Our work investigating the role of Rydberg molecules in storage and retrieval of single photons has been published in PRA:

”Electromagnetically induced transparency of ultra-long-range Rydberg molecules”
Phys. Rev. A, 96, 011402 (2017)
Very similar results had previously been observed in the MPQ Quantum Dynamics group!
