We discuss the localized tachyon condensation in the non-supersymmetric orbifold theories by taking the cosmological constant as the measure of degrees of freedom. We show that both localized and delocalized degrees of freedom encode information on the process of localized tachyon condensation: the former encodes in the c-function given by the lightest tachyon mass, and the latter in the g-func...

We discuss the localized tachyon condensation in the non-supersymmetric orbifold theories by taking the cosmological constant as the measure of degrees of freedom (d.o.f). We first show asymptotic density of state is not a proper quantity to count the ’localized’ d.o.f. We then show that localized d.o.f lead us a c-function given by the lightest tachyon mass, which turns out to be the same as t...

متن کاملCounting statistics for mesoscopic conductors with internal degrees of freedom.
We consider the transport of electrons passing through a mesoscopic device possessing internal dynamical quantum degrees of freedom. The mutual interaction between the system and the conduction electrons contributes to the current fluctuations, which we describe in terms of full counting statistics. We identify conditions where this discriminates coherent from incoherent internal dynamics and a...
متن کاملLocalized tachyon mass and a g-theorem analogue
We study the localized tachyon condensation (LTC) of non-supersymmetric orbifold backgrounds in their mirror Landau-Ginzburg picture. Using he existence of four copies of (2,2) worldsheet supersymmetry, we show at the CFT level, that the minimal tachyon mass in twisted sectors shows somewhat analogous properties of cor g-function. Namely, m := |α′M2 min| satisfies m(M) ≥ m(D1 ⊕D2) = max{m(D1),m...
