Abstract
Electromagnetically induced transparency is predicted for x rays in laser-dressed neon gas. The x-ray photoabsorption cross section and polarizability near the Ne edge are calculated using an ab initio theory suitable for optical strong-field problems. The laser wavelength is tuned close to the transition between and (). The minimum laser intensity required to observe electromagnetically induced transparency is of the order of . The ab initio results are discussed in terms of an exactly solvable three-level model. This work opens new opportunities for research with ultrafast x-ray sources.
