The apparent inner calm of quantum materials

The apparent inner calm of quantum materials

Transitions between different phases of matter are part of our day-to-day lives: when water freezes, for example, it passes from liquid to solid state. Some of these transitions may be of a different kind, resulting from so-called topological excitations that force all the particles to act in unison. Researchers from the University of Geneva (UNIGE)…

When superconductivity disappears in the core of a quantum tube

When superconductivity disappears in the core of a quantum tube

Predicting the behaviour of electrons in a material is not easily done. Physicists from the University of Geneva (UNIGE), ETH Zurich and EPFL replaced the electrons with ultra-cold neutral lithium atoms that they had circulated in a one-dimensional quantum tube. The scientists were then able to confirm an unusual state of matter that retains its…

The complex effect of strain on the structure of perovskite vanadates

The complex effect of strain on the structure of perovskite vanadates

Scilight from AIP Publishing is talking about a recent publication of Hugo Meley and coworkers in APL Materials. Moving from discovering physical properties to the ability to tailor them requires precise understanding and mastery of materials fabrication. This study unveils how the substrate affects the growth of crystalline vanadate thin films and the arrangement of their…

Ultra-subwavelength nano-optical microscopy at cryogenic temperatures at the DQMP

Ultra-subwavelength nano-optical microscopy at cryogenic temperatures at the DQMP

A unique cryogenic scanning near-field optical microscope (cryo-SNOM) has been installed at the DQMP and is now able to demonstrate the first promising results. In contrast to the conventional optical microscopes, in this system the sample is probed by the so called evanescent electromagnetic waves, which are emitted and detected by an ultrasharp metallized tip…

Talk with Marta Gibert, MaNEP Board, SNSF Professor at UniZH

What have been the highlights of your research during these last years? My research has always been in the field of oxides materials; I am interested in oxide interface physics and in the engineering of high quality artificial functional heterostructures. In the last years, my work has mainly focused on the study of the perovskite…

A BCS fingerprint revealed by the vortices of a high Tc superconductor

A BCS fingerprint revealed by the vortices of a high Tc superconductor

by Christophe Berthod, Ivan Maggio-Aprile, Christoph Renner, Department of Quantum Matter Physics, University of Geneva based on an article published in Physical Review Letters Copper oxide superconductors were the first to be found superconducting above liquid nitrogen temperature in the mid-1980s, thus shattering through the maximum critical temperature of 35K foreseen by theorists. The mechanism enabling…

Spin Resonance in an Unconventional Superconductor

Spin Resonance in an Unconventional Superconductor

by Daniel Mazzone, Paul Scherrer Institut based on an article published in Physical Review Letters Most superconducting condensates are accurately described within the scope of the BCS-theory (Bardeen-Cooper-Schrieffer), where electrons are bound together via virtual phonons. They are in strong contrast to so-called unconventional superconductors, in which the pairing mechanism is still unclear but thought to arise from magnetic…

Advances in the study of the properties of superconducting materials

Advances in the study of the properties of superconducting materials

In a superconductor, the electrons experience very peculiar interactions whose most surprising effect is a total loss of electrical resistance. These materials are therefore promising for future applications, especially since some of them work at the temperature of liquid nitrogen. The mechanism behind these exceptional properties remains mysterious, though. Studying these materials when they are…
