2021 Symmetry  
This paper presents our study of the presence of the unstable critical point in spontaneous symmetry breaking (SSB) in the framework of Ginzburg–Landau (G-L) free energy.  ...  In scalar field theories, such as Higgs fields, the mass of this soliton inside the hysteresis zone could behave as a tachyon mass, namely as an imaginary quantity.  ...  Conflicts of Interest: The authors declare no conflict of interest.

Corpuscular Breaking of Supersymmetry [article]

Gia Dvali, Cesar Gomez
2014 arXiv   pre-print
The extension of the corpuscular structure to D-branes can lead to a built-in supersymmetry breaking mechanism in string theory, insensitive to technicalities such as moduli stabilization, with the SUSY  ...  Corpuscular corrections are stronger and appear already at order √(ħ g^2). In SUSY theories quantum corpuscular corrections generically break supersymmetry.  ...  The work of C.G. was supported in part by Humboldt Foundation and by Grants: FPA 2009-07908, CPAN (CSD2007-00042) and HEPHACOS P-ESP00346 and by the ERC Advanced Grant 339169 "Selfcompletion" .  ...

Spacelike branes

Michael Gutperle, Andrew Strominger
2002 Journal of High Energy Physics  
It is argued that such S-branes arise in string theory as time-dependent solutions of the worldvolume tachyon field of an unstable D-brane or D-brane-anti-D-brane pair.  ...  Using the known coupling of the spacetime RR fields to the worldvolume tachyon it is shown that these S-branes carry a charge, defined as the integral of a RR field strength over a sphere (containing a  ...  It is conceivable that this might be describable as spontaneous R-symmetry breaking in an S-brane field theory.  ...

Relativity 4-ever?

Olga Chashchina, Zurab Silagadze
2022 Physics  
Tachyons are breafly discussed and it is explained that, due to internal instability, tachyon fields cannot be used to transmit information faster than the speed of light.  ...  It is generally believed that special relativity prohibits movements faster than the speed of light. It is explained which motion is actually forbidden by special relativity and why.  ...  Our special respects to Oksana Akinshina, a Russian actress who played the main role. Conflicts of Interest: The authors declare no conflict of interest.  ...

Breaking the light speed barrier [article]

O. I. Chashchina, Z. K. Silagadze
2012 arXiv   pre-print
In quantum field theory, the appearance of tachyonic degrees of freedom indicates vacuum instability rather than a real existence of the faster-than-light particles.  ...  Driven by a striking analogy of the old Frenkel-Kontorova model of a dislocation dynamics to the theory of relativity, we conjecture in this note a remarkable possibility of existence of the fourth type  ...  Summing up, tachyons do exist and play a significant role in modern quantum theory (virtual particles, spontaneous symmetry breaking, string theory).  ...

Supersymmetric brane–antibrane configurations

Adopting the matrix theory description, we construct the worldvolume gauge theories and prove the absence of any tachyonic degrees.

Another Length Scale in String Theory? [article]

Stephen H. Shenker
1995 arXiv   pre-print
We suggest that some of the remarkable results on stringy dynamics which have been found recently indicate the existence of another dynamical length scale in string theory that, at weak coupling, is much  ...  This additional scale corresponds to a mass ∼ m_ s/g_ s where m_ s is the square root of the string tension and g_ s is the string coupling constant.  ...  The dilaton can be completely eliminated from the Lagrangian by going to Einstein frame and rescaling the RR fields so they are quantized in unit strength.  ...
