Atomic and Nuclear Interference Phenomena in Solids

该实验研究计划的重点是将原子干涉领域扩展到两个重要方向：（i）从气体到固体介质和（ii）从原子到核跃迁。该计划的具体目标包括对以下现象进行首次实验演示和相关的理论研究：1）λ和双λ方案中的电磁感应透明性以及室温下固体中的有效四波混频。 2)在从激发的布居能态到连续态的跃迁处使用脉冲串形式的泵浦来抑制激发态吸收，该脉冲串为自身提供电磁感应透明（EIT）。3)激光辐射对时间分辨同步辐射光谱的影响。4)激光辐射对原子核和电子自旋的磁偶极-偶极相互作用引起的穆斯堡尔谱的影响。5)通过符合技术的核干扰效应。6)激光辐射引起的γ射线跃迁的EIT。该计划的更广泛影响涉及学生培训。

This experimental research program is focused on extending the field of atomic interference into two important directions: (i) from gaseous to solid media and (ii) from atomic to the nuclear transitions. The specific objectives pursued within the program include working toward the first experimental demonstrations, and associated theoretical studies, of the following phenomena: 1) Electromagnetically induced transparency in the lambda and double lambda schemes and efficient four-wave mixing at room temperature in a solid. 2) Suppression of excited state absorption at the transition from an excited populated energy state to the continuum of states using pumping in the form of a pulse train that provides Electromagnetically Induced Transparency (EIT) for itself. 3) Influence of laser radiation on the time-resolved synchrotron radiation spectra. 4) Effects of laser radiation on the Mossbauer spectra caused by magnetic dipole-dipole interaction of the nuclear and electronic spins. 5) Nuclear interference effects via the coincidence technique. 6) EIT at gamma-ray transitions induced by laser radiation. The broader impact of the program involves student training.
