Superconducting Spin Dynamics and Quantum Effects

Dear Colleagues,

Superconductivity and spin-related quantum phenomena represent two of the most active and promising frontiers in modern condensed matter physics. The interaction between spin and superconducting order parameters has emerged as a central theme in the pursuit of novel quantum states and functionalities. Recent developments in material synthesis, interface engineering, and quantum characterization have enabled direct observation and control of spin dynamics in superconducting systems, leading to discoveries such as spin-polarized supercurrents, spin-triplet pairing, and topological superconductivity with potential applications in quantum information technologies.

This Special Issue, “Superconducting Spin Dynamics and Quantum Effects,” is dedicated to presenting high-quality research contributions that advance the understanding of spin-dependent processes in superconducting materials and devices. It aims to provide an interdisciplinary platform for the dissemination of both theoretical and experimental studies encompassing superconducting spintronics, topological superconductivity, quantum coherence, and hybrid superconducting/magnetic heterojunctions or Josephson junctions, and superconducting quantum electrodynamics. By consolidating recent progress across materials science, condensed matter physics, and quantum engineering, this Special Issue seeks to promote cross-disciplinary collaboration and to stimulate new approaches toward the realization of spin-controlled superconducting quantum technologies.

Topics of interest include, but are not limited to, the following:

• Spin dynamics in superconductors: spin relaxation, coherence, and spin-polarized transport in superconducting interfaces, heterostructures, and Josephson junctions.
• Superconducting spintronics: spin-polarized supercurrents, spin-triplet Cooper pairs, and magnetization control through superconducting proximity effects.
• Topological and unconventional superconductivity: spin textures, Majorana quasiparticles, and nontrivial pairing symmetries.
• Quantum coherence and hybrid systems: superconducting/magnetic (ferromagnetic, antiferromagnetic, and altermagnetic, etc.) and superconducting/ semiconducting hybrid systems, superconducting cavities or superconducting quantum circuits coupling with magnon and spin-based system for qubits, entanglement, spin-based quantum manipulation, and even non-hermitian physics.
• Novel materials and heterostructures: systems exhibiting coexistence or coupling of superconductivity and magnetism, including van der Waals, oxide, and low-dimensional materials.
• Ultrafast and nonequilibrium phenomena: real-time observation of spin and charge dynamics in superconducting states and magnetic states.
• Device concepts and applications: superconducting spin valves, Josephson junctions, and quantum logic elements utilizing spin and superconducting order parameters.

By integrating perspectives from condensed matter physics, quantum materials, and device engineering, this Special Issue seeks to advance the understanding of superconducting spin dynamics and promote their application in future quantum and spintronic technologies.
