Lorentz-covariant, unitary evolution of a relativistic Majorana qubit
(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 ... -
Measurement of beauty and charm production in deep inelastic scattering at HERA and measurement of the beauty-quark mass
(Springer Science+Business Media on behalf of the Scuola Internazionale Superiore di Studi Avanzati, 2014)The production of beauty and charm quarks in ep interactions has been studied with the ZEUS detector at HERA for exchanged four-momentum squared 5 < Q^2 < 1000 GeV^2 using an integrated luminosity of 354 pb^{−1}. The ... -
Measurement-induced geometric measures of correlations based on the trace distance for two-qubit X states
(Springer Nature, 2020)We apply the modified Brodutch and Modi method of constructing geometric measures of correlations to obtain analytical expressions for measurement-induced geometric classical and quantum correlations based on the trace ... -

Method for Generating of Archimedean Triangular Connective Operators
(Łódzkie Towarzystwo Naukowe, 2018)Archimedean triangular operators form the basis of the tools for development, analysis and designing of fuzzy systems. They are generated by simple, monotone, single-valued and continuous functions. The basic sets of ... -
Modalities for an Allegorical Conceptual Data Model
(MDPI AG, 2014)Allegories are enriched categories generalizing a category of sets and binary relations. In this paper, we extend a new, recently-introduced conceptual data model based on allegories by adding support for modal operators ... -
Modelling of the non-thermal emission from inhomogeneous jets in active galactic nuclei
(2018)Some active galactic nuclei (AGNs) are strong sources of non-thermal radiation. It is expected that this radiation is produced in collimated outflows of plasma moving with relativistic speeds, the so-called jets. The ... -
Modelowanie procesów radiacyjnych wysokich energii w układach podwójnych gwiazd i ich otoczeniu
(2015)Wyniki obserwacji układów podwójnych gwiazd niektórych typów, przeprowadzone w zakresie promieniowania gamma, wskazują na istotną rolę procesów wysokich energii wewnątrz tych układów lub w ich otoczeniu. Zaobserwowano ... -
Modification of thin films induced by slow heavy ions analysed with PIXE and SRIM
(Springer, 2015-03-17)In the present work the particle induced X-rays (PIXE) emitted during interaction of inert and active slow heavy (HI) ions with specially prepared thin films were measured. Kinematics of the interaction was simulated ... -
Multi-objective optimization of vehicle routing problem using evolutionary algorithm with memory
(AGH Publishing House, 2017)The idea of a new evolutionary algorithm with memory aspect included is proposed to find multiobjective optimized solution of vehicle routing problem with time windows. This algorithm uses population of agents that ... -
Noise resistance of activation of the violation of the Svetlichny inequality
(Springer Nature, 2019)In this paper, we analyze the activation of the violation of the Svetlichny inequality in GHZ states in the presence of noise. We take into account bit flip, phase flip, amplitude damping and depolarizing noisy channels ... -
On the triviality of higher-derivative theories
(North-Holland, 2012)The higher-derivative theories with degenerate frequencies exhibit BRST symmetry [V.O. Rivelles, Phys. Lett. B 577 (2003) 147]. In the present Letter meaning of BRST-invariance condition is analyzed. The BRST symmetry is ... -
Optymalizacja metod analizy danych z teleskopów czerenkowskich CTA
(2020)Teleskopy czerenkowskie są od lat wykorzystywane w astrofizyce naziemnej. Kilka grup badawczych (H.E.S.S., MAGIC, VERITAS) zbudowało układy teleskopów, by szukać źródeł promieniowania kosmicznego w naszej Galaktyce i poza ... -
Perturbative quantum damping of cosmological expansion
(North-Holland, 2014)Perturbative quantum gravity in the framework of the Schwinger–Keldysh formalism is applied to compute lowest-order corrections to expansion of the Universe described in terms of the spatially flat Friedman–Lemaître–Robe ... -
Photoproduction of isolated photons, inclusively and with a jet, at HERA
(Elsevier B.V., 2014)The photoproduction of isolated photons, both inclusive and together with a jet, has been measured with the ZEUS detector at HERA using an integrated luminosity of 374 pb^{−1}. Differential cross sections are presented in ... -
Procesy hadronowe w dwutemperaturowych przepływach akrecyjnych
(2019)W rozprawie badam własności promieniste optycznie-cienkich, dwutemperaturowych przepływów akrecyjnych, które są szeroko rozważane jako wyjaśnienie obiektów z czarnymi dziurami o umiarkowanych i małych jasnościach. Uwzględniam ... -
Quantum gravity stability of isotropy in homogeneous cosmology
(North-Holland, 2011)It has been shown that anisotropy of homogeneous spacetime described by the general Kasner metric can be damped by quantum fluctuations coming from perturbative quantum gravity in one-loop approximation. Also, a formal ... -
Radiative neutron capture cross sections measurement of 70Ge at n_TOF CERN facility and its relevance for stellar nucleosynthesis
(2019)Stellar nucleosynthesis is the name given to the nuclear reactions taking place in stars to create the nuclei of the chemical elements. Elements heavier than iron/nickel are dominantly created by neutron capture reactions. ... -
