Shape waves in 2D Josephson junctions: exact solutions and time dilation
D. R. Gulevich, F. V. Kusmartsev, S. Savel'ev +2
We predict a new class of excitations propagating along a Josephson vortex in two-dimensional Josephson junctions. These excitations are associated with the distortion of a Josephs…
Negative differential resistivity in superconductors with periodic arrays of pinning sites
V. R. Misko, S. Savel'ev, A. L. Rakhmanov +1
We study theoretically the effects of heating on the magnetic flux moving in superconductors with a periodic array of pinning sites (PAPS). The voltage-current characteristic (VI-c…
Distinguishing quantum from classical oscillations in a driven phase qubit
S. N. Shevchenko, A. N. Omelyanchouk, A. M. Zagoskin +2
Rabi oscillations are coherent transitions in a quantum two-level system under the influence of a resonant perturbation, with a much lower frequency dependent on the perturbation a…
Quantum metamaterials: Electromagnetic waves in a Josephson qubit line
A. L. Rakhmanov, A. M. Zagoskin, Sergey Savel'ev +1
We consider the propagation of a classical electromagnetic wave through a transmission line, formed by identical superconducting charge qubits inside a superconducting resonator. S…
Quantum Tera-Hertz electrodynamics in Layered Superconductors
Sergey Savel'ev, A. L. Rakhmanov, Franco Nori
In close analogy to quantum electrodynamics, we derive a quantum field theory of Josephson plasma waves (JPWs) in layered superconductors (LSCs), which describes two types of inter…
Nonuniform Self-Organized Dynamical States in Superconductors with Periodic Pinning
V. R. Misko, S. Savel'ev, A. L. Rakhmanov +1
We consider magnetic flux moving in superconductors with periodic pinning arrays. We show that sample heating by moving vortices produces negative differential resistivity (NDR) of…
