Ensemble in phase space: statistical formalism of quantum mechanics

Chol Jong, Byong-Il Ri, Song-Guk Kim +3

We present an alternative formalism of quantum mechanics tailored to statistical ensemble in phase space. The purpose of our work is to show that it is possible to establish an alt…

First-principles study of organically modified muscovite mica with ammonium (NH $_{4}^{+}$ ) or methylammonium (CH $_{3}$ NH $_{3}^{+}$ ) ion

Chol-Jun Yu, Song-Hyok Choe, Yong-Man Jang +2

Using density functional theory calculations, we have investigated the interlayer cation exchange phenomena in muscovite mica, which is motivated by a necessity to develop flexible…

Electronic structure and photo absorption property of pseudo-cubic perovskites CH $_{3}$ NH $_{3}$ PbX $_{3}$ (X=I, Br) including van der Waals interaction

Chol-Jun Yu, Un-Gi Jong, Mun-Hyok Ri +1

Using density functional theory with the inclusion of van der Waals (vdW) interaction, we have investigated electronic energy bands, density of states, effective masses of charge c…
