In order to gain a deeper understanding of the quantum criticality in the explicitly staggered dimerized Heisenberg models, we study a generalized staggered dimer model named J0-J1-J2 model, which corresponds to the staggered J-J' model on square lattice and honeycomb lattice when J1/J0 equals 1 and...

Two-dimensional periodic array of quantum dots with two laterally coupled leads in a magnetic field is considered. The model of electron transport through the system based on the theory of self-adjoint extensions of symmetric operators is suggested. We obtain the formula for the transmission coeffic...
