abstract = {We performed measurements at helium temperatures of the
electronic transport in the linear regime in an InAs quantum
wire in the presence of a charged tip of an atomic force
microscope (AFM) at low electron concentration. We show that
at certain concentration of electrons, only two closely
placed quantum dots, both in the Coulomb blockade regime,
govern conductance of the whole wire. Under this condition,
two types of peculiarities—wobbling and splitting—arise
in the behavior of the lines of the conductance peaks of
Coulomb blockade. These peculiarities are measured in
quantum-wire-based structures for the first time. We explain
both peculiarities as an interplay of the conductance of two
quantum dots present in the wire. Detailed modeling of
wobbling behavior made in the framework of the orthodox
theory of Coulomb blockade demonstrates good agreement with
the obtained experimental data.},
