论文摘要
我们指出，单个准颗粒设备的功率测量为检测暗物质（DM）开辟了新的途径。这些设备的阈值是由库珀对结合能设定的，因此它们很低，以至于它们可以检测到来自银河系光环的MEV接收到的DM，以及低速度热的DM分量可能存在于地球中。使用这些新设备的现有功率测量以及使用SuperCDMS-CPD的功率测量值，我们将DM质量的独立于旋转的DM散射横截面上的新约束从约10 MEV到10 GEV设置。我们概述了未来的方向，以提高使用量子设备中的功率沉积在地球中对光晕DM和地球中热的DM种群的敏感性。
We point out that power measurements of single quasiparticle devices open a new avenue to detect dark matter (DM). The threshold of these devices is set by the Cooper pair binding energy, and is therefore so low that they can detect DM as light as about an MeV incoming from the Galactic halo, as well as the low-velocity thermalized DM component potentially present in the Earth. Using existing power measurements with these new devices, as well as power measurements with SuperCDMS-CPD, we set new constraints on the spin-independent DM scattering cross section for DM masses from about 10 MeV to 10 GeV. We outline future directions to improve sensitivity to both halo DM and a thermalized DM population in the Earth using power deposition in quantum devices.
