The Effective Spin Hamiltonian and Phase Separation Instability of the Almost Half-Filled Hubbard Model and Narrow-Band {\it S-f} Model
M. I. Auslender, M. I. Katsnelson
The effective spin Hamiltonian is constructed in the framework of the almost half-filled Hubbard model on the Cayley tree by means of functional integral technique with the use of…
Decoherence by a spin thermal bath: Role of the spin-spin interactions and initial state of the bath
Shengjun Yuan, Mikhail I. Katsnelson, Hans De Raedt
We study the decoherence of two coupled spins that interact with a spin-bath environment. It is shown that the connectivity and the coupling strength between the spins in the envir…
Zero-energy states in corrugated bilayer graphene
M. I. Katsnelson, M. F. Prokhorova
Anomalous quantum Hall effects in single-layer and bilayer graphene are related with nontrivial topological properties of electron states (Berry phases and 2, respectively).…
Chaotic Dirac billiard in graphene quantum dots
L. A. Ponomarenko, F. Schedin, M. I. Katsnelson +4
We report on transport characteristics of quantum dot devices etched entirely in graphene. At large sizes, they behave as conventional single-electron transistors, exhibiting perio…
Half-metallic ferromagnets: From band structure to many-body effects
M. I. Katsnelson, V. Yu. Irkhin, L. Chioncel +2
A review of new developments in theoretical and experimental electronic structure investigations of half-metallic ferromagnets (HMF) is presented. Being semiconductors for one spin…
Magnetic Correlations at Graphene Edges
Oleg V. Yazyev, M. I. Katsnelson
Magnetic zigzag edges of graphene are considered as a basis for novel spintronics devices despite the fact that no true long-range magnetic order is possible in one dimension. We s…
