposed by Sen in a zero-dimensional version suggested by Kar leads to a model of a particle moving in a constant external field with quadratic damping. We calculate the exact quantum propagator of ...
متن کاملRolling Tachyons in String Cosmology
We study the role of rolling tachyons in the cosmological model with dilatonic gravity. In the string frame, flat space solutions of both initial-stage and late-time are obtained in closed form. In the Einstein frame, we show that every expanding solution is decelerating.
متن کاملWinding tachyons in BTZ
Analysing closed string tachyon condensation will improve our understanding of spacetime in string theory. We study the string spectrum on a BTZ black hole spacetime supported by NS-NS flux, which provides a calculable example where we would expect to find a quasi-localised tachyon. We find that there is a winding tachyon when the black hole horizon is smaller than the string scale, as expected...
متن کاملTachyons today
Much of my work as a Pappalardo Fellow has involved some puzzles that arise in certain string theories because of a very peculiar type of particle, called a tachyon. Here I’ll explain what a tachyon is and why it’s important to solve these puzzles. Along the way we’ll compare and contrast string theories with conventional particle theories. I should first clarify that when I say “theory” here I...
متن کاملInflation from Geometrical Tachyons
We propose an alternative formulation of tachyon inflation using the geometrical tachyon arising from the time dependent motion of a BPS D3-brane in the background geometry due to k parallel NS5-branes arranged around a ring of radius R. Due to the fact that the mass of this geometrical tachyon field is √ 2/k times smaller than the corresponding open-string tachyon mass, we find that the slow r...
