WebMay 14, 2002 · Problems with Tachyon Inflation. We consider cosmological consequences of string theory tachyon condensation. We show that it is very difficult to obtain inflation in the simplest versions of this theory. Typically, inflation in these theories could occur only at super-Planckian densities, where the effective 4D field theory is inapplicable.

Webtachyon, hypothetical subatomic particle whose velocity always exceeds that of light. The existence of the tachyon, though not experimentally established, appears consistent with the theory of relativity, which was originally thought to apply only to particles traveling at or less than the speed of light.

We show that the equation of state of this “modified Chaplygin” gas can describe the current accelerated expansion of the universe.

WebJul 27, 2024 · In field theory the imaginary mass of tachyons appears when the symmetry is broken. In order for a soliton to present the same behavior as the tachyon, it must also show imaginary mass because it appears in the phase of the broken symmetry.

These field theory models include toy models like singular potential models and p-adic string theory, as well as more realistic version of the tachyon effective action based on Dirac-Born-Infeld type action. Web2. Polchinski explains the state-operator correspondence in section 2.8, in particular equations 2.8.3, 2.8.4, and 2.8.9. What you call "higher vertex operators" create multiple particles (if there are multiple exponential vertex operators) with higher spin (if there are extra derivatives multiplying the exponentials).
