Journal of MathematicsNanostar dendrimers are tree-like nanostructures with a well-defined, symmetrical architecture. They are built in a step-by-step, controlled synthesis process, with each layer or generation building on the previous one.

Localization in a quasiperiodic model on quantum graphs [PDF]
In the book P. Exner et al. (Eds): Analysis on Graphs and its
Applications (Proc. Symp. Pure Math., vol. 77, AMS, 2008), pp. 459-467, 2007 We show the presence of a dense pure point spectrum on quantum graphs with Maryland-type quasiperiodic Kirchhoff coupling constants at the vertices.

BRST cohomology of the sum of two pure spinors [PDF]
arXiv, 2013 We study the zero mode cohomology of the sum of two pure spinors. The knowledge of this cohomology allows us to better understand the structure of the massless vertex operator of the Type IIB pure spinor superstring.

Second Phase transition line [PDF]
arXiv, 2016 We study the phase transion line of the almost Mathieu operator, that separates arithmetic regions corresponding to singular continuous and a.e. pure point regimes, and prove that both purely singular continuous and a.e. pure point spectrum occur for dense sets of frequencies.
