Fragmentation from group interactions: A higher-order adaptive voter model
Nikos Papanikolaou, Renaud Lambiotte, Giacomo Vaccario
The adaptive voter model allows for studying the interplay between homophily, the tendency of like-minded individuals to attract each other, and social influence, the tendency for…
Perturbative dynamic renormalization of scalar field theories in statistical physics
Nikos Papanikolaou, Thomas Speck
Renormalization is a powerful technique in statistical physics to extract the large-scale behavior of interacting many-body models. These notes aim to give an introduction to pertu…
Transport properties of single atoms
Alexei Bagrets, Nikos Papanikolaou, Ingrid Mertig
We present a systematic study of the ballistic electron conductance through sp and 3d transition metal atoms attached to copper and palladium crystalline electrodes. We employ the…
Conduction eigenchannels of atomic-sized contacts: Ab initio KKR Green's function formalism
Alexei Bagrets, Nikos Papanikolaou, Ingrid Mertig
We develop a formalism for the evaluation of conduction eigenchannels of atomic-sized contacts from first-principles. The multiple scattering Korringa-Kohn-Rostoker (KKR) Green's f…
Monte Carlo simulations of ferromagnetism in p-CdMnTe quantum wells
D. Kechrakos, N. Papanikolaou, K. N. Trohidou +1
Monte Carlo simulations, in which the Schrodinger equation is solved at each Monte Carlo sweep, are employed to assess the influence of magnetization fluctuations,short-range antif…
Magnetoresistance of atomic-sized contacts: an ab-initio study
Alexei Bagrets, Nikos Papanikolaou, Ingrid Mertig
The magnetoresistance (MR) effect in metallic atomic-sized contacts is studied theoretically by means of first-principle electronic structure calculations. We consider three-atom c…
