High-Quality Ultra-Fast Total Scattering and Pair Distribution Function Data using an X-ray Free Electron Laser
Adam F. Sapnik, Philip A. Chater, Dean S. Keeble +48
High-quality total scattering data, a key tool for understanding atomic-scale structure in disordered materials, require stable instrumentation and access to high momentum transfer…
Integral filling volume, complexity and integral simplicial volume of 3-dimensional mapping tori
Federica Bertolotti, Roberto Frigerio
We show that the integral filling volume of a Dehn twist on a closed oriented surface vanishes, i.e. that the integral simplicial volume of the mapping torus with monodromy $f^…
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…
Insight into Non Linearly Shaped Superconducting Whiskers via Synchrotron Nanoprobe
Stefano Cagliero, Elisa Borfecchia, Lorenzo Mino +8
We managed to synthesize non-linear YBa2Cu3Ox whiskers, i.e. half loops or kinked shapes, which are promising candidates for solid-state devices based on the intrinsic Josephson ef…
