WebThe dynamics (in light-cone time) of the tachyon on an unstable brane in the background of a dilaton linear along a null coordinate is a non-local reaction-diffusion type equation, which admits a ... WebMar 10, 2024 · Since γ = 1 / / square root of (1 - v 2 /c 2), this is what causes the different look of the two equations shown. m 0 is the rest mass of the object, obtained when it has a velocity of 0 in a given frame of reference. c is the speed of light in free space. ... If a tachyon did exist, it would always move faster than the speed of light. Using ...

WebDear @truebeliever1234, a tachyon can't have a constant (in spacetime) vev because a constant vev doesn't satisfy the equations of motion, ( ∇ μ ∇ μ + m 2) T = 0. The first term with the derivatives drops for a constant T and the second one doesn't, so … WebI presume that the tachyonic nature follows if the notation of $ 0;k>$ follows the same state as described as the lightest bosonic open strings as in equation 1.3.38..) Though there does seem to be a need to derive 2.8.9 - but unlike these 3.6.1 and 3.6.25 are talking of "closed" strings.. $\endgroup$ horizon ignited merch

WebJan 8, 2003 · We obtain the relevant Dp-brane boundary state with electric and magnetic fields by boosting and rotating the rolling tachyon boundary state of a D (p-1)-brane and then T-dualizing along one of the transverse directions. A simple recipe to turn on the gauge fields in the boundary state is given. WebThen an approach is proposed to tachyon equations that is alternative to using (superluminal) Lorentz transformations, and it is shown that the tachyon physical laws can be guessed without reference to superluminal reference frame.
