Accelerated Workflow for Antiperovskite-based Solid State Electrolytes
Andrea Fedrigucci, Ivano Eligio Castelli
We developed and implemented a multi-target multi-fidelity workflow to explore the chemical space of antiperovskite materials with general formula X(3)BA (X=Li, Na, Mg) and Pm-3m space group, searching for stable high-performance solid state electrolytes f ...
WILEY-V C H VERLAG GMBH2023Outer automorphism anomalies
We discuss anomalies associated with outer automorphisms in gauge theories based on classical groups, namely charge conjugations for SU(N) and parities for SO(2r). We emphasize the inequivalence (yet related by a flavor transformation) between two versions ...
SPRINGER2022Induced giant piezoelectricity in centrosymmetric oxides
Paul Muralt, Dragan Damjanovic, Vasiliki Tileli, Mahmoud Hadad, Lukas Riemer, Daesung Park
Piezoelectrics are materials that linearly deform in response to an applied electric field. As a fundamental prerequisite, piezoelectric materials must have a noncentrosymmetric crystal structure. For more than a century, this has remained a major obstacle ...
2022Crossover between distinct symmetries in solid solutions of rare earth nickelates
Duncan Thomas Lindsay Alexander, Bernat Mundet, Jean-Marc Triscone
A strong coupling of the lattice to functional properties is observed in many transition metal oxide systems, such as the ABO(3) perovskites. In the quest for tailor-made materials, it is essential to be able to control the structural properties of the com ...
AIP Publishing2021A stability theory beyond the co-rotational setting for critical wave maps blow up
We exhibit non-equivariant perturbations of the blowup solutions constructed in [18] for energy critical wave maps into . Our admissible class of perturbations is an open set in some sufficiently smooth topology and vanishes near the light co ...
2020Experimental studies of the equilibrium and out-of-equilibrium electronic structure of non-symmorphic topological materials
Symmetry and topology are fundamental properties of nature. Mathematics provides us with a general framework to understand these concepts. On one side, symmetry describes the invariance properties of an object for specific transformations. On the other sid ...
EPFL2020Robustness in Subwavelength Locally-Resonant Metamaterial Waveguides
Romain Christophe Rémy Fleury, Bakhtiyar Orazbayev, Nadège Sihame Kaïna
Guiding electromagnetic energy at a subwavelength scale is one of the most highly demanded functionalities in a variety of applications, including compact, lightweight satellite communications, signal and data processing, and power systems. The existing sc ...
IEEE Xplore2020Spherical Convolutionnal Neural Networks: Empirical Analysis of SCNNs
Convolutional neural networks (CNNs) are powerful tools in Deep Learning mainly due to their ability to exploit the translational symmetry present in images, as they are equivariant to translations. Other datasets present different types of symmetries (e.g ...
2019New refinement of the crystal structure of Zn(NH3)(2)Cl-2 at 100 K
The crystal structure of [ZnCl2(NH3)(2)], diamminedichloridozinc, was reinvestigated at low temperature, revealing the positions of the hydrogen atoms and thus a deeper insight into the hydrogen-bonding scheme in the crystal packing. In comparison with pre ...
