‘Physics is an old science, there’s so much to do here. The most difficult part is choosing exactly what,’ jokes Vilnius University (VU) scientist Prof Gediminas Gaigalas. His theories and atomic calculation programs are essentially unrivalled. Very often, complex physics projects are simply impossible without his contributions. The latest example is an international study that has finally explained an anomaly that has troubled scientists for many years.

On 26–27 June, during a visit to Vilnius University (VU) by a delegation from France’s Sorbonne University, its President, Prof. Nathalie Drach-Temam, was presented with a printed replica of the Sorbonne University Chapel, which appears as a mere dust particle to the naked eye. The special gift was created by Dr Gordon Zyla, a senior researcher at the Laser Research Center of the VU Faculty of Physics and a former Marie Skłodowska-Curie Postdoctoral Fellow.

This seminar will present how cold atoms and topological phenomena are merging into one of the most exciting research areas in modern physics. Using cold atoms in optical lattices, scientists can simulate topological phases in materials - from topological insulators and superconductors to the Quantum Hall effect. Such models allow the study of edge states, quantum responses and new quantum phases of matter that do not exist in ordinary materials.

Scientists from Vilnius University (VU) Faculty of Physics, together with colleagues from Poland and other countries, have identified an exoplanet – a gas giant located far from the Galactic Centre. This is only the third such discovery in the entire history of observations. The discovery is even more exceptional due to the method used – the phenomenon known as microlensing. The results of the observations have been published in one of the most prestigious astronomy journals “Astronomy & Astrophysics”.

The graduation season is just around the corner, when St Johns’ Church and other venues chosen for the official diploma-awarding ceremonies will be filled with the joyful bustle of graduates. As we approach this celebration, please be reminded that you are welcome to wear a VU cap during the ceremony.

Dr Mindaugas Šarpis, a researcher at the Institute of Photonics and Nanotechnology, Faculty of Physics, Vilnius University (VU), and leader of the LHCb Vilnius group, has been awarded a prestigious ERA Fellowship grant under Horizon Europe funding programme for his postdoctoral research. The funding, amounting to almost 200,000 Eur will strengthen Lithuania’s competences in particle physics and lay the foundations for further research at VU.

Arqus is glad to launch a joint call for Blended Intensive Programmes (BIP) and a call for Arqus Twinning 2.0 projects. These two calls are aimed at academic staff to reinforce the collaboration between the members of the Alliance and to propose short-term mobility opportunities for students and staff.

Lithuania stands out globally for its rapidly developing light technology industry, with lasers playing a key role in this important ecosystem. The laser infrastructure at Vilnius University’s (VU) Faculty of Physics is equally renowned for its international outlook and open science practices. Long-standing collaboration between the academic community and industry here drives innovative solutions.

Hong-Ou-Mandel effect (HOM), also known as two-photon interference, is a key tool in quantum optics laboratories, and has powerful applications for metrology and sensing even in the classical regime. We recently demonstrated that HOM interferometry can be used to for fluorescence lifetime imaging – a key tool in biomedical research that can detect changes in cell microenvironment such as temperature, pH, viscosity and protein-protein interactions. 

For her contributions to astrophysical science and the development of astrospectroscopy, initiation of exoplanet research in Lithuania, dissemination of knowledge on the understanding of the Universe, and for promoting the name of Lithuania in the world, she was awarded with the Ignotas Domeika Medal and became an honorary member of the Lithuanian Ignotas Domeika Society.
