Magnetic Excitations and Electronic Interactions in Sr2CuTeO6: A Spin-1/2 Square Lattice Heisenberg Antiferromagnet

Henrik Moodysson Rønnow, Oleg Yazyev, Peter Babkevich, Vamshi Mohan Katukuri

Sr2CuTeO6 presents an opportunity for exploring low-dimensional magnetism on a square lattice of S = 1/2 Cu2+ ions. We employ ab initio multireference configuration interaction calculations to unravel the Cu2+ electronic structure and to evaluate exchange ...

Spin and Charge transport in Dirac Materials

Alexander Ronald Hoyer

The digitalization of our world is proceeding with every new technical product placed on the market. By making them smarter, e.g. linking them together and equipping them with sensors, a vast mass of data is collected. Processing and storing this informati ...

Dramatic pressure-driven enhancement of bulk skyrmion stability

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Helmuth Berger, Jonathan White

The recent discovery of magnetic skyrmion lattices initiated a surge of interest in the scientific community. Several novel phenomena have been shown to emerge from the interaction of conducting electrons with the skyrmion lattice, such as a topological Ha ...

Acoustic topological insulators

Romain Christophe Rémy Fleury

The recent discovery of topological states in condensed matter physics has spawned a quest for similar effects in classical physics. Topological insulators are bulk insulators supporting bandgap crossing, chiral edge states that are immune to backscatterin ...

Nuclear Quantum Effects in Water and Aqueous Systems: Experiment, Theory, and Current Challenges

Michele Ceriotti, Wei Fang

Nuclear quantum effects influence the structure and dynamics of hydrogen-bonded systems, such as water, which impacts their observed properties with widely varying magnitudes. This review highlights the recent significant developments in the experiment, th ...

Backward diodes using heavily Mg-doped GaN growth by ammonia molecular-beam epitaxy

Nicolas Grandjean, Marco Malinverni, Denis Martin, Hironori Okumura

We grew heavily Mg-doped GaN using ammonia molecular-beam epitaxy. The use of low growth temperature (740 degrees C) allows decreasing the incorporation of donor-like defects (

Dinuclear clathrochelate complexes with pendent cyano groups as metalloligands

Rosario Scopelliti, Kay Severin, Henrik Moodysson Rønnow, Ivica Zivkovic, Philip Pattison, Bálint Náfrádi, Euro Solari, Giacomo Cecot, Mathieu Jérémie Marmier, José Luis Bila

Dinuclear clathrochelate complexes with two, three, four, or five cyano groups in the ligand periphery were prepared following two distinct synthetic strategies: (a) zinc(II)- or cobalt(II)-templated polycondensation reactions of CN-functionalized arylboro ...

Observation of quantized conductance in neutral matter

Jean-Philippe Brantut

In transport experiments, the quantum nature of matter becomes directly evident when changes in conductance occur only in discrete steps1, with a size determined solely by Planck's constant h. Observations of quantized steps in electrical conductance2,3 ha ...

Electrochemical nanostructured biosensors: carbon nanotubes versus conductive and semi-conductive nanoparticles

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Gianluca Piccinini

The aim of this work was to demonstrate that various types of nanostructures provide different gains in terms of sensitivity or detection limit albeit providing the same gain in terms of increased area. Commercial screen printed electrodes (SPEs) were func ...

Mapping out spin and particle conductances in a quantum point contact

Jean-Philippe Brantut

We study particle and spin transport in a single mode quantum point contact using a charge neutral, quantum degenerate Fermi gas with tunable, attractive interactions. This yields the spin and particle conductance of the point contact as a function of chem ...
