Abstract

The project is focused on theoretical and experimental studies of the quantum coherence effects at the atomic and nuclear transitions in solids. The main results are the following. 1. Electromagnetically Induced Transparency (EIT) and all-optical writing and probing of quantum coherence in room temperature solids are demonstrated experimentally in the first time. 2. The method for coherent suppression of excited state absorption in laser crystals is suggested. It opens the prospects for realization of the variety tunable solid state lasers including UV and VUV ranges. 3. High-efficient THz generation by means of resonant three-level mixing based on EIT in solids is predicted. 4. EIT in gamma-ray range of frequencies at the nuclear transitions via the nuclear level crossing is demonstrated experimentally in the first time. 5. Slowing of the gamma-ray photons due to the absorption line doublet is demonstrated in the first time. 6. Modifications of the Mossbauer absorption spectra under the action of laser radiation demonstrated experimentally in the first time. 7. The method for suppression of the inhomogeneous line broadening of the Mossbauer spectra is suggested.

Laser manipulation of Mossbauer transitions as a novel method of gamma-ray spectroscopy

Olga A. Kocharovskaya, Roman L. Kolesov, Yuri V. Rostovtsev +1 more

Summary form only given. Recently, it was predicted that laser radiation can be used to manipulate very efficiently nuclear transitions at gamma-ray energies in solids. It results in both drastic qualitative and strong qualitative modifications of the Mossbauer spectra under the action of coherent optical radiation. The solid sample represents a host matrix where high densities of the ions are embedded by doping. The ions should possess both Mossbauer gamma-ray and optical electronic transitions favorable for the desired effects to be observed. Basically one needs Mossbauer-active ions with strong and sharp optical lines. The latter condition is typically satisfied for rare-earth and transition-metal ions in crystalline hosts and, remarkably, the majority of them are also Mossbauer-active.

Optical control of nuclear resonant absorption: theory and experiment

Roman L. Kolesov

Modification of nuclear resonant absorption by means of laser radiation is analyzed both theoretically and experimentally. Theoretical analysis is done on the basis of four-level model of atom. This model includes both electronic and nuclear excitations. It is predicted that under coherent laser driving nuclear resonant Mossbauer absorption can be significantly modified, e.g. new Mossbauer resonances can appear, some of the existing resonances can vanish, both can be Rabi-split, broadened by laser action. In addition, it is predicted that Mossbauer absorption can be completely suppressed due to coherent population trapping. Experimental observation of laser-induced transformations of Mossbauer spectra of 57Fe2+ : MgO is accomplished. New Mossbauer lines appear with laser driving while the existing are broadened. Possible explanations of the observed changes in 57Fe2+ : MgO Mossbauer spectra are population of higher-lying electronic states of iron ion and significant modification of electronic relaxation processes due to modified Jahn-Teller interaction.

Atomic and nuclear interference phenomena and their applications

Yelena Anatolyevna Kuznetsova

In this work, interference and coherence phenomena, appearing in atomic and\nmolecular ensembles interacting with coherent light sources, as electromagnetically\ninduced transparency (EIT), coherent population trapping (CPT), and slow group\nvelocity of light are investigated. The goal of the project is to make the steps towards\nvarious applications of these phenomena, first, by studying them in solid media (which\nare the most advantageous for applications), second, by suggesting some novel applications\nsuch as CPT-based plasma diagnostics, and realization of new types of\nsolid-state lasers (based on suppression of excited-state absorption via EIT). The\nthird goal of the project is extension of coherence and interference effects well-known\nin optics to the gamma-ray range of frequencies and, correspondingly, from atomic to\nnuclear transitions. A particular technique of chirped pulse compression applied to\nM??ossbauer transitions is considered and the possibility of compression of M??ossbauer\nradiation into ultrashort gamma-ray pulses is analyzed.\nThe theoretical treatment of the interference and coherence effects is based on\nthe semiclassical description of atom-light interaction, which is sufficient for correct\nanalysis of the phenomena considered here. Coherent media are considered in two-,\nthree-, and four-level approximations while their interaction with light is studied both\nanalytically and numerically using the Maxwell-Bloch set of equations.

Coherent Control of Nuclear Excited State Population Using X-ray Free Electron Lasers

André Junker

The direct interaction between nuclei and strong electromagnetic fields generated by novel coherent x-ray light sources such as the x-ray free electron laser is studied. We investigate the case of various stable or long-lived isotopes with energetically low-lying excited states, where the laser drives the nuclear transition from the ground to the first excited state. We therefore consider the nucleus as a two-level system including the corresponding hyperfine levels in our theoretical description. The performance of present and upcoming x-ray free electron laser facilities in coherently controlling the nuclear excited state population is analyzed for setups involving both solid state as well as accelerated nuclear targets to bridge the gap between photon and transition frequency. Current and predicted laser parameters are applied to calculate excited state populations and signal photon rates of nuclei after a radiation pulse, finding significant improvements compared to former calculations. Furthermore, we determine the parameters necessary to transfer substantial amounts of the nuclear ground state population to the excited state, and therefore to bring nuclear Rabi-oscillation within reach. Additionally, we take into account for the first time collective effects that take place in solid state targets and show that they may provide a significant effect in broadening natural linewidths of nuclear levels depending on the experimental setup. Our findings support the case of nuclear quantum optics for XFEL applications. Therefore, one hopes that eventually coherent control of nuclear transitions can be successfully applied in a number of areas in nuclear physics including preparation, control and detection methods.

Suppression ofγ-photon absorption via quantum interference

Petr M. Anisimov, Farit G. Vagizov, Yuri V. Rostovtsev +2 more

We show that the interference effects (similar to electromagnetically induced transparency, which was widely studied earlier in electronic transitions in optics) may appear in γ-radiation at nuclear transitions under the condition of nuclear level anticrossing. We demonstrate it also experimentally in optically thin samples of FeCO3.
