- Tachyonic_field abstract "A tachyonic field, or simply tachyon, is a quantum field with an imaginary mass that represents an instability. The term "tachyon" was coined by Gerald Feinberg in a 1967 paper that studied quantum fields with imaginary mass. Feinberg believed such fields permitted faster than light propagation, but it was soon realized that Feinberg's model in fact did not allow for superluminal speeds, and instead that an imaginary mass causes an instability to a process known as tachyon condensation. Today, the term "tachyon" refers both to hypothetical particles that always move faster than light and to fields with imaginary mass. The latter have come to play an important role in modern physics and are discussed in popular books on physics.Due to the instability caused by the imaginary mass, any configuration in which one or more field excitations are tachyonic will spontaneously decay. In some cases this decay ends with another, stable configuration with no tachyons. A famous example is the condensation of the Higgs boson in the Standard Model of particle physics. Under no circumstances do any excitations ever propagate faster than light in such theories — the presence or absence of a tachyonic mass has no effect whatsoever on the maximum velocity of signals.In modern physics, all fundamental particles are regarded as localized excitations of fields. Tachyons are unusual because the instability prevents any such localized excitations from existing. Any localized perturbation, no matter how small, starts an exponentially growing cascade that strongly affects physics everywhere inside the future light cone of the perturbation.".
