Normal forms for sub-Lorentzian metrics supported on Engel type distributions
Marek Grochowski
We construct normal forms for Lorentzian metrics on Engel distributions under the assumption that abnormal curves are timelike future directed Hamiltonian geodesics. Then we indica…
Invariants and Infinitesimal Transformations for Contact Sub-Lorentzian Structures on 3-Dimensional Manifolds
Marek Grochowski, Ben Warhurst
In this article we develop some elementary aspects of a theory of symmetry in sub-Lorentzian geometry. First of all we construct invariants characterizing isometric classes of sub-…
Small-scale local phenomena related to the magnetic reconnection and turbulence in the proximity of the heliopause
M. Strumik, A. Czechowski, S. Grzedzielski +2
We study processes related to magnetic reconnection and plasma turbulence occurring in the presence of the heliopause (HP) and the heliospheric current sheet. It is shown that the…
Long Gamma Ray Bursts from binary black holes
Agnieszka Janiuk, Szymon Charzyński, Michał Bejger
We consider a scenario for the longest duration gamma ray bursts, resulting from the collapse of a massive rotating star in a close binary system with a companion black hole. The p…
ZnO, ZnMnO and ZnCoO films grown by atomic layer deposition
M. I. Łukasiewicz, A. Wójcik-Głodowska, E. Guziewicz +14
Despite many efforts the origin of a ferromagnetic (FM) response in ZnMnO and ZnCoO is still not clear. Magnetic investigations of our samples, not discussed here, show that the ro…
Optical and magnetic properties of ZnCoO layers
M. Godlewski, M. I. Łukasiewicz, E. Guziewicz +3
Optical and magneto-optical properties of ZnCoO films grown at low temperature by Atomic Layer Deposition are discussed. Strong wide band absorption, with onset at about 2.4 eV, is…
