Lattice deformations couple to electrons in graphene by giving rise to an effective gauge field [1,2]. This unique feature leads to the possibility of modifying the electronic properties by applying strain to the lattice [3,4]. The main properties...

The shortest path tour problem (SPTP) consists of finding a shortest path from a given origin node s to a given destination node d in a directed graph with nonnegative arc lengths with the constraint that the optimal path P should successively and...
2010-09-14I will presents new observational tests of the LCDM paradigm. In particular I will focus on the following questions: are there universal dark matter profiles? is there dark matter substructure? What is the equation of state of dark energy? I wil...
2010-09-10"True consent", as Bacon has it, "is that which consists in the coincidence of free judgements after due examination". However, as Montessori has it, "we cannot be free if we are not independent". The persistence of economic hardship, where nation...
2010-07-16Viene presentato un approccio alla teoria dell'operatore $\overline\partial$ su spazi con singolarità tramite il concetto di corrente metrica (Ambrosio, Kirchheim - 2000). Verranno illustrati alcuni risultati locali nel caso di particolari singo...
2010-07-14Recent experimental observations have shown that quantum coherence plays an important role in photosynthetic energy transport. Photosynthetic molecules are large and complex, containing both regular structures, such as rings of chromophores, and appa...
