Program
Advanced school on asymptotically flat spacetime and celestial holography will take place at the Faculty of Physics, University of Warsaw, from August 28 to September 1, 2023.
Celestial holography employs the framework of two-dimensional (quantum) conformal field theory on the celestial sphere in order to imprint our four-dimensional world on a two-dimensional hologram. It is based on exact mathematical equivalence of soft theorems in QFT with asymptotic symmetries and memory effects in general relativity. This “infrared triangle” offers new insights into quantum gravity and its connections to the standard model of particle physics.
The school will consist of five series of lectures and interactive learning sessions. Each series will consist of four lectures covering the foundations of celestial holography. The school is intended for graduate students, but advanced undergraduates and postdocs entering this rapidly developing research area will also profit from pedagogical lectures and interactive learning sessions.

The lectures will take place in lecture hall 0.03, in the ground floor of the Faculty of Physics.
Travel & transport
Warsaw Chopin Airport – the main airport serving Warsaw. It is located within the city limits, 10 km from the city center, which you can easily reach by a few city buses, a train line, and a taxi.
Warsaw Modlin Airport – another airport, mainly serving budget airlines, located 35 km from the city . It takes around 50 minutes to get to the city center, either by bus and train or a taxi.
Warszawa Centralna Railway Station – the main railway station located in the city center, also serving international trains.
Public transport in Warsaw – the city has a vast transportation network, which includes buses, metro, and trams. You can buy tickets for a single trip (up to either 20 or 75 minutes, with transfers allowed), or multi-day tickets.
Warsaw Public Bike – one of the largest urban bike systems in Europe. It is a good complement to public transport in Warsaw and allows quick navigation through our city. You can register and use at little or (for short enough rides) no cost.
