First-principles perspective on magnetic second sound
Paweł Buczek, Nadine Buczek, Giovanni Vignale +1
The fluctuations of the magnetic order parameter, or longitudinal spin excitations, are investigated theoretically in the ferromagnetic Fe and Ni as well as in the antiferromagneti…

An extinction rule for a class of 1D quasicrystals
Pawel Buczek, Janusz Wolny
We study decorated one-dimensional quasicrystal obtained by a non-standard projection of a part of two-dimensional lattice. We focus on the impact of varying relative positions of…

Physical space description of decorated quasicrystals
Pawel Buczek, Janusz Wolny
In this paper the systematic method of dealing with the arbitrary decorations of quasicrystals is presented. The method is founded on the average unit cell formalism and operates i…
