Excitons are pairs of electrons and holes inside a solid material that together behave like a single particle. It has long been suspected that when many such excitons exist in the same piece of matter, they can form a Bose-Einstein condensate. However, actually proving that Bose-Einstein condensation of excitons occurs in any real material has been a challenge for physicists for decades. Experimental evidence of such a state has been found!
A comment about the discovery: Spontaneous Bose-Einstein condensation of excitons

Part of the broad mission of a scientist is to talk about science! There are a number of different occasions, conferences, festival, university open days and fairs, and the audiences can vary a lot ranging from people who work in your area of interest or in related fields, to potential funders, from high-school students, to general public.
Unfortunately, instead of engaging audiences and conveying enthusiasm, many presentations fall often flat. Pitfalls include overly complicated content, monotone delivery and focusing on what you want to say rather than what the audience is interested in hearing.
Creating a dynamic, engaging and effective presentation is a difficult task! In what follows some material I found online that can be useful to improve the effectiveness of our public speeches:
- There are two major facets to a presentation: the content and how you present it. Let’s face it, no matter how great the content, no one will get it if they stop paying attention. Here are some pointers on how to create clear, concise content and how to give a dynamic scientific presentation.
- Your presentations need great visuals to succeed. Skeptical? Check out these impressive statistics on the power of visuals.
- The concept of “Death by PowerPoint” has largely been blamed on the over use of bullets in presentations. How can you avoid people dying of your bullets? These are 10 techniques to use on your slides if you are stuck with the bullets and minimize the chance your audience will fall asleep during your presentation…
Trieste was selected to host the EuroScience Open Forum, the most important European event dedicated to science, technology, society and policy. The event will take place from 4 to 10 July 2020. TRIESTE ESOF 2020
The old harbor area of Trieste
The International School for Advanced Studies in Trieste offers 2 fellowships in the framework of an “Advanced Training Programme” leading to a fast track PhD in connection with the Inter-University Master course in Physics jointly delivered by the Universities of Trieste and Udine.
The programme lasts 2 years, it is aimed to candidates who wish to acquire theoretical tools and necessary skills to start a high level research activity in Theoretical Physics of the Condensed Matter and it consists of two parallel and complementary trainings: the Inter-University Master course in Physics jointly delivered by the Universities of Trieste and Udine and a set of courses held by the researchers and professors of the SISSA “Theory and Numerical Simulations of Condensed Matter” PhD course.

A postdoctoral position is available at the Condensed matter group of SISSA/ISAS (International School of Advanced Studies), in the group of of Massimo Capone, starting in Summer/Fall 2017.
The research activity is focused on strongly correlated materials close to Mott transitions using many-body approaches like Dynamical Mean-Field Theory, Gutzwiller approximation and slave-particle approaches in combination with Density-Functional Theory.
These approaches will be applied to explore the properties of iron-based superconductors, iridates and transition-metal oxides, but also fullerides and other organic materials, exploring the relation between many-body physics and functional properties of the materials. We will also explore non-equilibrium dynamics of these systems in close collaboration with experimental groups.
An experience in the above mentioned approaches is highly desirable. Candidates with some experience in the combined use of DFT and many-body approaches are ideal for the position.
The position is for two years with a possible one-year renewal.
Interested applicants should send a CV, list of publications, research interests, and the names of two references to firstname.lastname@example.org.
Let conclude our 2016 with 10 amazing stories of science selected by David Grimm, online editor of Science: Top 10 fovorite science news stories of 2016
“This year’s Laureates opened the door on an unknown world where matter exists in strange states. The Nobel Prize in Physics 2016 is awarded with one half to David J. Thouless, University of Washington, Seattle, and the other half to F. Duncan M. Haldane, Princeton University, and J. Michael Kosterlitz, Brown University, Providence. Their discoveries have brought about breakthroughs in the theoretical understanding of matter’s mysteries and created new perspectives on the development of innovative materials.
The three Laureates’ use of topological concepts in physics was decisive for their discoveries. Topology is a branch of mathematics that describes properties that only change step-wise. Using topology as a tool, they were able to astound the experts. ”
