Microscopic origin of the Baumgärtel-Schausberger-Winter Relaxation Spectrum in Polymer Melts and Particle Rafts
Dario Nichetti, H. Henning Winter, Alessio Zaccone
Entangled polymer melts exhibit the robust two-branch Baumgärtel-Schausberger-Winter (BSW) relaxation spectrum, while related spectra occur in nonpolymeric monodisperse disordered…
Delayed Arm Retraction Controls the Nonlinear Oscillatory Response of Long-Chain-Branched Polymer Melts
Dario Nichetti, Alessio Zaccone
Long-chain branching profoundly modifies the nonlinear oscillatory response of entangled polymer melts by introducing arm-retraction pathways absent in linear polymers. We present…
The Physics of Topological Defects in Glasses
Arabinda Bera, Peter Schall, Timothy W. Sirk +2
Topological defects play a central role in the mechanical behavior of crystalline materials, yet their relevance to amorphous solids has only recently begun to emerge. Over the las…
Thermal rectification due to phonon confinement in nanoparticles
Alexej D. Semenov, Mariia Sidorova, Alessio Zaccone +1
We demonstrate that thermal rectification can arise at the contact between two spherical nanoparticles of identical material but different size due to the geometric confinement of…
Thermal Rectification from Size-Dependent Phonon Confinement in Nanoparticle Assemblies
Megan J. Farrington, David J. Wasserman, Eden R. Josza +6
Thermal insulation remains an important technological challenge across the vast number of applications, from living quarters to quantum technology. Here, we exploit the size-depend…
Constraint-Limited Tube Orientation of Entangled Polymers in Oscillatory Shear Deformation
Dario Nichetti, Alessio Zaccone
We develop a molecularly motivated description of the nonlinear index (NLI) in oscillatory shear deformation of entangled polymers. The central assumption is that the shear compone…
Local Structural Signatures of Shear Bands in Metallic Glasses via Electron Nanodiffraction
Huyen T. Pham, Daniel East, Chunguang Tang +4
Structural changes in a glass due to deformation are subtle and difficult to quantify using conventional imaging and diffraction techniques. Additionally, transmission electron mic…
Ginzburg-Landau Theory for Confined Thin-Film Superconductors
Giovanni A. Ummarino, Alessio Zaccone
We develop a Ginzburg-Landau theory for superconducting thin films under quantum confinement. Starting from the Ginzburg-Landau theory and the recently developed confinement theory…
Prediction of new superconducting bilayers heterostructures using quantum confinement and proximity effects
Giovanni A. Ummarino, Alessio Zaccone
A central challenge in nanoscale superconductivity is to understand and exploit the combined action of quantum confinement and proximity effects in experimentally realistic metalli…
