Electrocaloric effect in cubic Hubbard nanoclusters
(Springer Nature, 2018)
In the paper a computational study of the electrocaloric efect is presented for a cubic nanocluster
consisting of 8 sites. The system of interest is described by means of an extended Hubbard model in
external electric ...
The Carbon Footprint Methodology in CFOOD Project
(Polish Academy of Sciences Committee of Electronics and Telecommunications, 2020)
In the paper, the research on the process of
optimizing the carbon footprint to obtain the low-carbon
products is presented. The optimization process and limits were
analyzed based on the CFOOD project co-financed by ...
The covariance of chiral fermions theory
(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 ...
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
; Walczak, Stanislaw 
(MDPI, 2020)
(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 ...
Lorentz-covariant, unitary evolution of a relativistic Majorana qubit
Smoliński, Kordian ; ; ; (Springer Nature, 2018)
; ; ; (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 ...
Elastic scattering in geometrical model
(Elsevier B.V., 2016)
The experimental data on proton–proton elastic and inelastic scattering emerging from the measurements at the Large Hadron Collider, calls for an efficient model to fit the data. We have examined the optical, geometrical ...
Constrains for non-standard statistical models of particle creations by identified hadron multiplicity results at LHC energies
(Springer Berlin Heidelberg, 2014)
We analyzed the identified hadron multiplicity predictions of the modified thermodynamical model of the multiparticle production processes with non-extensive statistic. The replacement of the standard Boltzmann exponential ...
Scaling violation and the inelasticity of very high energy proton–proton interactions
(North-Holland, 2011)
The pseudorapidity measurements at LHC, although in the central region only, allows us to perform preliminary tests of the multiparticle production extrapolation formula inspired by the analysis of recent cosmic ray data. ...
Thermal induced structural and magnetic transformations in Fe_{73.5−x}Ce_{x=0,3,5,7}Si_{13.5}B_9Nb_3Cu_1 amorphous alloy
; ; Gwizdałła, Tomasz ; ; (Springer Netherlands, 2013)
; ; (Springer Netherlands, 2013)
Structural and magnetic properties of amorphous and partly crystallized Fe_{73.5−x}Ce_{x=0,3,5,7}Si_{13.5}B_9Nb_3Cu_1 alloys, were analysed in the temperature ranging from RT to 800 °C with scanning calorimetry and ...
