ICSM 2025 conferenceWednesday, 05 March 2025 10:57 |
10th International Conference on Superconductivity and Magnetism - ICSM 2025 will be held in Fethiye-Oludeniz, Turkey from 26th April to 3rd May 2025. This conference will cover a wide range of physics topics, including superconductivity, magnetism, and quantum materials and technological communities, and create networking opportunities and strengthen connections between all career levels. This year again, Dr. Shiv Singh from our Institute is organizing a special session: “Advances in Iron-based Superconductors: Growth, fundamental and applied research”. You can find more details about this session here. Furthermore, in this conference, Dr. Shiv Singh will have an invited talk entitled "Impurity Effects on the Superconducting Properties of Stoichiometric CaKFe4As4 by Conventional and High-pressure Growth Methods”. Recently, Dr. Singh’s research team has proved that the high-pressure growth technique can be an effective method to enhance the superconducting properties of high-Tc superconductors as well as the sample quality. More details about the program and the speakers can be found here.

Insights into spontaneous and piezoelectric polarization in nitridesTuesday, 15 April 2025 13:44 |
We are pleased to inform about the work on spontaneous and piezoelectric polarization published recently in Materials: P. Strak, P. Kempisty, K. Sakowski, J. Piechota, I. Grzegory, E. Monroy, A. Kaminska, S. Krukowski, Spontaneous and Piezo Polarization Versus Polar Surfaces: Fundamentals and Ab Initio Calculations, Materials 2025, 18(7), 1489; https://doi.org/10.3390/ma18071489 The study discusses the fundamental properties of spontaneous and piezoelectric polarization as well as surface polarization. It has been shown that Landau’s definition of polarization as dipole density can be applied to infinite systems. Two components of polarization were distinguished: bulk polarization and surface polarization. This division is consistent with numerous experimental data. A local model of spontaneous polarization was introduced and used to calculate spontaneous polarization in the form of electric dipole density. This model correctly predicted the values of spontaneous polarization for wurtzite-type nitride semiconductors. At the same time, the model showed zero polarization for the zinc blende lattice. The values of spontaneous polarization obtained for wurtzite group III nitrides were consistent with previous calculations carried out using the Berry phase method. First-principles calculations for wurtzite nitride superlattices using the Heyd–Scuseria–Ernzerhof approximation were performed to calculate polarization fields in regularly strained lattices, showing good agreement with the polarization results. These data were used to determine the piezoelectric parameters of wurtzite nitrides, yielding values consistent with earlier results.
Recognition for Dr. Konrad SakowskiFriday, 04 April 2025 11:17 |
We are proud to announce that an employee of our Institute, Dr. Konrad Sakowski, has been recognized by the Rector of the University of Warsaw for inspiring scientific research and outstanding achievements. The ceremonial presentation of diplomas took place at the Kazimierzowski Palace on Wednesday, April 2., 2025. Dr. Konrad Sakowski, in addition to his scientific work at the IWC PAN, is also an assistant professor at the Faculty of Mathematics, Computer Science and Mechanics of the University of Warsaw. We congratulate Konrad on this distinction and wish him continued success in his work. We are proud that he is part of our team.
WBCGE 2025Tuesday, 11 February 2025 22:46 |
Institute of High Presdsure Physics PAS and the Polish Society for Crystal Growth (PTWK) is pleased to invite all scientists involved in bulk crystal growth, epitaxy and characterization to the Workshop on Bulk Crystal Growth and Epitaxy (WBCGE), that will take place at our Institute (IWC PAN) in Warsaw on May 15-16, 2025. WBCGE Workshop will be chaired by Prof. Michał Leszczyński (PTWK President, IWC PAN) and Prof. Dorota Pawlak (CEO of Ensemble3). It will be an excellent opportunity for scientific development, as well as to expand the network of contacts in the rapidly developing field of crystal growth and epitaxy.
