2023年1月30日 · Every molecule has a point group associated with it, which are assigned by a set for rules (explained by Group theory). The character tables takes the point group and …

2020年7月16日 · Critical fluctuations of the excitonic order parameter give rise to quasi-elastic scattering of B2g symmetry, whose intensity grows inversely with temperature toward the …

Raman response function for B2g and B1g symmetry channels (1.9 eV excitation) at temperatures between 35 and 320 K. Sketches for the Fermi surface are based on ARPES data [4,5,11]. …

Symmetry species of translations, rotations, and vibrations can be determined by considering the character of the representation spanned by Cartesian vectors localized on each atom. For …

Fig. 2 we show Raman susceptibility χ (ω) at representative temperatures and dopings for the A 1g , B 2g , and B 1g symmetry channels to point out important features in relation to the ...

1993年3月15日 · Nuclear site symmetry analysis predicts six Raman-active bands. Five peaks are consistently observed, whereas the sixth remains controversial. Also, two different sets of …

2021年12月24日 · We present a comprehensive study of temperature-dependent polarized Raman scattering in a nearly stoichiometric orthorhombic YTiO3 single crystal. The lattice …

2015年4月20日 · We use the symmetry constrained low energy effective Hamiltonian of iron based superconductors to study the Raman scattering in the normal state of underdoped iron …

ken mirror symmetry to B1g, B2g, and A2g. Building on this symmetry analysis, we propose a general Ginzburg-Landau theory and connect the various nematic orders with the under-lying …

1989年5月1日 · We report the first Raman scattering measurement of the rutile structure compound IrO 2. The four allowed first-order Raman active phonon modes have been …
