We explain the emergence of zero field steps (ZFS) in a Frenkel-Kontorova (FK) model for a
1D annular chain being a model for an annular Josephson junction array. We demonstrate …

Ratchet of kink under harmonic ac driving force in the discrete Klein–Gordon model with
asymmetric potential and with a damping term is investigated numerically. A particular …

We consider an array of inductively coupled Josephson junctions with a fast impurity (a
junction with a smaller value of the critical current) and study the consequences of imposing …

Vortex dynamics have been investigated numerically in a double-ring annular ladder
composed of Josephson ratchet network along the circular direction. One repeat unit of the …

The influence of curvature on kink creation during continuous phase transition in a long
Josephson junction is considered. An example of a Josephson junction with constant …

Построена дискретная модель Клейн-Гордона с асимметричным локальным
потенциалом, допускающая кинковые решения, свободные от потенциала Пайерлса …

We present numerically the motion of vortices placed in an annular Josephson ladder which
has a periodic ratchet potential along the annular direction. The ratchet characteristics are …

We study numerically the thermal depinning of single fluxons in ratchet Josephson junction
rings. Rings are made of 9 junctions with 3 different critical currents. We present results for a …

A discrete Klein-Gordon model with asymmetric potential that supports kinks free of the
Peierls-Nabarro potential (PNp) is constructed. Undamped ratchet of kinks under harmonic …
