A theoretical analysis of a series imidazole-based Y-shaped chromophores, D1–D8, is performed in order to investigate their non(linear) optical, fluorescence, and charge-transport properties. The calculations have been carried out employing DFT TD-DFT methods at CAM-B3LYP M06-2X levels theory. FMO reveals that ground state, the highest occupied molecular orbital localized on 4,5-dimethylanilino...

Starting from an already known solution in the literature, we study dynamical cobordism induced by backreaction of a non-supersymmetric, positive tension domain wall string theory. This could e.g. be non-BPS D8-brane type I or $\overline{D8}/O8$ stack non-supersymmetric IIA orientifold. The singularities which typically appear indicate either inherent inconsistency this background required pres...

We consider a D4 − D8 − D8 brane construction which gives rise to a large N QCD at sufficiently small energies. Using the gravity dual of this system, we study chiral phase transition at finite chemical potential and temperature and find a line of first order phase transitions in the phase plane. We compute the spectral function and the photon emission rate. The trace of the spectral function i...
