Ultra-complex conductivity diagrams in the nearly free electron approximation
A. Ya. Maltsev
We investigate the possibility of the emergence of ultra-complex conductivity diagrams in the nearly free electron approximation for metals with cubic symmetry. Estimates show that…

On chaotic regimes of conductivity behavior in the tight-binding approximation
A. Ya. Maltsev
We investigate the probability of detecting the most nontrivial conductivity behavior regimes in metals whose electron spectrum is described by the tight-binding approximation. The…

On the level lines of two-layer symmetric potentials
A. Ya. Maltsev
We consider the behavior of level lines of two-dimensional potentials, which play an important role in the physics of ``two-layer'' systems. Potentials of this type are quasiperiod…
