In this seminar, we will discuss the harmonic oscillator as a bridge between classical and quantum mechanics. After reviewing these (mostly familiar) concepts, we will move on to an analogous connection between the classical harmonic oscillator and classical field theory.

The lecture will take place on April 20 at Saulėtekio av. 3, in English. Registration and more information: https://openreadings.eu/special-event-2026/
On February 19 at 15:00 at VU Library’s Scholarly Communication and Information Centre (MKIC), Saulėtekio ave. 5, Orlando Naranjo, a distinguished astronomer, will give a public lecture "Frontiers of Deep Space: From Near-Earth Asteroids to Interstellar Voyagers".
The emerging field of Quantum Machine Learning (QML) lies at the intersection of quantum computing and advanced data analysis, offering the potential to fundamentally transform the way complex computational problems are addressed. During the presentation, attendees will be introduced to the core principles of quantum computing, including qubits and the structure of quantum circuits.
In recent years, Rydberg atoms have emerged as a promising platform for quantum sensing, enabling the detection of electromagnetic fields across a wide frequency range from MHz to THz. Atomic media offer broad tunability, high quality factors, and intrinsic calibration based on the Autler–Townes effect. However, most existing protocols still do not surpass conventional electronics in terms of sensitivity. Nevertheless, atom-based measurements hold the potential to approach the fundamental limits of electromagnetic field detection. The talk will present our efforts to develop novel Rydberg sensing protocols in both hot and cold atomic ensembles, including interaction-assisted measurements and multi-wave mixing techniques.
Point defects are atomic-scale imperfections in otherwise periodic crystals that strongly influence the electrical and optical properties of semiconductors. Once regarded as undesirable, these defects have become key building blocks of emerging quantum technologies, enabling applications in sensing, communication, and information processing.
Quantum technologies are rapidly expanding our ability to control and observe quantum systems, but their impact reaches far beyond quantum computing or particle physics.

Title: 3D Structure Manufacturing of Functionalized Optical Micro-Systems for AI-based Machine Vision Systems
Abstract:
The research aims to develop and validate 3D-manufacturing techniques for the integration of functionalized optical micro-systems directly on top of low-cost CMOS camera sensors, thus bridging the gap between high-performance optical microsystems and mass-market imaging technologies. The research embraces the following core aspects: design and fabrication of 3D micro-optical components (filters, lenses, metasurfaces, etc) using additive and hybrid lithographic processes; functionalization of these micro-structures by specialized processing, materials and their combinations (enabling illumination control, wavelength selectivity, etc.); integration with low-cost CMOS sensors (e.g., from smartphone cameras or industrial vision modules) using scalable alignment and bonding methods compatible with semiconductor packaging; and targeting for the functional prototypes for key use-cases (micro-robotic vision, bio-sensing, environmental monitoring, hyperspectral imaging, etc.).

On November 7 at 14:00, a public scientific seminar entitled "From Light to Structural Architectures: Additive Manufacturing of Inorganic Materials at the Micro–Nano Scale" will be held in Auditorium 306 of the Laser Research Center at the VU Faculty of Physics.
The seminar will be led by Dr Arturo Susarrey-Arce from the University of Twente in the Netherlands. The seminar will be held in English.
Abstract
3D printing, also known as additive manufacturing (AM), is revolutionizing the way we fabricate three-dimensional objects by depositing materials layer by layer according to digital designs. Unlike traditional subtractive techniques, AM offers distinct advantages such as minimized material waste, provides additional design freedom, and the ability to produce highly complex geometries.
This seminar will focus on AM of micro- and nanometric inorganic architectures—particularly glass and ceramics. Special attention will be given to two-photon lithography (TPL), a high-resolution technique that enables the fabrication of intricate three-dimensional architectures with sub-micrometer precision.
We will explore the morphological, structural, and chemical characteristics of these printed architectures, along with their optical functionalities. In particular, the incorporation of lanthanide dopants such as europium will be discussed as a route to achieve tunable luminescent properties.
In addition, the presentation will provide an overview of micro- and nanofabrication research at the University of Twente, highlighting examples such as fractal-inspired architectures for biology and functional designs for electrochemical systems.
About lecturer:
Arturo Susarrey-Arce received his B.Sc. in Chemistry and M.Sc. in Materials Sciences in Mexico. He earned his Ph.D. from the University of Twente, specializing in micro(nano)fabrication and microreactor technologies for electric field driven-catalysis. He conducted two postdoctoral research at the University of Liverpool (UK) and Chalmers University of Technology (SWE). He later became an Assistant Professor at the University of Twente. His research focuses on micro/nanofabrication and 3D-printing of glass and ceramics for optics and health, as well as structural (photo)electrocatalysis for environmental remediation and energy.
