Improving Sensitivity in Solid State NMR

Sensitivity in Nuclear Magnetic Resonance (NMR), especially in solid-state NMR, has always been a challenging and important issue and thus a motivation for new developments. The magnetic field B0, the gyromagnetic ratios of the observed nuclei, as well as ...

Effect of Uniaxial Compressive Stress on Dielectric and Piezoelectric Responses in Lead Zirconate Titanate Based Ceramics

Dragan Damjanovic

A uniaxial compressive stress significantly modifies the dielectric and piezoelectric response of Pb(Zr,Ti)O3 (PZT)-based piezoceramics. In soft PZT, the pre-stress decreases both the piezoelectric coefficient and its increment with increasing dynamical st ...

Cubic interactions and quantum criticality in dimerized antiferromagnets

Sandro Wenzel

In certain Mott-insulating dimerized antiferromagnets, triplet excitations of the paramagnetic phase display both three-particle and four-particle interactions. When such a magnet undergoes a quantum phase transition into a magnetically ordered state, the ...

Hamaker 2: A Toolkit for the Calculation of Particle Interactions and Suspension Stability and its Application to Mullite Synthesis by Colloidal Methods

Paul Bowen, Ulrich Aschauer

For modern processing of ceramics at the nanoscale, the influence of interparticle interactions in the suspended state becomes increasingly important. The Hamaker 2 program has been developed for the rapid prediction of these interactions, allowing us to g ...

A Density Dependent Dispersion Correction

Density functional approximations fail to provide an accurate treatment of weak interactions. More recent, but not readily available functionals can lead to significant improvements. A simple alternative to correct for the missing weak interactions is to a ...

Ruthenium(II) arene complexes with oligocationic triarylphosphine ligands: Synthesis, DNA interactions and in vitro properties

Paul Joseph Dyson, Angela Casini, Fabio Edafe, Dennis Snelders

The synthesis, DNA binding properties and cytotoxicity of a series of Ru(II)-arene complexes containing oligocationic ammonium-functionalized triarylphosphines, of the type Ru(p-cymene)Cl-2(L) (L - oligocationic phosphine), are reported. The complexes are ...

Refractive Index Gas Sensing in a Hollow Photonic Crystal Cavity

Romuald Houdré, Hua Zhang, Nicolas Le Thomas, Jana Jágerská, Zhaolu Diao

We investigate hollow photonic crystal structures consisting in air-slot photonic crystal nanocavities. The high quality factor similar to 2.6x10(4) of such cavities along with a strong overlap between the resonant mode and the hollow core region allows fo ...

Initial state radiation in Majorana Dark Matter annihilations

Andrea De Simone

The cross section for a Majorana Dark Matter particle annihilating into light fermions is helicity suppressed. We show that, if the Dark Matter is the neutral Majorana component of a multiplet which is charged under the electroweak interactions of the Stan ...

Ab initio theory of Fano resonances in plasmonic nanostructures and metamaterials

Olivier Martin, Benjamin Gallinet

An ab initio theory for Fano resonances in plasmonic nanostructures and metamaterials is de- veloped using Feshbach formalism. It reveals the role played by the electromagnetic modes and material losses in the system, and enables the engineering of Fano re ...

Full-field drift Hamiltonian particle orbits in 3D geometry

Jonathan Graves, Wilfred Anthony Cooper, Stephan Brunner

A Hamiltonian/Lagrangian theory to describe guiding centre orbit drift motion which is canonical in the Boozer coordinate frame has been extended to include full electromagnetic perturbed fields in anisotropic pressure 3D equilibria with nested magnetic fl ...
