WebApr 16, 2001 · The tachyon equation Let us now examine the space of solutions of the linearized equation of motion and check whether on shell there are elements of our functional space of well-defined fluctuations. We shall write the wave equations (following the conventions of [9] ) as: (45) ∇ 2 T−2∇ A Φ∇ A T−m 2 T=0. WebMar 15, 2007 · The free energy of the system decreases in the direction of larger N or later times, thus defining a thermodynamic arrow of time. Time evolution equations are mapped to differential equations relating thermal expectation values of certain observables at different points of thermal equilibrium.

Webterm of the tachyon field has a form suggested by string theory (see the review [12]and references therein). One can also mention models where the role of dark energy is played by quantum corrections to the effective action of a scalar field [13]. Here we consider a recently proposed class of simple cosmological Webanswered Oct 20, 2014 at 4:35. Hypnosifl. 6,130 2 23 38. Add a comment. 12. In addition to the Hypnosifl's answer: in lots of modern theories tachyons do not violate causality. For example, in QFT you can choose the mass-squared term in the action to have a negative sign, that would make your field's quanta tachyons. WebIn special relativity the equation of motion for the tachyon is: f i = m t c 2 (du i /ds) where the space components of the 4-vector f i form a 3-vector f / (1-v 2 /c 2) 1/2, the time component is f 4 = i f ( v /c)/ (1-v 2 /c 2) 1/2 .
