In the standard BCS theory of superconductivity, the Cooper pairs are formed by electrons from the same band. However, pairing of electrons from different bands may play an important role in many superconducting materials of current interest. Including interband pairing alongside the usual intraband one leads to qualitative changes in the nodal structure: energy gap nodes can (dis)appear,...
There are increasing interests in topological phenomena in quasicrystals (QCs), which possess long-range order without periodicity. Superconductivity has been discovered experimentally in QCs [1], and some theoretical works have shown that topological superconductivity can emerge in two-dimensional QCs such as Ammann-Beenker (AB) QCs [2]. However, there is no fundamental difference in the...
Semiconductor random access memory (RAM) is a fast, volatile memory used by computers to store data. In the early 2000s, it was demonstrated that magnetic moments can be manipulated using electric currents, enabling the development of magnetic RAM (MRAM) that matches the speed of semiconductor RAM while also being non-volatile—that is, capable of retaining data even when power is turned off....
Although superconducting qubits have seen improvements in coherence times over the last decades, their performance remains orders of magnitude below that needed for a fully realizable quantum computer. A major limitation is driven by large populations of non-equilibrium quasiparticles in the qubits which can induce decoherence. These quasiparticles may originate when ionizing radiation, either...
