Stability and lifetime of antiferromagnetic skyrmions
P. F. Bessarab, D. Yudin, D. R. Gulevich +3
The two-dimensional Heisenberg exchange model with out-of-plane anisotropy and a Dzyaloshinskii-Moriya interaction is employed to investigate the lifetime and stability of antiferr…
Bridging the Terahertz gap for chaotic sources with superconducting junctions
D. R. Gulevich, V. P. Koshelets, F. V. Kusmartsev
We observe a broadband chaotic signal of Terahertz frequency emitted from a superconducting junction. The generated radiation has a wide spectrum reaching 0.7 THz and power suffici…
Exciton Polaritons in a Two-Dimensional Lieb Lattice with Spin-Orbit Coupling
C. E. Whittaker, E. Cancellieri, P. M. Walker +10
We study exciton-polaritons in a two-dimensional Lieb lattice of micropillars. The energy spectrum of the system features two flat bands formed from and photonic orbi…
Josephson Flux Flow Oscillator: the Microscopic Tunneling Approach
D. R. Gulevich, V. P. Koshelets, F. V. Kusmartsev
We elaborate a theoretical description of large Josephson junctions which is based on the Werthamer's microscopic tunneling theory. The model naturally incorporates coupling of ele…
