Magnetic properties of correlated electrons
Romuald Lemanski
We analyze a system composed of itinerant electrons and localized spins with on-site interactions representing the Hund's first rule. Properties of the system are studied rigorousl…
Reorientation Transition in Single-Domain (Ga,Mn)As
K-Y. Wang, M. Sawicki, K. W. Edmonds +5
We demonstrate that the interplay of in-plane biaxial and uniaxial anisotropy fields in (Ga,Mn)As results in a magnetization reorientation transition and an anisotropic AC suscepti…
Geometry of quantum systems: density states and entanglement
Janusz Grabowski, Marek Kuś, Giuseppe Marmo
Various problems concerning the geometry of the space $u^*(\cH)$ of Hermitian operators on a Hilbert space $\cH$ are addressed. In particular, we study the canonical Poisson and Ri…
On the symmetry of a Preisach map
Marek W. Gutowski
At the very heart of the successful phenomenological model of magnetic hysteresis there is the so called Preisach distribution. In the existing literature it is implicitly assumed,…
Enhanced angular overlap model for f-electron non-metallic systems
Z. Gajek
An efficient method of interpretation of the crystal field effect in non-metallic f-electron systems, the {\it enhanced angular overlap model} (EAOM), is presented. The method is e…
An infinite dimensional affine nil algebra with finite Gelfand-Kirillov dimension
T H Lenagan, Agata Smoktunowicz
We construct a nil algebra over a countable field which has finite but non-zero Gelfand-Kirillov dimension.
