Origin of the mid-infrared peaks in the optical conductivity of LaMnO
Purevdorj Munkhbaatar, Kim Myung-Whun
We calculated the infrared conductivity spectrum of orbitally ordered LaMnO in phonon frequency and overtone frequency ranges. We considered orbital exchange, Jahn-Teller elect…
An information entropy interpretation of photon absorption by dielectric media
Sung Wook Han, Kim Myung-Whun
We measured photon absorption in dielectric media and proposed the photon-version Beer-Lambert's law to quantify the absorption. We used a Hong-Ou-Mandel interferometer and 810 nm…
Spectral intensity and phase changes of short laser pulses by two-photon absorption
Tsogvoo Khos-Ochir, Kim Myung-Whun, Purevdorj Munkhbaatar
We calculated third order non-linear polarization to estimate the two-photon absorption of non-interacting two-level molecules in the transmission-type degenerate pump-probe geomet…
Anisotropic optical response of the mixed-valent Mott-Hubbard insulator NaCu2O2
Y. Matiks, A. N. Yaresko, K. Myung-Whun +4
We report the results of a comprehensive spectroscopic ellipsometry study of NaCu2O2, a compound composed of chains of edge-sharing Cu2+O4 plaquettes and planes of Cu1+ ions in a O…
Charge states and magnetic ordering in LaMnO3/SrTiO3 superlattices
Woo Seok Choi, D. W. Jeong, S. S. A. Seo +5
We investigated the magnetic and optical properties of [(LaMnO3)n/(SrTiO3)8]20 (n = 1, 2, and 8) superlattices grown by pulsed laser deposition. We found a weak ferromagnetic and s…
