论文摘要
在环境条件下达到超导性是最大的科学梦之一。在过去几年中,高压的发现将基于氢的化合物作为使其成真的最佳候选者。正如最近的历史所示,预计在未来几年,第一原理计算将继续指导正确的轨道实验任务。考虑到离子量子波动在很大程度上影响了超导氢化物的结构和振动特性,在许多情况下,在许多情况下,它们在压力的稳定下远低于预期,至关重要的是对未来的从头开始预测产生这种影响至关重要。即使在环境压力下,低压高临界化合物的前景也是敞开的。
Reaching superconductivity at ambient conditions is one of the biggest scientific dreams. The discoveries in the last few years at high pressures place hydrogen-based compounds as the best candidates for making it true. As the recent history shows, first-principles calculations are expected to continue guiding the experimental quest in the right track in the coming years. Considering that ionic quantum fluctuations largely affect the structural and vibrational properties of superconducting hydrides, in many cases making them stable at much lower pressures than expected, it will be crucial to include such effects on the future ab initio predictions. The prospects for low-pressure high critical-temperature compounds are wide open, even at ambient pressure.
