W dniu 6.12.2019 gościem Wydziału Fizyki i Astronomii była Irene Tovar Hernández z University of Extremadura, która wygłosiła wykład pod tytułem: Tracking the solar activity from the University of Extremadura
Irene studiowała na naszym wydziale w roku 2017/18 w ramach programu Erasmus+.
Zapraszamy na wykłady Profesora George Jorjadze (Free University of Tbilisi). Prof. Jorjadze jest gościem Wydziału Fizyki i Astronomii w ramach programu Erasmus+.
1. Deformations of 2d CFT
10.12.2019, godz. 11:15; Szafrana A-4, 106, (wykład w ramach Seminarium Instytutowego)
2. Liouville theory as a model of 2d gravity
10.12.2019, godz. 15:15; Szafrana A-4, 214
3. Reflection amplitude in Liouville theory
10.12.2019, godz.16:05; Szafrana A-4, 214
Abstract of the talks
1. We analyze symmetries of 2-dimensional conforml field theories and their possible integrable deformations. We construct the T-bar T deformed Hamiltonian in a closed form for any 2d CFT and show its relation to string dynamics.
Abstract of the Lecture 1
2. We show that the Einstein-Hilbert action in 2d is degenerated and show that the constant curvature 2d manifolds in the conformal coordinates are described by the Liouville equation. We derive the general solution of the Liouville equation using its conformal symmetry. We then classify Liouville fields on a cylinder and describe their physical content.
Absract of the Lecture 2
3. We investigate scattering problem in Liouville theory and show that the S-matrix is non-trivial. We construct the Heisenberg operators for the Liouville field exponentials and calculate the reflection amplitude for the homogeneous Liouville field configurations.
Report on Erasmus+ training
(by Kamil Haładyn)
This Summer I had the possibility to participate in 2 months practice on Tenerife with the company Uroborus SL (Travel Tenerife and Astronomy and Science Centre). I've joined the international team of astronomers and those who make the company running. During this period I've worked as an astronomer assistant. I had the unprecedented possibility to practice my knowledge in the field of astronomy, both directly by operating the telescopes and by finding astronomical objects. The possibility to work on the best sky in the whole World gave me a new perception of practical astronomy. After coming back to Poland even with low visibility I am able to recreate the star patterns and find objects not visible with the naked eye. Additionally working manually with the telescopes (not using computerised robotic equipment) gave me the best training in woking with all kind of telescopes as well as being able to perform the maintenance. After 2 months of working with all kinds of people with absolutely different backgrounds I've learned to be able to explain the most sophisticated issues in the way pleasurable and understandable by everyone. I am now ready to perform my own astronomical shows and share my passion with others.
During my practice I was also involved in every day life of the company. That gave me great understanding of the issues each person deals with as well as how aspects I would expect unimportant, influence the working of a company. I've learnt characteristics of different areas such as promotion and marketing, IT, maintenance, transport, logistics, psychology of teamwork and management and even basics of finances. I was shocked how much management and logistics is required for accomplishing each task. I think I've returned home more experienced, matured and responsible than I would have expected. In my personal opinion this kind of practices that the program Erasmus provided for me, should be implemented more often. I find it the most efficient way of learning and confronting the theoretical knowledge and expectations of young and basically unexperienced student with the realities of a job he/she may have undertake. The most important fact is that thanks to the international relations with both team and clients, I have far better grasp of the way different people react to different things as well as I have realised how much cooperation is important in achieving ones goals. I saw astronomy as fully scientific subject while now I understand that working in astronomy, demands interdisciplinary team in which everybody's skills and knowledge are equally important. I understand now that this knowledge of mine relates to not only astronomy but all aspects of science. With this new understanding I am ready to continue the development of UZ Space Club, the student association I am the president of, by advertising our need of representants of various different fields of expertise starting with management, through different areas of science such as biology, geology, medicie, as far as arts. Thanks to my time spent with Uroborus SL, I now know that to pursue science, not only scientists are needed. I have learned that science will always need assistance of managmet, social sciences and many more more experts to be able to develop efficiently. What is more important I feel that I have also learned to communicate and respect even those I don't fully understand.
W dniach 23-25.01.2017 Profesor George Jorjadze z Free University of Tbilisi wygłosił cztery wykłady:
- Elementary particles and typical scales in high-energy physics
- String theory and critical dimensions
- Lorentz transformations and relativistic kinematics
- Lagrangian, conservation laws, quantization
Profesor Jorjadze był gościem Wydziału Fizyki i Astronomii w ramach programu Erasmus+. Jego wykłady były adresowane do studentów, doktorantów. Wykład: String theory and critical dimensions został wygłoszony w ramach seminarium wydziałowego.
W roku 2015/16 na Wydziale Fizyki i Astronomii UZ w ramach programu Erasmus+ studiowało dwudziestu studentów z Hiszpanii, Wietnamu, Gruzji, Ukrainy i Grecji. Nasi goście kształcili się na wszystkich trzech stopniach nauczania tworząc międzynarodowe grupy dla których zajęcia zorganizowane były w języku angielskim. Trójka studentów z Hiszpanii spędziła na WFiA cały rok akademicki, zaś pozostali jeden semestr.
