Scale-invariant magnetic anisotropy in RuCl(3)at high magnetic fields

Philip Johannes Walter Moll, Maja Deborah Bachmann

Scale-invariant magnetic anisotropy in RuCl(3)has been revealed through measurements of its magnetotropic coefficient, providing evidence for a high degree of exchange frustration that favours the formation of a spin liquid state. In RuCl3, inelastic neutr ...

Resonant torsion magnetometry in anisotropic quantum materials

Philip Johannes Walter Moll, Maja Deborah Bachmann, Kent Robert Shirer, Amelia Emily-Kay Estry

Unusual behavior in quantum materials commonly arises from their effective low-dimensional physics, reflecting the underlying anisotropy in the spin and charge degrees of freedom. Here we introduce the magnetotropic coefficient k = partial derivative F-2/p ...

New method for measuring compressibility and poroelasticity coefficients in porous and permeable rocks

Lucas Xan Pimienta

Over the last decades, a large understanding has been gained on the elastic properties of rocks. Rocks are, however, porous materials, which properties depend on both response of the bulk material and of the pores. Because in that case both the applied ext ...

Coexistence of localized and collective magnetism in the coupled-spin-tetrahedra system Cu4Te5O12C14

Helmuth Berger

We report high-field magnetization, electron spin resonance (ESR), and Raman scattering measurements of the coupled spin-tetrahedra system Cu4Te5O12C14 with magnetic ordering at T-N = 13.6 K. We find thermodynamic and spectroscopic signatures for the conco ...

First-Principles Prediction of the Equilibrium Shape of Nanoparticles Under Realistic Electrochemical Conditions

Nicola Marzari, Nicéphore Arthur François Bonnet

A first-principles model of the electrochemical double layer is applied to study surface energies and surface coverage under realistic electrochemical conditions and to determine the equilibrium shape of metal nanoparticles as a function of applied potenti ...

On the non-analytic behaviour of thermodynamic potentials at first order phase transitions

Sacha Friedli

This work is devoted to the study of the analyticity properties of thermodynamic potentials (free energy, pressure) for classical lattice systems at low temperature. The central topic of our analysis, in this framework, is to show rigorously the absence of ...

Evidence for strong correlations in a 1D Peierls system

Marco Grioni, Helmuth Berger, Luca Perfetti

New temperature-dependent angle resolved photoemission (ARPES) data on the quasi-one-dimensional Peierls compound (TaSe4)(2)I suggest a new interpretation of the spectral lineshapes, which removes discrepancies with the transport and thermodynamic results. ...

H-aggregation and correlated absorption and emission of a merocyanine dye in solution, at the surface and in the solid state. A link between crystal structure and photophysical properties

Michael Graetzel

The formation of H-aggregates as a function of solution, substrate and ambient variables is considered for the merocyanine dye 3-acetyl-5-12-(3-ethyl-2-benzothiazolydene) rhodanine. Colloidal semiconductor particles are shown to be a powerful tool to contr ...
