    "abstract": "In a recent paper [Gorshkov et al., Phys. Rev. Lett. 98, 123601 (2007)], we\npresented a universal physical picture for describing a wide range of\ntechniques for storage and retrieval of photon wave packets in Lambda-type\natomic media in free space, including the adiabatic reduction of the photon\ngroup velocity, pulse-propagation control via off-resonant Raman techniques,\nand photon-echo based techniques. This universal picture produced an optimal\ncontrol strategy for photon storage and retrieval applicable to all approaches\nand yielded identical maximum efficiencies for all of them. In the present\npaper, we present the full details of this analysis as well some of its\nextensions, including the discussion of the effects of non-degeneracy of the\ntwo lower levels of the Lambda system. The analysis in the present paper is\nbased on the intuition obtained from the study of photon storage in the cavity\nmodel in the preceding paper [Gorshkov et al., Phys. Rev. A 76, 033804 (2007)].",
