In modern physics, all fundamental particles are regarded as excitations of quantum fields. There are several distinct ways in which tachyonic particles could be embedded into a field theory. In the paper that coined the term "tachyon", Gerald Feinberg studied Lorentz invariant quantum fields with imaginary mass. Because the group velocity for such a field is superluminal, naively it appears that its excitations propagate faster than light. However, it was quickly understood that … WebApr 20, 2004 · We begin with a lightning review of open string tachyon condensation, and then proceed to review recent results on localized closed string tachyon condensation, focusing on two simple systems, C/Z n orbifolds and twisted circle compactifications.

Closed string tachyon condensation: an overview

WebWe consider tachyon condensation in unstable ten-dimensional heterotic string theory with gauge group E 8. In the background of a lightlike linear dilaton rolling to weak coupling, we ﬁnd an exact solution in which the theory decays to a stable ground state. The ﬁnal WebMar 19, 2007 · We also investigate topological tachyon condensation, which enables us to construct, in a systematic fashion, higher-dimensional matrix factorizations out of smaller ones; this amounts to obtaining branes with higher RR charges as composites of ones with minimal charges. things to do in wicklow ireland

WebTachyon condensation is a process in particle physics in which a system can lower its energy by spontaneously producing particles. The end result is a "condensate" of particles that fills the volume of the system. Tachyon condensation is closely related to second-order phase transitions. things to do in wilburton ok

WebJun 21, 2001 · Motivated by recent discussions of actions for tachyon and vector fields related to tachyon condensation in open string theory we review and clarify some aspects of their derivation within the sigma model approach. In particular, we demonstrate that the renormalized partition function Z(T,A) of the boundary sigma model gives the effective … WebThe graph in the left panel shows a slight increase in tachyon condensation with the increasing quark mass, so the increase in the quark mass goes into confining the quarks at higher energies . Likewise, in the right panel, the tachyon condensation increases steadily as resulting into confinement at higher energy regimes. 5. Conclusions things to do in wickenburg todayWebA tachyon ( / ˈtækiɒn /) or tachyonic particle is a hypothetical particle that always travels faster than light. Physicists believe that faster-than-light particles cannot exist because they are not consistent with the known laws of physics.

WebJun 25, 2012 · The understanding of the closed string condensation is much less clear. Most likely, there doesn't exist any nearby local minimum and the potential for the closed string tachyon is unbounded from below in all directions, signalling a neverending instability that destroys the spacetime beyond repair. WebJul 5, 2001 · In a single brane scenario the tachyon potential is very steep and unable to support inflation. However if the universe lives in a stack of branes produced by a set of non-interacting unstable $\tilde {D4}$ branes, then the associated set of tachyons may drive inflation along our 3 spatial dimensions.
