I was studying Hasan Padamsee's book about RF Superconductivity and I encountered a section in the superconducting essentials' chapter. Dr. Padamsee's intention is to prove why in superconducting state (i.e., $T<T_c$ ), metal impurities does not scatter Cooper pairs, causing resistivity. He says in a normal metals, electron velocity is very high and de Broglie wavelength is comparable to lattice …

For superconducting qubits, Josephson junctions are commonly used to enable the tunneling of Cooper pairs and, more importantly, to introduce the nonlinear energy spectrum required for qubit operation. However, as device dimensions approach the sub-1-nm scale, electron tunneling itself becomes increasingly difficult to suppress and control, and eventually becomes a fundamental issue in convention…

Okayama University researchers detail K₂Cr₃As₃, a novel superconductor exhibiting three spin-triplet phases and a 6.2K transition.

Im solving the London equations for an infinte superconductor in the y>0 region while applying a magnetic field $\vec B$ in the z axis. The solution is well known, the field in the superconductor decays as an exponential characterized by the London penetration lenght $\lambda_L$ , however Im trying to do it properly by solving the London and Maxwell equations. I found that the magnetic fields and…
