Meet Us at the 4th International Conference on Symmetry (Symmetry 2023), 21–23 June 2023, Barcelona, Spain


We are delighted to announce that the 4th International Conference on Symmetry (Symmetry 2023) will be back in person in 2023. The event is supported by MDPI’s open access journal Symmetry (ISSN: 2073-8994) and will be held from 21 to 23 June 2023 in Barcelona, Spain.

As expressed by Hermann Weyl, who was responsible for important progress in the field of symmetry in math and physics: “Symmetry is a fundamental phenomenon in nature and all sciences”. Additionally, to quote Frank Wilczek, “powerful symmetry principles have guided physicists in their quest for nature's fundamental laws”. Although one should add, at the same time, that many of the most interesting situations happen to occur when some fundamental symmetry principle is broken. It thus seems as if nature abhors perfect symmetry.

It is this interplay between symmetry and its breakdown, in the many different domains and situations where they appear, which we want to address at the 4th Symmetry Conference in Barcelona. Specifically, we will foster interaction between scholars working in different fields of science.

We welcome scholars, engineers, students, and non-academic colleagues to join Symmetry 2023, and we kindly ask you to save the date. We aim to make this event a forum for discussion, knowledge exchange, and fruitful interactions among stakeholders working in various symmetry-related fields, such as computer science, mathematics, physics, chemistry, biology, and engineering science. Both oral and poster contributions are welcome.

We are pleased to announce the availability of awards for postdocs, Ph.D. students, and researchers conducting research in the field of symmetry and who plan to attend Symmetry 2023.

Best Oral Presentation (award: EUR 500)

Selected by the Scientific Committee after evaluation of all selected talks presented during the conference.

Best Poster (award: EUR 300)

We are very enthusiastic about this 4th Symmetry Conference; we hope that together we can help make it a successful event.

We look forward to meeting you in Barcelona.

Symmetry Webinar | The Dark Universe: The Harbinger of a Major Discovery, 25 May 2023


Welcome message by Prof. Dr. Konstantin Zioutas, Webinar Chair:

Physics is full of unanswered questions. In space science, we are faced with a large number of observations of unknown origin, even within our solar system. We recall, as an example, the historic observation in the 1930s by Fritz Zwicky of some suspected matter in the universe, which he called “dunkle Materie”, also known as dark matter. Dark matter (DM) dominates the universe, with its mass being about five times that of the normal matter we, the planets, the stars, etc., are made of. After 90 years, we can only suspect the microscopic constituents of DM, and assume that it interacts gravitationally. Thus, we live inside a well-hidden, dark universe. Undoubtedly, it is of utmost importance to identify the nature of DM. Therefore, it is safe to predict that the expected discoveries at present will overshadow historical discoveries. This is a challenge but also a unique opportunity for people fascinated by the unknown. The study of DM is exciting and highly motivating. In particular, for young people faced with the decision of choosing an exciting and rewarding career, astroparticle physics might just be the choice. Delving deeper into this exploration of DM, we pose some questions that we excitedly await the answers to:

What is dark matter? What is dark energy? Why is there an arrow of time? Are there parallel universes? Why is there more matter than antimatter? What is the fate of the universe? Is string theory correct? Do the universe's forces merge into one? What happens inside a black hole? What lies beyond the Standard Model? Fundamental constants? Do living things sense the dark universe?  

In this webinar, we will hear from two experienced physicists (Prof. Dr. Ariel Zhitnitsky, Canada, and Prof. Michael Tobar, Australia), as well as two physicists who are just beginning their promising careers in this area (Prof. Dr. Abaz Kryemadhi, USA, and Dr. Javier Miguel, Spain).

All four speakers work at the forefront of physics research, and therefore they will provide an appropriate introduction to this topic.

Date: 25 May 2023 at 4:00 p.m. CEST | 10:00 a.m. EDT | 10:00 p.m. CST Asia
