Quantum lattice transport along an infinitely extended perturbation

Marzieh Baradaran, Pavel Exner, Andrii Khrabustovskyi

We consider a periodic quantum graph in the form of a rectangular lattice with the -coupling of strength in the vertices perturbed by changing the latter at an infinite stra…

Homogenization of the Dirac operator with position-dependent mass

Andrii Khrabustovskyi, Vladimir Lotoreichik

We address the homogenization of the two-dimensional Dirac operator with position-dependent mass. The mass is piecewise constant and supported on small pairwise disjoint inclusions…
