    Spectroscopic evidence for a charge-density-wave condensate in a charge-ordered manganite: Observation of collective excitation mode in Pr0.7_{\text{0.7}}Ca0.3_{\text{0.3}}MnO3_{\text{3}} by using THz time-domain spectroscopy

    THz time-domain spectroscopy was used to directly probe the low-energy (0.5--5 meV) electrodynamics of the charge-ordered manganite Pr0.7_{0.7}Ca0.3_{0.3}MnO3_3. We revealed the existence of a finite peak structure around 2--3 meV well below the charge gap ∌300\sim300 meV. In analogy to the low-energy optical properties of the well-studied low-dimensional materials, we attributed this observed structure to the collective excitation mode arising from the charge-density-wave condensate. This finding provides the importance role of the quasi-one dimensional nature of the charge and orbital ordering in Pr0.7_{0.7}Ca0.3_{0.3}MnO3_3.Comment: REVTeX4, 8 pages including 7 figures and 2 table
