XXIV Czech-Polish seminar

Structural and ferroelectric phase transitions

Harrachov, Czech Republic
May 23 – 27, 2022

The idea of regular scientific meetings of physicists involved in studies of ferroelectrics and phase transitions in Poland and Czechoslovakia followed inevitably from the success of first such an event in Błażejewko in 1979. The Seminar was organized in collaborating of the Department of Dielectrics of the Institute of Physics of Czechoslovak Academy of Sciences and the Ferroelectric Lab of the Institute of Molecular Physics of Polish Academy of Sciences. The Seminars are an international forum for presentation of recent results, unconstrained discussions and initiating of joint studies. This conference series results not only in scientific integration but also in close cooperation and friendship. The bianual event usually brings together about 100–120 participants in a proportion: approximately one third from the Czech Republic, one third from Poland and the rest from other countries.

The venue of XXIV Czech–Polish seminar was Harrachov, Czech Republic. The Harrachov town and mountain resort is located at the altitude of 665 m in the Giant Mountains range of the Sudetes (Krkonoše), in the valley of the Mumlava river below the Čertova mountain. The town is located directly at the Czech–Polish border. The town consisting of four parts and villages (Harrachov, Mýtiny, Nový Svět and Rýžoviště) has about 1,300 inhabitants.

The first written reference dates back to the 17th century when German settlers founded a village Dörfl. Harrachov has been known for its glass production which dates back to the 14th century. In 1890s, first pair of skis was imported to the country which started the tradition of winter sports in Harrachov. In 1920, first ski jumping hills were built. The first international skiing championship was organised in 1923. Harrachov still remains a popular skiing resort.

Giant Mountains

The Giant Mountains (Krkonoše in Czech, Karkonosze in Polish, Riesengebirge in German) is a mountain range located in the north of the Czech Republic and the south-west of Poland, part of the Sudetes mountain system (part of the Bohemian Massif). The Czech-Polish border, which divides the historic regions of Bohemia and Silesia, runs along the main ridge. The highest peak Sněžka (1,603 m) is the highest peak in the Czech Republic.


Hotel Sklar

Accommodation was provided in Resort Sklář****, Harrachov 520, 512 46 Czech Republic. The hotel conveniently located close to the town centre offers accommodation in 171 rooms. There is a restaurant and bar, a hotel wellness centre with a heated swimming pool, sauna, steam bath, hot tub and many types of massages available. The resort offers plenty of sport activities. Animated video programs are available for children.


Scope and Program

Thematical scope of the XXIV Czech–Polish Seminar included all its traditional subjects:

Invited speakers

Tutorial lectures

In order to promote the scientific development of our younger colleagues, the conference was expanded by a series of tutorials. The main part of the tutorials started in the morning on Monday, May 23 at the Institute of Physics in Prague and included lab visits. This arrangement also provided an opportunity to see our beautiful capital the day before. A bus transfer to the conference location was secured.

List of tutorials:

Young Researcher Competition

All students had an opportunity to take part in a Clip Session to promote their poster to demonstrate their ability to introduce their research orally in two minutes to a broad audience and discuss in the follow-up poster session. The best three competitors were awarded. The competition was open for Master and PhD students.


Technical program of the XXIV Czech–Polish Seminar was scheduled from the afternoon on Monday, May 23 till the lunch on Friday, May 27. Wednesday afternoon was reserved for sightseeing tours.

Free time is scheduled on Wednesday, May 25 after lunch. You can plan your own activities, or we can offer you four organized excursions. There will be a limited number of participants for the excursion to the glassworks. Hiking options will be organized on tourist pathways (partially asphalted, partially unpaved surface), comfortable walking shoes are recommended. In principle, options 1 and 2 can be combined.

1) Visit to the Glassworks and Museum of Glass (60 people max.)

As part of an excursion to the glassworks, you will first visit their metallurgical production, a historic glass grinding mill, a glass museum, and you can also see the chapel of St. Elizabeth with an altar made of Venetian mirrors and a functional glass bell. Excursion length 1 h, departure from the hotel at 13:45 (short walk about 1.5 km). After the excursion, it is possible to visit the company’s glass shop with the possibility of buying local products and the local brewery restaurant.

2) Tourist walk: Small Harrachov hike

Route length: 6 km. Time required: 2—3 hours. The route runs outside the busy city center. Along the way you can't miss one of the natural beauties of Harrachov — Mumlava waterfall where you can refresh in the nearby buffet “Mumlavská bouda” (Mumlava cottage). This part of the route leads on an asphalted surface. The second part continues on an unpaved forest path above the “Zákoutí complex” with a swimming pool, mini golf, tennis and a possibility of small snacks. The road continues along side streets of Harrachov with a beautiful view of the “Čertova hora” (Devil’s Mountain) and the ski jumps.

3) Tourist walk: Medium Harrachov hike

Route length: approx. 10 km. Time required: 3—4 hours. Slightly difficult route. The surface of the route is mostly formed by an asphalted road, some sections are formed by unpaved forest roads. The route will take you to the middle ski jumps, further along the bridge over the river Mumlava river and continues through the forest to the cableway called “Rýžoviště”. Here begins a quiet part of the road that will take you to the river Mumlava and along the river you will gradually descend to the Mumlava waterfalls. At the end of the trip you will pass tennis courts, a swimming pool area and a moment later you will see beautiful views of “Čertova hora” (Devil’s Mountain) with large ski jumps.

4) Tourist walk: Great Harrachov hike

Route length: approx. 15 km. Time required: 4—5 hours. Moderately difficult route. The route is an extended version of the Medium Harrachov hike; it is the same until it reaches the Mumlava River. Here it is possible to turn right and go to the tourist point called “Krakonošova snídaně” (Krakonoš breakfast). Then back along the same path and downstream, you will gradually descend to Mumlava waterfalls. Furthermore, the route is again the same as in the case of the Medium Harrachov hike mentioned above.
