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. ...
Superaktywacja nierówności Svetlichnego w układach wielocząstkowych
(2017)
Rozprawa doktorska obejmuje analizę aktywacji łamania nierówności Svetlichnego w układach trzycząstkowych zarówno dla stanów czystych jak i dla mieszanych stanów zaszumionych.
W ostatnich latach nielokalne korelacje ...
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 ...
Hidden Lorentz symmetry of the Hořava–Lifshitz gravity
(North-Holland, 2014)
In this Letter it is shown that the Hořava–Lifshitz gravity theory admits Lorentz symmetry preserving preferred global time foliation of the spacetime.
β decay of 6He into the α+d continuum
(American Physical Society, 2015)
The rare β-decay channel of 6He into the α+d continuum was investigated at the REX-ISOLDE facility. Bunches of postaccelerated 6He ions were implanted into the optical time projection chamber (OTPC), where the decays with ...
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 ...
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 ...
Conformal Newton–Hooke symmetry of Pais–Uhlenbeck oscillator
(North-Holland, 2014)
It is demonstrated that the Pais–Uhlenbeck oscillator in arbitrary dimension enjoys the l -conformal Newton–Hooke symmetry provided frequencies of oscillation form the arithmetic sequence ωk=(2k−1)ω1, where k=1,…,n, and ...
