Large linear magnetoresistivity in strongly inhomogeneous planar and layered systems
S. A. Bulgadaev, F. V. Kusmartsev
Explicit expressions for magnetoresistance of planar and layered strongly inhomogeneous two-phase systems are obtained, using exact dual transformation, connecting effective co…
Exact Results for Conductivity of 2D Isotropic Heterophase Systems
S. A. Bulgadaev
The duality relation for the effective conductivity sigma_{e} of 2D isotropic heterophase systems is used for obtaining the exact results for sigma_{e} at arbitrary number of phase…
Duality and Effective Conductivity of Two-dimensional Two-phase Systems
S. A. Bulgadaev
The possible functional forms of the effective conductivity sigma_{eff} of the randomly inhomogeneous two-phase system at arbitrary values of concentrations are discussed. A new fu…
Topological phase transitions in two-dimensional systems with internal symmetries
S. A. Bulgadaev
Possible generalizations of the topological (or Berezinskii-Kosterlitz-Thouless) phase transition on multicomponent 2D systems with nontrivial vector homotopic group pi_1 are consi…
Topological phase transitions in low-dimensional systems
S. A. Bulgadaev
A general theory of the Berezinsky-Kosterlitz-Thouless (BKT) type phase transitions in low-dimensional systems is proposed. It is shown that in d-dimensional case the necessary con…
