Twisting instabilities in elastic ribbons with inhomogeneous pre-stress: A macroscopic analog of thermodynamic phase transition

Pedro Miguel Nunes Pereira de Almeida Reis, Michael Christopher Gomez

We study elastic ribbons subject to large, tensile pre-stress confined to a central region within the cross-section. These ribbons can buckle spontaneously to form helical shapes, featuring regions of alternating chirality (phases) that are separated by so ...

Temperature- and pressure-dependence of the hydrogen bond network in plastic ice VII

Livia Eleonora Bove Kado, Umbertoluca Ranieri, Maria Rescigno

We model, via classical molecular dynamics simulations, the plastic phase of ice VII across a wide range of the phase diagram of interest for planetary investigations. Although structural and dynamical properties of plastic ice VII are mostly independent o ...

Transferable machine-learning models of complex materials: the case of GaAs

Giulio Imbalzano

Molecular simulations allow to investigate the behaviour of materials at the atomistic level, shedding light on phenomena that cannot be directly observed in experiments. Accurate results can be obtained with ab initio methods, while simulations of large-s ...

Multithermal-Multibaric Molecular Simulations from a Variational Principle

Pablo Miguel Piaggi

We present a method for performing multithermal-multibaric molecular dynamics simulations that sample entire regions of the temperature-pressure (TP) phase diagram. The method uses a variational principle [Valsson and Parrinello, Phys. Rev. Lett. 113, 0906 ...

Magnetic and thermodynamic properties of CuxTiSe2 single crystals

Helmuth Berger

We present a detailed study of the phase diagram of copper-intercalated TiSe2 single crystals, combining local Hall-probe magnetometry, tunnel diode oscillator technique (TDO), and specific-heat and angle-resolved photoemission spectroscopy measurements. A ...

Experimental study and thermodynamic description of the Au-Cu-Ge system

Christian Leinenbach, Shan Jin

Phase equilibria in the Au-Cu-Ge ternary system, including the solid state phase relations at 450 degrees C as well as four vertical sections, were studied by means of scanning electron microscopy (SEM), electron probe microanalysis (EPMA), X-ray diffracti ...

Topological pumping in class-D superconducting wires

Marco Gibertini

We study adiabatic pumping at a normal metal/class-D superconductor hybrid interface when superconductivity is induced through the proximity effect in a spin-orbit coupled nanowire in the presence of a tilted Zeeman field. When the induced order parameter ...

Temperature-Dependent Ordering Phenomena of a Polyiodide System in a Redox-Active Ionic Liquid

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Jan Cornelius Brauer

Iodine added to iodide-based ionic liquids leads to dramatic changes of their physical properties which may have implications for technological applications. Here we study the phase diagram of 1-methyl 3-propylimidazolium iodide, the temperature versus iod ...

Spinodal surface of a free energy model for eye lens protein mixtures: Relevance for cataracts

Giuseppe Foffi, Nicolas Dorsaz

We studied the phase behavior of a model binary mixture of eye lens crystallin proteins using first-order thermodynamic perturbation theory. The instability boundary, or spinodal surface, was found to be very sensitive to the strength of the attraction bet ...
