Magnetic tuning of tunnel conductivity
Yu. G. Pogorelov, J. B. Sousa, J. -P. Araujo
Using the simplest two-subband Stoner model, it is shown that the variation of the Fermi energy under applied magnetic field is inverse proportional to the spontaneous magnetizatio…
Exact Solution of Ising Model on a Small-World Network
J. Viana Lopes, Yu. G. Pogorelov, J. M. B. Lopes dos Santos +1
We present an exact solution of a one-dimensional Ising chain with both nearest neighbor and random long-range interactions. Not surprisingly, the solution confirms the mean field…
Adiabatic theory of boundary friction and stick-slip processes
Yu. G. Pogorelov
An adiabatic approach is developed for the problem of boundary friction between two atomically smooth and incommensurate solid surfaces, separated by a monolayer of lubricant atoms…
Fermions under strong repulsion: from multiconnected Fermi surfaces to Fermi condensation
Yu. G. Pogorelov, V. R. Shaginyan
We consider a system of fermions with mass m and model repulsive interaction U(q) = g/\sqrt{q^2 + q_0^2}, where q is the momentum transfer, q_0 the screening constant, and g > 0 th…
Dipolar interactions and anisotropic magnetoresistance in metallic granular systems
J. Viana Lopes, J. M. B. Lopes dos Santos, Yu. G. Pogorelov
We revisit the theory of magnetoresistance for a system of nanoscopic magnetic granules in metallic matrix. Using a simple model for the spin dependent perturbation potential of th…
