9:00 AM - 9:40 AM
Room: Star auditorium, chair: Sándor Varró The Wigner function [1] is a quantum mechanical distribution function and lives in phase space. It allows us to evaluate the expectation values of symmetrically ordered operators. Moreover, it is an extremely useful tool [2] to analyze phenomena at the interface of classical and quantum physics. In the present talk, we focus on three such topics: (i) The equivalence principle of general relativity viewed from quantum phase space [3], (ii) the Kasevich-Chu interferometer described by the Wigner function [4], and (iii) the connection between a logarithmic phase singularity, tunneling through a quadratic barrier [5], and Hawking radiation [6].

9:40 AM - 10:20 AM
Room: Star auditorium, chair: Sándor Varró A hundred years ago, the sun-Earth connection was of interest to only a small number of scientists. Solar activity had little effect on daily life. Today, a single strong solar eruption could bring civilization to its knees. Modern society has come to depend on technologies sensitive to solar radiation and geomagnetic storms. Particularly vulnerable are power grids, interplanetary robotic and human exploration, satellite operations and communications, and GPS navigation. These technologies are woven into the fabric of daily life, from health care and finance to basic utilities. This presentation will describe the basic processes controlling space weather together with observational, modeling and forecasting efforts.

11:00 AM - 11:40 AM
Room: Star auditorium, chair: Péter Lévai One of the most remarkable possibilities of General Relativity concerns gravitational collapse to black holes, leaving behind a geometry with light rings, ergoregions and horizons. These peculiarities are responsible for uniqueness properties and energy extraction mechanisms that turn black holes into ideal laboratories of strong gravity, of particle physics (yes!) and of possible quantum-gravity effects. I will review the status of black holes, in light of gravitational-wave observations in the last few years.
11:40 AM Attosecond science - future directions - Ferenc Krausz

11:40 AM - 12:20 PM
Room: Star auditorium, chair: Péter Lévai Attosecond metrology emerged on the turn of the milleneum and enabled scientists to observe fundamental electronic processes in atoms, molecules, or solids in real time. Attosecond techniques now permit measurement of the oscillating electric field of light from the infrared to the ultraviolet. We will discuss how this unprecedented technical capability may help advance electronic signal processing towards its ultimate speed limit and allows sensing changes in the molecular composition of human blood, for health monitoring.

5:00 PM - 5:40 PM
Room: Star auditorium A linear response of quantum electrons is well studied and for that well developed theoretical and computational methods computing the linear response properties are available. However, recent introduction of THz lasers and the novel seeding technique to reach high intensities [1] allow us to generate nonlinear response of quantum electrons in extended systems. Therefore, in this talk the results will be presented for the non-linear density response of quantum electrons and the applicability of various approximations and methods for extended systems will be discussed [3-5]. The utility of the quantum Wigner distribution function for the analytic solution of the non-linear response problem of arbitrary order will be presented [5]. [1] B.K. Ofori-Okai, et al., J.
