ŝl(2)−1/2 AND THE TRIPLET MODEL
نویسنده
چکیده
Conformal field theories with ŝl(2)−1/2 symmetry are studied with a view to investigating logarithmic structures. Applying the parafermionic coset construction to the non-logarithmic theory, a part of the structure of the triplet model is uncovered. In particular, the coset theory is shown to admit the triplet W -algebra as a chiral algebra. This motivates the introduction of an augmented ŝl(2)−1/2-theory for which the corresponding coset theory is precisely the triplet model. This augmentation is envisaged to lead to a precise characterisation of the “logarithmic lift” of the non-logarithmic ŝl(2)−1/2-theory that has been proposed by Lesage et al.

FUSION IN FRACTIONAL LEVEL ŝl(2)-THEORIES WITH k =−
The fusion rules of conformal field theories admitting an ŝl(2)-symmetry at level k = − 1 2 are studied. It is shown that the fusion closes on the set of irreducible highest weight modules and their images under spectral flow, but not when “highest weight” is replaced with “relaxed highest weight”. The fusion of the relaxed modules, necessary for a well-defined û(1)-coset, gives two families of...
متن کاملŝl(2)−1/2: A CASE STUDY
The construction of the non-logarithmic conformal field theory based on ŝl(2)−1/2 is revisited. Without resorting to free-field methods, the determination of the spectrum and fusion rules is streamlined and the βγ ghost system is carefully derived as the extended algebra generated by the unique finite-order simple current. A brief discussion of modular invariance is given and the Verlinde formu...
متن کاملCoumarin phosphorescence observed with N^N Pt(II) bisacetylide complex and its applications for luminescent oxygen sensing and triplet-triplet-annihilation based upconversion.
A dbbpy platinum(II) bis(coumarin acetylide) complex (Pt-1, dbbpy = 4,4'-di-tert-butyl-2,2'-bipyridine) was prepared. Pt-1 shows intense absorption in the visible region (λ(abs) = 412 nm, ε = 3.23 × 10(4) M(-1) cm(-1)) compared to the model complex dbbpy Pt(II) bis(phenylacetylide) (Pt-2, λ(abs) = 424 nm, ε = 8.8 × 10(3) M(-1) cm(-1)). Room temperature phosphorescence was observed for Pt-1 ((3)...
متن کاملElectric-Field-Induced Triplet to Singlet Transition in Size-2 Trigonal Zigzag Graphene Nanoflake
Using Hartree-Fock Su-Sheriffer-Heeger (HF-SSH) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 NF) on the intensity of an external in plane static electric field at zero temperature. We identify a transition from the magnetic triplet stat...
متن کاملPhenomenology of a Su(2) Triplet
We study the Renormalization Group (RG) evolution of the couplings in a model with a real SU(2) triplet in the Higgs sector. Insisting that the model remain valid up to 1 TeV we show that it is possible for there to be no light Higgs bosons without any otherwise dramatic deviation from the physics of the Standard Model.
