SUMMARY:Quantum Optics with Nuclear Transitions and X-ray Photons
UID:e6e9-a387-d34c-5759@www.laserphysik.nat.fau.de
DESCRIPTION:Narrow resonances corresponding to quantum transitions in 
 atoms\, molecules\, quantum dots\, rare-earth ions and color centers c
 onstitute the basis of quantum optics with numerous applications in se
 nsing\, imaging\, computation\, communication\, etc. The highest quali
 ty atomic resonances with Q-factor ~1015-1020 have been achieved in at
 omic clocks. Their realization requires low atomic density\, vacuum en
 vironment\, laser cooling below 100 nK temperature\, and magnetic trap
 s or optical lattices. On the other hand\, high quality resonances are
  intrinsically inherent to nuclear transitions. They do not require a 
 deep nK cooling\, are not limited to the small\, diluted ensembles and
  offer an appealing platform for nuclear clocks\, search for dark matt
 er and time variation of the fundamental constants\, gravitational and
  relativistic time dilation. However\, their investigation is challeng
 ing due to the absence of resonant coherent hard X-ray sources and eff
 icient ways to control the interaction of nuclear ensembles with X-ray
  photons. In this talk I will review some progress in this field. It i
 ncludes the experimental demonstrations of the coherent waveform shapi
 ng of the hard X-ray photons [1]\, acoustically induced transparency [
 2]\, slow light [3]\, realization of quantum nuclear memory [4\,5] and
  resonant excitation of the 12.4 keV long-lived (0.46 s) nuclear trans
 ition in 45Sc\, the most promising solid-state nuclear clock candidate
