Where? 306 aud. at Laser Research Center (Saulėtekio av. 10)

"Photonic quantum simulation: Limits and switching of topological protection and the influence of higher orbitals in coupled waveguide systems"

Abstract (find references here):

Applications of quantum technology are highly sought-after and thus supported by public funding agencies. However, the meaning of application varies depending on who you talk to: In the physics community application often means a useful laboratory implementation, while from an industrial perspective, application means solving a measurement problem in production or even creating a saleable product.

To address the physics perspective, I will discuss 3D µ-printed photonic quantum simulators based on coupled waveguide system, focusing on topological protection and Floquet (time-periodic) driving. Such experimental model systems allow for studying these phenomena under very well controlled conditions. Examples are periodic driving of topologically protected edge modes in the one-dimensional Su-Schrieffer-Heeger-chain leading to depopulation of the edge mode despite topological protection [1], periodic driving of two-dimensional honey-comb-lattices establishes topological protection in an otherwise topologically trivial model system [2], switching of topological protection via excitation with and without orbital angular momentum of light [3], and establishing higher-order topological insulators using p-orbitals of the waveguides [4].
From the industry perspective I will discuss recent results for a orbital-angular-momentum mode multiplexer/demultiplexer [5].

On 25 September at 15:00, in the Great Physics Auditorium (Faculty of Physics, VU, Saulėtekio av. 9), famous astronomer Vicent Martinez, professor at the University of Valencia and director of the Astronomical Observatory of the University of Valencia Prof. Vicent J. Martínez will give a public lecture "What Killed the Dinosaurs? And Other Science Stories You Were Wrongly Told".

On November 4 at 15:00, in A101 aud. (National Center for Physical and Technological Sciences, Saulėtekio ave. 3), Begoña Vila, Doctor of Astrophysics and NASA Instrument Systems Engineer, will give a public lecture "Two Wonderful Space Telescopes to Explore the Universe: James Webb and Nancy Grace Roman."

In her lecture, the scientist will discuss the projects she is contributing to—the James Webb Space Telescope and the Nancy Grace Roman Space Telescope—the challenges of working on missions of such scale and importance, their advanced technologies, and the opportunities they open up for science.

Dr Begoña Vila has been working on the James Webb Space Telescope since 2006 initially in Canada for the Fine Guidance Sensor & Near-Infrared Imager & Slitless Spectrograph (FGS/NIRISS) and since 2013 at NASA as Systems Lead for FGS/NIRISS and as Deputy for Operations of the JWST Science Instruments. She is also part of the Systems team on the Nancy Grace Roman Space Telescope and is the test director lead for its Thermal Vacuum test and co-lead on its Fine Guidance Sensor. She has received various achievement awards including the NASA Exceptional Public Achievement Medal in 2016, the NASA Exceptional Public Service Medal in 2022 and various awards in Spain.

On November 28 at 11:00, in the Main Hall of the Research Council of Lithuania (Gediminas ave. 3, Vilnius), Ana Ulla, Professor at the University of Vigo and Member of the Gaia Data Processing and Analysis Consortium (DPAC) Consortium Team, will give a public lecture "GAIA: A Wealth of Galactic Achievements".

Abstract

The ESA Gaia mission, launched in 2013 and operated until its passivation in 2025, has produced the most precise and extensive astrometric survey to date, delivering positions, parallaxes, proper motions, multi-band photometry and spectroscopy for almost two thousand million Galactic and extragalactic sources. With parallax precisions reaching a few tens of microarcseconds for bright stars and homogeneous BP/RP and RVS spectroscopic data, Gaia has transformed studies of stellar evolution, Galactic structure, star clusters, binary populations and the cosmic distance scale. Previous public data releases culminated in DR3 (2022), which provided enhanced astrophysical parameters, variability characterisation and large spectroscopic samples. The forthcoming DR4 (expected for 2026) and final all-mission DR5 (~2030) will refine astrometric accuracy, extend epoch photometry and spectroscopy, and deliver the definitive Gaia catalogue. Together, these releases ensure Gaia’s long-term legacy as a cornerstone dataset for modern astrophysics, Galactic archaeology and cosmology.

Prof. Dr Ana Ulla  holds a degree in Physical Sciences, specializing in Astrophysics. Her research lines include late stages of stellar evolution, exoplanets, astrobiology, and cultural astronomy, among others. She is a researcher in the GEOMA group at the Marine Research Center (CIM), and also collaborates with the Galician Group for the Gaia satellite (GGG) of ESA, preparing satellite data archives and supporting their scientific exploitation. 

Dr A. Ulla have been involved in the project since 2006. Now, with the end of Gaia’s scientific observations, Ulla’s data processing work has intensified – researchers are working hard on producing the 4th data catalogue, which will likely be released in 2026 and will include objects across all categories—from Solar System bodies to exoplanets and distant galaxies.

On 5–6 September, the message will be broadcast from the rooftop of the VU Faculty of Physics — we’re celebrating the Faculty’s 60th anniversary.

Join us on Friday and Saturday from 11:00. to 16:00, in the courtyard at Saulėtekio Ave. 9.

Discover the technology and equipment in use, refresh your Morse code skills, and explore a special installation prepared by the organisers of Physicist's Day (FiDi). And what about birthday gifts? We’ve got some waiting for you!

Faculty colleagues, alumni, members of the VU Radio Club, the Lithuanian Amateur Radio Society, FiDi, and other student organizations will seek to establish as many radio contacts as possible and will conduct special broadcasts.

This marks the beginning of a series of events celebrating the Faculty’s anniversary. We look forward to seeing you there.

Congratulations to everyone on the new school year!

Please note that Monday, 1 September is the opening day of Vilnius University's academic year, RENOVATIO STUDIORUM – thus there will be no lectures on that day. Everyone is welcome to take part in the celebration events.

Students of the Faculty of Physics:

  • Undergraduates, we are waiting for you at 11.00 at the Faculty of Physics of Vilnius University, in the Great Physics Auditorium (Saulėtekis av. 9, Building III, 1st floor)
  • Master's students, we are waiting for you at 12.00 at the Faculty of Physics, in the Great Physics Auditorium (Saulėtekis av. 9, Building III, 1st floor)

RENOVATIO STUDIORUM events will also take place at VU faculties, where students from Lithuania and abroad will meet their faculty's academic community and future study mates. At a ceremony in the VU Grand Courtyard (in the Oldtown), first-year students will take the oath of allegiance to their university, and the community will be greeted by university and city leaders. Students, faculty, administrative staff, city residents and guests are invited to celebrate the start of the academic year. The programme.

Please also note that 1-5 September is the integration week for undergraduate freshmen and there will be no lectures for them.

For all other courses, lectures will start on 3 September (Tuesday).

Lecture timetables are available here.
