Comments on the Fate of unstable orbifolds
نویسنده
چکیده
We study the localized tachyon condensation in their mirror Landau-Ginzburg picture. We completely determine the decay mode of an unstable orbifold C/Zn, r = 1, 2, 3 under the condensation of a tachyon with definite R-charge and mass by extending the Vafa’s work hep-th/0111105. Here, we give a simple method that works uniformly for all C/Zn. For C/Zn, where method of toric geometry works, we give a proof of equivalence of our method with toric one. For C/Zn cases, the orbifolds decay into sum of r far separated orbifolds. Work supported partially by the department of Energy under contract number DE-AC03-76SF005515. Permanent address

Peer Reviewers’ Comments on Research Articles Submitted by Iranian Researchers
The invisible hands of peer reviewers play a determining role in the eventual fate of submissions to international English-medium journals. This study builds on the assumption that non-native researchers and prospective academic authors may find the whole strive for publication, and more specifically, the tough review process, less threatening if they are aware of journal reviewers’ expectation...
متن کاملComments on Condensates in Non-Supersymmetric Orbifold Field Theories
Non-supersymmetric orbifolds of N = 1 super Yang-Mills theories are conjectured to inherit properties from their supersymmetric parent. We examine this conjecture by compactifying the Z2 orbifold theories on a spatial circle of radius R. We point out that when the orbifold theory lies in a specific weakly coupled vacuum, fractional instantons do give rise to the conjectured condensate of bi-fun...
متن کاملOn Dimer Models and Closed String Theories
We study some aspects of the recently discovered connection between dimer models and D-brane gauge theories. We argue that dimer models are also naturally related to closed string theories on non compact orbifolds of C2 and C3, via their twisted sector R charges, and show that perfect matchings in dimer models correspond to twisted sector states in the closed string theory. We also use this for...
متن کاملOrbifolds as Melvin Geometry
In this paper we explicitly show that the various noncompact abelian orbifolds are realized as special limits of parameters in type II (NSNS) Melvin background and its higher dimensional generalizations. As a result the supersymmetric ALE spaces (A-type C2/ZN ) and nonsupersymmetric orbifolds in type II and type 0 theory are all connected with each other by the exactly marginal deformation. Our...
متن کاملDecay Rates of Fixed Planes and Closed-string Tachyons on Unstable Orbifolds
We consider closed-string tachyon condensation in the twisted sectors onC/Z2n+1× R 7,1 orbifold. We calculate the localized energy density at the fixed plane on the orbifold at the one-loop level, and we obtain the decay rate per unit volume of the fixed plane at the leading order. We show that the decay rate increases monotonically as n grows. ∗[email protected]
