Homotopy Equivalences of 3-Manifolds
Federica Bertolotti
Let be an oriented closed -manifold. We prove that there exists a constant , depending only on the manifold , such that for every self-homotopy equivalence of $M…

Length functions on mapping class groups and simplicial volumes of mapping tori
Federica Bertolotti, Roberto Frigerio
Let be a closed orientable manifold. We introduce two numerical invariants, called filling volumes, on the mapping class group of , which are defined in te…

Phonon-Mediated Attractive Interactions between Excitons in Lead-Halide-Perovskites
Nuri Yazdani, Maryna I. Bodnarchuk, Federica Bertolotti +20
Understanding the origin of electron-phonon coupling in lead-halide perovskites (LHP) is key to interpreting and leveraging their optical and electronic properties. Here we perform…
