“…Therefore, Tm 2 O 3 reveals two sets of CF excitations, one for each Wyckoff position. The CF scheme connected with a 24d position was investigated in detail in the case of Tm-doped nonmagnetic Y 2 O 3 [44]. The first observed excitation in our spectra, the pronounced excitation at approximately 3.8 meV, is identified to be the first CF excitation of the 24d site scheme.…”

“…Trials to fit the magnetic excitations of Tm 2 O 3 in the measured spectra failed, mainly due to a large number of CF parameters and only a few related (sufficiently intensive) peaks in the spectra. Nevertheless, we calculated the spectrum related to the 24d site from known CF parameters [44]. The calculation showed that the intensity of excitations significantly decreases, coming from low to high energies.…”

The newly synthesized Tm 2 Ir 2 O 7 iridate is investigated using neutron scattering techniques. Powder neutron diffraction patterns confirm that Tm 2 Ir 2 O 7 crystallizes in a cubic structure of pyrochlore type, consistent with the rest of the rare-earth A 2 Ir 2 O 7 series, and the crystal structure is preserved down to 0.2 K. The thermal expansion of the crystal lattice is well described by a Debye model of lattice vibrations. A weak magnetic signal consistent with the so-called all-in-all-out magnetic order (AIAO) is traced at low temperature; however, it cannot serve as unambiguous evidence of the AIAO structure in the compound. Nondispersive magnetic excitations in energy-momentum space are observed in inelastic neutron scattering spectra of Tm 2 Ir 2 O 7 . The crystal-field scheme and parameters of the thulium iridate are refined and discussed with respect to the specific heat and magnetization data. The results are supported by mean-field calculations.

“…The whole question is how to silence the primary 2PE and to preserve the integrity of the captured information until the emission of the secondary echo. Longdell [24,25] proposed to kill the primary echo by Stark-effect-induced interference [26,27]. We here propose to rely on spatial phase mismatching, which eliminates the need for an external field.…”

Revival of silenced echo and quantum memory for light

et al. 2011

We propose an original quantum memory protocol. It belongs to the class of rephasing processes and is closely related to two-pulse photon echo. It is known that the strong population inversion produced by the rephasing pulse prevents the plain two-pulse photon echo from serving as a quantum memory scheme. Indeed gain and spontaneous emission generate prohibitive noise. A second π-pulse can be used to simultaneously reverse the atomic phase and bring the atoms back into the ground state. Then a secondary echo is radiated from a non-inverted medium, avoiding contamination by gain and spontaneous emission noise. However, one must kill the primary echo, in order to preserve all the information for the secondary signal. In the present work, spatial phase mismatching is used to silence the standard two-pulse echo. An experimental demonstration is presented.

In this chapter, we will describe the storage and retrieval of quantum light (heralded single photons and entangled photons) in atomic ensembles in a solid state environment. We will consider ensembles of rare-earth ions embedded in dielectric crystals. We will describe the methods used to create quantum light spectrally compatible with the narrow atomic transitions, as well as possible protocols based on dipole rephasing that can be used to reversibly map the quantum light onto collective atomic excitations. We will review the experimental state of the art and describe in more detail quantum light storage experiments in neodymium and praseodymium doped crystals.
