    A three step recipe for designing auxetic materials on demand
    (2022) Acuna, Daniel; Gutierrez, Francisco; Silva, Rodrigo; Palza, Humberto; Nunez, Alvaro S.; During, Gustavo
    Auxetics are an unusual family of materials that, for instance, when stretched in a particular direction will exhibit an expansion of the dimensions that are perpendicular to the applied stress; however, despite many known examples of auxectics there is no universal description of the material properties. Here, the authors report a model based on antiferromagnetic spins and demonstrate how this can be used to design a auxetic material with a Poisson ratio of -1 over a range of finite strain.

    Diverse intrusion modes during the construction of a high-silica magma reservoir: Evidence from La Obra-Cerro Blanco intrusive suite (central Chile)
    (2024) Payacan, Italo; Covarrubias, Maria Alejandra; Rodriguez, Nicolas; Tavazzani, Lorenzo; Gutierrez, Francisco; Roperch, Pierrick; Poblete, Fernando; Meyer, Martin
    Several conceptual models have been proposed for the amalgamation of granitoid plutons, which range from incremental growth to single-stage emplacement of these systems. This diversity of views has led to intense debate about the thermomechanical state of silicic intrusions and the magma differentiation paths within the crust. In this contribution, we present a comprehensive petrologic, geochronologic, and magnetic fabric data set from the La Obra-Cerro Blanco intrusive suite, which allows us to explore the petrogenesis and magma emplacement processes in the upper crust.
