About this Research Topic
The recent exciting progress in achieving superconductivity at higher temperatures and the latest advances in topological superconductivity and its applications in quantum information offer remarkable momentum to kick off this section. Through the heroic efforts of numerous scientists and engineers, the superconducting transition temperature (Tc) has continuously climbed above prior records, e.g. to 164 K in the HgBa2Ca2Cu3O8+delta cuprate under the pressure of 32 GPa in 1994 and to above 200 K in the hydrides under pressure above 150 GPa since 2015. To facilitate the application of such high-temperature superconductivity (HTS), a concentrated effort is needed to remove the extreme conditions required. Recent work by Chu et al. demonstrated such a possibility in FeSe, i.e., Tc of ~ 37 K was retained without pressure. With improved algorithms and computer power, structure-search computational schemes are becoming important aids for discovering new materials and in searching for metastable HTS states under high pressure or at ambient.
This section covers frontiers of superconductor research, including efforts to raise the superconducting transition temperature (Tc), understand the superconducting pairing mechanisms, probe the fundamental physics of quantum materials, and map the energy landscapes in attempts to quench interesting phases to ambient conditions. The hope is that this collection of articles will serve to inspire and guide future searches for novel superconductors and related materials to advance both fundamental research and applications in science and technology.
This Research Topic will contain the following themes:
- Recent breakthroughs in raising Tc using the following approaches: physical pressure, pressure quench, interfacial coupling, and advanced doping.
- Investigation of the coexistence of topology and other quantum phases, e.g., superconductivity, magnetism, charge density waves, and ferroelectricity.
- Investigation of the synthesis methods, superconducting properties, and normal-state properties of hydrides, and the search for ternary and higher-order structures of hydride material.
- Spectroscopy studies probing the fundamental physics of superconductors as quantum materials.
- Understanding of pairing mechanisms and recent theoretical predictions for high-temperature superconducting materials under high pressure.
