Performance optimization of cascaded traveling wave Josephson parametric amplifiers
Ilari Lilja, Ekaterina Mukhanova, Stanislav Khaldeev +3
Traveling-wave parametric amplifiers (TWPAs) based on Josephson metamaterials provide broadband gain with near-quantum-limited added noise. Whereas long nonlinear metamaterial devi…
Phase-sensitive cascade quantum amplifier with nearly noiseless operation
Ilari Lilja, Ekaterina Mukhanova, Michael Perelshtein +5
Phase-sensitive parametric devices enable quadrature-selective amplification with the potential for sub-quantum-limited noise performance. In this work, we investigate the operatio…
Breaking of Ginzburg-Landau description in the temperature dependence of the anisotropy in the nematic superconductor
M. I. Bannikov, R. S. Akzyanov, N. K. Zhurbina +5
Nematic superconductors are characterized by an apparent crystal symmetry breaking that results in the anisotropy of the in-plane upper critical magnetic field . The symmet…
