Preface

The fourth International Physics Conference in Bosnia and Herzegovina (PHYCONBA2024) was held on 26-27 September 2024 at the premises of the Faculty of Science in Sarajevo. The conference is a biennial scientific meeting organised by the Physical Society in Federation of Bosnia and Herzegovina with the support of the Faculty of Science, University of Sarajevo. The inaugural International Physics Conference in Bosnia and Herzegovina was held in October 2018, with a considerable number of participants in attendance. In 2020, the event was held in a reduced hybrid format due to the global pandemic caused by the SARS-CoV-2 virus. In 2022, the number of participants returned to the level observed prior to the pandemic. The principal objective of the event is to facilitate interaction and collaboration among physicists from Bosnia and Herzegovina, neighbouring countries, and the scientific diaspora. This will be achieved through the exchange of information, the presentation of recent research findings, and the establishment of collaborative relationships. The conference will address all areas of research within the field of physics, as well as related subjects. The two-day programme comprises three plenary talks, 9 oral presentations and 19 poster presentations. On the second day of the programme, a presentation was given on the major modernisation project that took place between 2020 and 2022 at the Department of Physics. Furthermore, attendees were afforded the chance to view the recently refurbished laboratories. On the second day of the event, a half-day excursion to the nearby Trebević mountain was offered as an official part of the programme. This enabled participants to enjoy local attractions and participate in informal discussions in a relaxed atmosphere. It is the sincere hope of the Organising Committee that the participants derived considerable benefit from their stay in Sarajevo and that this event will prove to be an effective forum for the exchange of ideas and the establishment of new collaborations. In my capacity as Guest Editor of this special issue, I would like to extend my gratitude to all those who participated in the Fourth International Physics Conference in Bosnia and Herzegovina. I would also like to acknowledge the contributions of the Organising and Scientific Committee, as well as the student volunteers, whose efforts were instrumental in the successful organisation of this event. Finally, I would like to recognise the possibility of partial financial support from the Federal Ministry of Education and Science, Bosnia and Herzegovina. However, the outcome of the funding application remains to be announced. List of Organising committee, Scientific committee and Participants are available in this Pdf.
