Spin fluctuations in quantum dots
A. U. Sharafutdinov, D. S. Lyubshin, I. S. Burmistrov
We explore the static longitudinal and dynamic transverse spin susceptibilities in quantum dots and nanoparticles within the framework of the Hamiltonian that extends the universal…
Statistics of Spin Fluctuations in Quantum Dots with Ising Exchange
D. S. Lyubshin, A. U. Sharafutdinov, I. S. Burmistrov
We explore the effect of single-particle level fluctuations on the Stoner instability in a QD with a strong spin-orbit coupling in the framework of the universal Hamiltonian with t…
Percolation with excluded small clusters and Coulomb blockade in a granular system
A. S. Ioselevich, D. S. Lyubshin
We consider dc-conductivity of a mixture of small conducting and insulating grains slightly below the percolation threshold, where finite clusters of conducting grains are char…
"Burning and sticking" model for a porous material: suppression of the topological phase transition due to the backbone reinforcement effect
A. S. Ioselevich, D. S. Lyubshin
We introduce and study the "burning-and-sticking" (BS) lattice model for the porous material that involves sticking of emerging finite clusters to the mainland. In contrast with ot…
Universality and non-universality in behavior of self-repairing random networks
A. S. Ioselevich, D. S. Lyubshin
We numerically study one-parameter family of random single-cluster systems. A finite-concentration topological phase transition from the net-like to the tree-like phase (the latter…
The phase diagram and the structure of CDW state in high magnetic field in quasi-1D materials: mean-field approach
P. D. Grigoriev, D. S. Lyubshin
We develop the mean-field theory of a charge-density wave (CDW) state in magnetic field and study the properties of this state below the transition temperature. We show that the CD…
