WebAug 13, 2002 · This field theory realizes two known properties of the tachyon effective action: (a) absence of plane-wave solutions around the minimum, and (b) exponential fall off of the pressure at late time as the tachyon field evolves from any spatially homogeneous initial configuration towards the minimum of the potential. WebOct 11, 2004 · We also describe various attempts to understand these results using field theoretic methods. 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.
WebTachyon theory states that the Tachyon universe continually creates, sustains and energizes the physical universe. Every created thing owes its existence to the expansion of the … WebOct 30, 2013 · A test particle falling towards the event horizon of a non-extreme black hole can actually be viewed as an unstable particle, whose dynamics is described by the tachyon field theory. This means that the collapsing process of a free particle in Rindler space is essentially a tachyon condensation process.
