A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of ...
Scientists reveal hidden magnetic order in one-dimensional quantum crystals doped with holes
Magnetism is a phenomenon that we experience in everyday-life quite often. The property, which is observed in materials such as such as iron, is caused by the alignment of electron spins. Even more interesting effects are expected in case that the magnetic crystals exhibit holes, i.e., lattice ...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the ...
Physicists observe novel quantum effect that limits the number of emitted photons
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called Poisson-distribution. There are, however, light sources with non-classical photon number distributions that can only be described by the ...
One of the most promising materials for light-conversion technology
The anatase crystal form of Titanium dioxide (TiO₂) is one of the most promising materials for photovoltaic and photocatalytic applications nowadays. Despite years of studies on the conversion of light absorbed by anatase TiO₂, into electrical charges, the very nature of its fundamental ...
The quantum nature of light does usually not play an important role when considering the chemical properties of atoms or moelcules. In an article published in the Proceedings of the National Academy of Sciences scientists from the Max Planck Institute for the Structure and Dynamics of Matter ...
Visualizing the distribution of chemical substances on non-flat samples
The chemical analysis of biological tissues with three-dimensional shapes has been a major problem so far. Researchers at the Max Planck Institute for Chemical Ecology in Jena, Germany, have now improved mass spectrometry imaging in such a way that the distribution of molecules can also be ...
Scientists discover peculiarities in crystal structure of titanium alloy
Metals which can be bent as gum pave the way for new industrial applications for example in the aerospace industry. These so-called gum metals exist but the mechanism behind this behaviour was still unsettled and thus difficult to be used for applications. Scientists from the Max-Planck-Institut ...
First observation of Dirac fermions in graphene
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity to observe particle properties that have no realization in elementary particles. In the present study, an international research team led ...
Currently terrestrial ecosystems absorb about one quarter of the anthropogenic carbon dioxide emitted into the atmosphere. However, how this land carbon sink will develop in the future is uncertain and strongly depends on the responses of ecosystems to climate. New clues on how the land carbon ...
