Magnetic field-induced "mirage" gap in an Ising superconductor

Superconductivity is commonly destroyed by a magnetic field due to orbital or Zeeman-induced pair breaking. Surprisingly, the spin-valley locking in a two-dimensional superconductor with spin-orbit interaction makes the superconducting state resilient to large magnetic fields. We investigate the spectral properties of such an Ising superconductor in a magnetic field taking into account disorder. The interplay of the in-plane magnetic field and the Ising spin-orbit coupling leads to noncollinear…

Engineering the output power of a one-atom laser

Hybrid systems combine elemental components with distinct tunable properties, offering a way to explore novel mechanisms of coherent energy exchange. Here, we have considered a resonator that starts to oscillate when electrons with fixed spin are injected from electrical contacts to a quantum dot, realising a highly-efficient single atom laser. We have shown that the common theoretical tool to describe the laser — the rotating-wave approximation — becomes insufficient, because a large…
