WebOct 16, 2006 · Warm inflationary universe models in a tachyon field theory are studied. General conditions required for these models to be realizable are derived and discussed. We describe scalar perturbations (in the longitudinal gauge) and tensor perturbations for these scenarios. We develop our models for a constant dissipation parameter Γ in one case and ... 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.

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.

WebAug 26, 2024 · quantum field theory of a tachyon. Field theories have been proposed for the singlet tachyon, represented by a scalar field. The first to attempt this was Tanaka.[7] As Tanaka noted, his model had difficulties with Lorentz-invariance: a Lorentz-invariant unique vacuum state did not exist, nor did an unitary operator implementing a 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.

WebIt is shown that in these models, a fermionic field takes a tremendous role in both the early universe inflation and the late-time universe dark energy. As inspired by the string theory, a tachyon field also produces inflation in the very early universe (Gibbons, 2002, Jentschura and Wundt, 2012, Saha, 2016, Salesi, 1997, Bandukwala and Shay ... 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.
