Hamiltonian formalisms and symmetries of the Pais–Uhlenbeck oscillator
(Elsevier B.V., 2014)
The study of the symmetry of Pais–Uhlenbeck oscillator initiated in Andrzejewski et al. (2014) [24] is continued with special emphasis put on the Hamiltonian formalism. The symmetry generators within the original Pais and ...
Generalized Niederer’s transformation for quantum Pais–Uhlenbeck oscillator
(Elsevier B.V., 2015)
We extend, to the quantum domain, the results obtained in [Nucl. Phys. B 885 (2014) 150] and [Phys. Lett. B 738 (2014) 405] concerning Niederer’s transformation for the Pais–Uhlenbeck oscillator. Namely, the quantum ...
Conformal Newton–Hooke algebras, Niederer's transformation and Pais–Uhlenbeck oscillator
(Elsevier B.V., 2014)
Dynamical systems invariant under the action of the l-conformal Newton–Hooke algebras are constructed by the method of nonlinear realizations. The relevant first order Lagrangians together with the corresponding Hamiltonians ...
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 ...
