Phonon nanoengineering: Vibrations of nanoislands dissipate heat more effectively

8 March 2017

Europium silicide has for some time attracted the attention of scientists. Recognized as being promising for electronics and spintronics, this material has recently been submitted by a team of physicists from Poland, Germany and France to comprehensive studies of the vibrations of its crystal lattice. The results yielded a surprise: deposited on a substrate of silicon, some structures of europium silicide appear to vibrate in a way that clearly broadens the possibilities of designing nanomaterials with tailored thermal properties.

Inverted, but not perfectly: First trace of differences between matter and 'ordinary' antimatter

22 February 2017

The world around us is mainly constructed of baryons, particles composed of three quarks. Why are there no antibaryons, since just after the Big Bang, matter and antimatter came into being in exactly the same amounts? A lot points to the fact that after many decades of research, physicists are closer to the answer to this question. In the Large Hadron Collider beauty (LHCb) experiment the first trace of the differences between baryons and antibaryons has just been encountered.

Nuclear Surfing: Protons have been observed 'catching a wave' on the surface of an atomic nucleus

14 December 2016

For surfers, it's not enough just to wait for the right wave: they still have to know how to catch it. As it turns out, one challenge faced by surfers also applies to protons. An experiment recently conducted by physicists from Poland, Italy and France provided new information on surfing taken to its absolute extreme: protons synchronizing their movement with the vibrations of atomic nuclei.

Overlooked elements of language and literature play a key role

30 November 2016

Everything is pointing towards success in unravelling the mysteries inherent in every human language, which for nearly 100 years have been an object of intrigue for mathematicians and linguists working on studies into statistics of literature. New analysis of the frequencies of word occurrence in the most famous works of literature, undertaken at the Institute of Nuclear Physics of the Polish Academy of Sciences in Kraków, have shown that our languages are structurally more complex and more exhaustive than they ever before seemed.

Finding the lightest superdeformed triaxial atomic nucleus

19 October 2016

The nuclei of atoms of heavy elements do not necessarily take a spherical shape: they may be variously extended or flattened along one, two or even three axes. An international team of physicists, led by scientists from the Institute of Nuclear Physics of the Polish Academy of Sciences in Krakow (IFJ PAN) and the Heavy Ion Laboratory at the University of Warsaw (HIL), has recently presented the results of experiments showing that complex superdeformed nuclei occur in much lighter elements as well.

At the LHC, charmed twins will soon be more common than singles

8 June 2016

In the range of energies penetrated by the LHC accelerator, a new mechanism of the creation of particles is becoming more prominent, say scientists from the Institute of Nuclear Physics of the Polish Academy of Sciences in Krakow. The comparison between theoretical predictions and test data leaves no doubt: the energy in collisions is now so great that some of the elementary particles, mesons containing charm quarks, are beginning to emerge in pairs as often as single ones - and even more often.
