EPJ ST Highlight - Exploring strangeness and the primordial Universe

Having studied quark-gluon plasma since the late 1970s, Dr Johann Rafelski summarises the evolution in our understanding of the exotic quark signature of this primordial material which once filled the whole Universe.

Physicists believe that in the Universe’s first ten microseconds free quarks and gluons filled all of spacetime, forming a new phase of matter named ‘quark-gluon plasma’ (QGP). Experimental and theoretical work at CERN was instrumental in the discovery of this hot soup of primordial matter, which is recreated today in accelerator-based lab experiments. To discover QGP in such experiments, the observation of exotic ‘strange’ quarks is very important. If QGP is created, strangeness is readily produced through collisions between gluons. In analysis published in EPJ Special Topics, Dr Johann Rafelski from The University of Arizona, United States, also working at CERN, presents how our understanding of this characteristic strangeness production signature has evolved over the span of his long career.


Erik Akkermans joins the EPJ Scientific Advisory Committee (SAC)

Eric Akkermans

The SAC is very pleased to welcome Eric Akkermans as a new representative of the Israel Physical Society. Eric Akkermans is a professor at the physics department at Technion. He is working on condensed matter physics and more particularly on subjects that sit at the crossroad between quantum physics, equilibrium and out of equilibrium physics, quantum field theory, cold atomic gases and mesoscopic physics. The theoretical activity of the research group of E. Akkermans is systematically related to experimental works either triggering new experiments or trying to explain existing results.

EPJ Plus Focus Point: Scientific Research in Conservation Science

This special issue is related to the 3rd edition of the International Conference on Innovation in Art Research and Technology (inArt 2018) held in Parma (Italy). The Focus Point includes 20 excellent examples of the research works presented at the Conference. In particular, attention is focused on: non-invasive investigation techniques; new materials for restoration in compliance with the artifacts and the environment; products for the prevention of corrosion and of degradation; self-cleaning materials. The articles are devoted to the study of many different art objects and materials, including paintings (pigments, dyes, binders), textiles, manuscripts, buildings as well as building materials, metals, glasses, gems, bones and ivory. The analyzed objects span a huge time interval, ranging from antiquity (ancient Egypt) to contemporary art. Many different techniques are involved: spectroscopy in the different ranges of the electromagnetic spectrum (from infrared to X-rays); visible and electron microscopy; multispectral imaging; three-dimensional reconstruction, using instruments as handheld spectrometers, neutron sources or particle accelerators. Data treatment is also discussed, from databases to data integration and decision tools.


This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
