Refined swampland distance conjecture and exotic hybrid Calabi-Yaus
Journal of High Energy Physics, 2019 We test the refined swampland distance conjecture in the Kähler moduli space of exotic one-parameter Calabi-Yaus. We focus on examples with pseudo-hybrid points. These points, whose properties are not well-understood, are at finite distance in the moduli

Advanced Functional Materials, EarlyView.We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers
Advanced Functional Materials, EarlyView.We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Advanced Functional Materials, EarlyView.A thermodynamic model that incorporates ferroelectric, antiferroelectric, and antiferrodistortive orders of PbZrO3${\rm PbZrO}_3$ is established and parameterized based on experimental measurements and first‐principles calculations. We derive a Clapeyron‐like equation for describing the temperature‐dependence of critical electric fields for the ...

Pseudo-coordinations in Faroese [PDF]
, 2012 In this article we describe the system of pseudo-coordinations in Faroese—coordinations in the verbal system in which the second conjunct appears in fact to be subordinated to the first—in the light of previous discussions of this phenomenon in ...

Journal of Mathematical Analysis and Applications, 2013 Abstract We consider the one-parameter families of Gauss indicatrices on Lorentzian hypersurfaces in pseudo-spheres in semi-Euclidean 4-space with index 2 and give the types of singularities of the Lorentzian hypersurfaces by the contact theory.

Electrostatic Superlattices Beyond 1:1 Stoichiometry
Advanced Functional Materials, EarlyView.Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Communications, Faculty Of Science, University of Ankara Series A1Mathematics and Statistics, 1994 The paper under review is divided into two main sections. In the first one, the authors study isometric immersions of Lorentzian submanifolds with planar normal sections in the Lorentz-Minkowski space. In particular, they obtain similar characterizations to those of submanifolds with planar normal sections in the Euclidean space given in [\textit{B.-Y.
