Spin polarization detection via chirality-induced tunnelling currents in indium selenide

Shun Feng, Andras Kis, Gabriele Pasquale, Eloi Régis L Collette

Chirality, a basic property of symmetry breaking, is crucial for fields such as biology and physics. Recent advances in the study of chiral systems have stimulated interest in the discovery of symmetry-breaking states that enable exotic phenomena such as s ...

Multimodal Approach Reveals the Symmetry-Breaking Pathway to the Broken Helix in EuIn2As2

Jian Rui Soh

Understanding and manipulating emergent phases, which are themes at the forefront of quantummaterials research, rely on identifying their underlying symmetries. This general principle has been particularly prominent in materials with coupled electronic and ...

Randomized methods for computing joint eigenvalues, with applications to multiparameter eigenvalue problems and root finding

Daniel Kressner, Haoze He

It is well known that a family of n×n commuting matrices can be simultaneously triangularized by a unitary similarity transformation. The diagonal entries of the triangular matrices define the n joint eigenvalues of the family. In this work, we consider th ...

Structure, reactivity and luminescence studies of triphenylsiloxide complexes of tetravalent lanthanides

Jean-Claude Bünzli, Marinella Mazzanti, Farzaneh Fadaei Tirani, Anne-Sophie Chauvin, Aurélien René Willauer

Among the 14 lanthanide elements (Ce-Lu), until recently, the tetravalent oxidation state was readily accessible in solution only for cerium while Pr(iv), Nd(iv), Dy(iv) and Tb(iv) had only been detected in the solid state. The triphenylsiloxide ligand rec ...

Directional ballistic transport in the two-dimensional metal PdCoO2

Matthias Carsten Putzke

In an idealized infinite crystal, the material properties are constrained by the symmetries of the unit cell. The point-group symmetry is broken by the sample shape of any finite crystal, but this is commonly unobservable in macroscopic metals. To sense th ...

Low-scale leptogenesis with flavour and CP symmetries

Marco Drewes, Juraj Klaric

We consider a type-I seesaw framework endowed with a flavour symmetry, belonging to the series of non-abelian groups increment (3 n(2)) and increment (6 n(2)), and a CP symmetry. Breaking these symmetries in a non-trivial way results in the right-handed ne ...

Charge transfer enhanced magnetic correlations in type-II multiferroic Co3TeO6

Helmuth Berger

Magnetic structure of the Co ions in monoclinic Co3TeO6 in the antiferroelectric state at 16 K has been determined by neutron powder together with single-crystal diffractions. The indices of the magnetic reflections that appear at the incommensurate positi ...

Complements to Mugge and Friedel's Theory of Twinning

Cyril Cayron

The crystallography of twinning is based on the concepts of simple shear and obliquity introduced by Mugge, Mallard and Friedel at the turn of the last century, with tensor mathematics later developed by Bilby, Bevis and Crocker in the 1960s. We propose a ...

Promising anti-cancer potency of 4,5,6,7-tetrahydrobenzo[d]thiazole-based Schiff-bases

Kurt Schenk, Farzaneh Fadaei Tirani

Four new Schiff-bases have been synthesized from the 1:2 M condensation of 4,5,6,7-tetrahydrobenzothiazole-2,6-diamine with 2-hydroxybenzaldehyde (SL3), 5-Bromo-2-hydroxybenzaldehyde (SL2), 2-hydroxy-3-methoxybenzaldehyde (SL3) and 2-hydroxy-1-naphthaldehy ...

Guest-dependent negative thermal expansion in a lanthanide-based metal-organic framework

Berend Smit, Kyriakos Stylianou, Seyedmohamad Moosavi, Andrzej Gladysiak

A lanthanide-based metal-organic framework (MOF) named SION-2 displays strong and tuneable uniaxial negative thermal expansion (NTE). The coefficient of thermal expansion alpha(1) reaches -153(6) MK-1 between 100 and 340 K, which is the highest value repor ...

Symmetries and Angular Scattering Properties of Metasurfaces

Olivier Martin, Karim Achouri

We study the angular scattering behavior of bianisotropic metasurfaces and deduce relationships between the corresponding symmetrical angular scattering properties and the structural symmetries of their scattering particles. This may be of practical intere ...

Small molecule activation by multimetallic uranium complexes supported by siloxide ligands

Marinella Mazzanti, Luciano Barluzzi, Marta Falcone

The synthesis and reactivity of uranium compounds supported by the tris-tert-butoxysiloxide ligand is surveyed. The multiple binding modes of the tert-butoxysiloxide ligand have proven very well suited to stabilize highly reactive homo- and heteropolymetal ...

Group Actions On Dendrites And Curves

Nicolas Monod

We establish obstructions for groups to act by homeomorphisms on dendrites. For instance, lattices in higher rank simple Lie groups will always fix a point or a pair. The same holds for irreducible lattices in products of connected groups. Further results ...

Momentum-space conformal blocks on the light cone

We study the momentum-space 4-point correlation function of identical scalar operators in conformal field theory. Working specifically with null momenta, we show that its imaginary part admits an expansion in conformal blocks. The blocks are polynomials in ...
