5th Grandmaster Early-Career Workshop in Physics
Prague, Czech Republic
September 7—11, 2020
Following the success of previous workshops organized in Augsburg (2014), Budapest (2015), Vienna (2018) and Split (2019) we are pleased to announce the 5th Grandmaster Early-Career Workshop in Physics. This time the workshop was held at FZÚ – Institute of Physics of the Czech Academy of Sciences, September 7—11, 2020.
The workshop aims at providing a forum for MSc, PhD, and post-doc participants to present their best results for a scientific community, yet in a colloquial atmosphere. Each participant was encouraged to give an oral or poster presentation of his or her work and participate in discussions. Thus, the participants could get insight into on-going research projects in the field of solid-state physics. Moreover, during the workshop all participants had access to a one-day colloquium “Topological defects in ferroelectrics” devoted primarily to exotic domain walls, skyrmions and vortex structures in ferroelectric materials. In the long term, we hope that this workshop can help initiate bilateral or multilateral research programs.

The organizers would like to thank the participants for their contributions and warm atmosphere of the meeting. There were 65 participants from 10 countries at the GEWP 2020 workshop:
40 participants were present on-site (25 from the Czech Republic, 7 from Croatia, 6 from Germany, 1 from Austria, and 1 from Hungary), and 25 participants were using remote access.
Please think to keep 25 percent of the allocated time for questions.
The poster boards were of the A0 format (84 cm wide and 120 cm high). Pins were available on site. All poster presenters were asked to hang their posters on Tuesday.
The GEWP 2020 Workshop was held at the main building of the Institute of Physics of the Czech Academy of Sciences, Na Slovance 1999/2 (entrance from the street Pod Vodárenskou věží), 182 00 Prague 8 (see a map) in the northern part of Prague.
The venue is conveniently located within easy walking distance from the Metro (Underground) station Ládví. It takes only 15 minutes to reach the historical city centre by the Metro.
You are supposed to get your lunch by yourselves. But you should not do it alone! Form groups and decide what to go for. Ask anyone Czech (or Google translate) in the conference room to translate the menu. Groups of 7+ might take quite a long time to serve.

Prague, the capital of the Czech Republic, is well known for its historical monuments, classical architecture and rich cultural heritage that continues today in many theaters, concert halls, opera houses and galleries. Come and discover this wonderful city and walk in the footsteps not only of Franz Kafka and Antonin Dvorak but also of Tycho de Brahe, Johannes Kepler, Bernard Bolzano, Christian Doppler, Albert Einstein, Jaroslav Heyrovsky, Vladimir Prelog and others.

Bus stops are situated directly in front of both airport terminals. Take the bus 119 to the end stop Nadrazi Veleslavin, then take metro (green line A) to Muzeum station, then change to red metro line C and take it to Ládví station. The journey takes approx. 1 hour.
Prague public transport is fast, efficient and frequent. Metro and most daily trams and buses operate every day from 5 AM till midnight. Night trams and buses (line numbers beginning with 9) operate throughout the night. Similar to most capitals, the concentration of picpockets is elevated, be aware in the historical centre as well as on your route from/to the airport.
Tickets:
Basic fare of 32 CZK (approx. 1.20 EUR) entitles the holder to use all means of public transport (Metro, trams, buses and cable car to the Petrin hill) for up to 90 minutes including unlimited number of changes. Cheaper fare of 24 CZK (approx. 0.90 EUR) entitles the holder to use the public transport for up to 30 minutes (daytime only; cheaper rate does not apply in night trams/buses). The ticket must be validated using a yellow box while entering the first bus or tram, or while first entering designated area in Metro. After validation, just keep the ticket with you.
Tickets can be purchased at:
When entering the bus, remember to validate the ticket.
The journey from the airport to Ládví takes around half an hour and should cost around 700 CZK. The taxi rank of both official airport companies (Taxi Praha and Fix Taxi) is situated directly in front of the airport terminal. For the journey back, we strongly recommend ordering a taxi from your hotel reception rather than finding a cab in the street.
All principal railway stations are situated along Metro stations. There are only 3 Metro lines in Prague (A, B, C) so it is not difficult to reach Ládví station (red line C).
If you decide to take a taxi, we strongly recommend ordering one rather than finding a cab in the street. For Taxi Praha, just call 14007 and wait 5–10 minutes until your taxi picks you up.
