This two-day conference offers a unique opportunity to learn about the latest research conducted at the Extreme Light Infrastructure (ELI) science centre, open access possibilities, and cutting-edge laser plasma technologies. The event is intended for researchers, PhD students, engineers, and anyone interested in ultrafast laser sources, the effects of radiation on biological systems, advances in laser-driven particle acceleration, and the application of artificial intelligence in physics experiments.

The seminar will present experimental studies of wavepacket propagation in a dissipative engineered quantum chain. The work implements a non-Hermitian synthetic lattice with an abrupt interface between dissipative and non-dissipative sub-chains, using the hyperfine manifold states of an Rb-87 Bose–Einstein condensate. By tuning the dissipation strength, the researchers observed the crossover between ballistic propagation, near-perfect absorption, and quantum Zeno reflection. Numerical simulations revealed that optimal absorption occurs when tunnelling and dissipation are properly matched.

The lecture will be delivered by Prof. Oleg Chalykh (University of Leeds, UK).

Abstract
For a linear ODE in the complex domain, its singular point x=x0 is called an apparent singularity if all solutions to the ODE are meromorphic near this point. Equivalently, x=x0 is a regular singular point and the monodromy around x0 is trivial. What can one say about ODEs whose finite singular points are all apparent? I will give an answer for the case when x=∞ is an irregular singularity of the mildest kind (of Poincaré rank one). I will then discuss an analogous problem for difference equations. Finally, I'll indicate how these results can be applied to give a geometric interpretation of the algebraic Bethe ansatz for the quantum Gaudin and XXZ models. This is based on ongoing projects with N. Belousov, A. Liashyk, and Y. Xie.

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.
