(2023)W pracy przedstawione zostały badania, związane z naniesioną cienką warstwą (~3 nm) metali szlachetnych (Au i Pt) na powierzchnię rutylu TiO2(001), stanowiące domknięcie dotychczasowych badań. Eksperyment miał na celu ... -
XPS W4f and Mo3d spectra for Plasma-Treated 2D TMDs, 2020/38/E/ST3/00293, SONATA BIS (dataset)
(2022)Data includes sets of XPS spectra for 2D MoS2 and WS2 samples. Each set contains data for reference samples and data for plasma functionalized samples with two different reaction times. The spectra are supplemented with ... -
Results of KPFM measurements of the MoO3 monolayer, 2020/38/E/ST3/00293, SONATA BIS (dataset)
Kowalczyk, Dorota
(2022)
The data includes images of the topography and contact potential distribution for the HOPG surface covered with the MoO3 monolayer. The surface coverage is less than 1ML, allowing the substrate to be partially exposed. The ... -
Graphene heterostructures with transition metal oxides – investigations of morphology and electronic structure towards applications in organic electronics
(2022)The unique electrical, optical and mechanical properties of graphene make it attractive as a flexible transparent electrode for applications in organic electronics, e.g. organic light emitting diodes (OLEDs). However, the ... -
Teoretyczne badanie własności nanomagnetyków kwantowych metodą dokładnej diagonalizacji
(2022)Cel pracy stanowiło teoretyczne zbadanie własności wybranych układów magnetyków kwantowych o skończonych rozmiarach (nanomagnetyków o postaci klasterów złożonych z niewielu spinów). Założone zadanie zrealizowano modelując ... -
High-energy radiation from low-luminosity accreting black holes
(2018)This PhD thesis includes theoretical and observational studies of γ-ray emission from radio-quiet accreting black holes. The theoretical motivation for the search of γ-ray emission from such sources concerns the considerable ... -

Analysis of the mass composition of high-energy cosmic ray
(IOP Publishing, 2013)This paper analyses mass composition of high-energy cosmic ray, comparing simulation and experimental results. Using the nuclear interaction models QGSJET-II and Sibyll, we simulate EAS initiated by the primary nuclei ... -
Wigner functions and coherent states for the quantum mechanics on a circle
Kowalski, Krzysztof; (IOP Publishing, 2021)
The Wigner functions for the coherent states of a particle on a circle are discussed. The nontrivial analytic forms of these functions are derived. The classicality of the circular coherent states existing in the literature ... -
Artificial Neural Network as a FPGA Trigger for a Detection of Neutrino-Induced Air Showers
; Głas, Dariusz; Szadkowski, Zbigniew (IntechOpen, 2016)
Neutrinos play a fundamental role in the understanding of the origin of ultrahigh-energy cosmic rays (UHECR). They interact through charged and neutral currents in the atmosphere generating extensive air showers. However, ... -
Lorentz-covariant, unitary evolution of a relativistic Majorana qubit
Smoliński, Kordian; ; ; (Springer Nature, 2018)
We formulate a covariant description of a relativistic qubit identified with an irreducible set of quantum spin states of a Majorana particle with a sharp momentum. We treat the particle’s four-momentum as an external ... -
An analysis method for data taken by Imaging Air Cherenkov Telescopes at very high energies under the presence of clouds
(Elsevier, 2020)The effective observation time of Imaging Air Cherenkov Telescopes (IACTs) plays an important role in the detection of γ-ray sources, especially when the expected flux is low. This time is strongly limited by the atmospheric ... -
An Extremum Principle for Smooth Problems
Idczak, Dariusz; Walczak, Stanislaw (MDPI, 2020)
We derive an extremum principle. It can be treated as an intermediate result between the celebrated smooth-convex extremum principle due to Ioffe and Tikhomirov and the Dubovitskii–Milyutin theorem. The proof of this ... -
The covariance of chiral fermions theory
Gonera, Cezary; ; ; Gonera, Joanna ; Kosinski, Piotr ; (Springer Nature, 2019)
The quasiclassical theory of massless chiral fermions is considered. The effective action is derived using time-dependent variational principle which provides a clear interpretation of relevant canonical variables. As a ... -
