论文摘要
巨型压力对于对凝结物理学和地球物理的尖端研究至关重要。随着钻石砧细胞的发展，数十年来，对高压的实验室研究已经进入了兆巴时代。但是，在超高压力下实施原位磁性感应仍然具有挑战性。在这里，我们证明了钻石氮 - 牙（NV）中心的光学检测到的磁共振，这是一种有希望的应变和磁场的量子传感器，高达1.4 mbar。我们量化了高压下NV荧光的还原和蓝光。我们证明了NV电子旋转的连贯操作，并将其工作压力延伸到Megabar区域。这些结果为我们对钻石NV中心的理解提供了新的启示，并将在极端条件下受益。
Megabar pressures are of crucial importance for cutting-edge studies of condensed matter physics and geophysics. With the development of diamond anvil cell, laboratory studies of high pressure have entered the megabar era for decades. However, it is still challenging to implement in-situ magnetic sensing under ultrahigh pressures. Here, we demonstrate optically detected magnetic resonance of diamond nitrogen-vacancy (NV) centers, a promising quantum sensor of strain and magnetic fields, up to 1.4 Mbar. We quantify the reduction and blueshifts of NV fluorescence under high pressures. We demonstrate coherent manipulation of NV electron spins and extend its working pressure to the megabar region. These results shed new light on our understanding of diamond NV centers and will benefit quantum sensing under extreme conditions.
