Nematic charge-density-wave correlations in FeSe$_{1-x}$S$_{x}$

Autor: Liu, Ruixian, Zhang, Wenliang, Wei, Yuan, Tao, Zhen, Asmara, Teguh C., Strocov, Vladimir N., Schmitt, Thorsten, Lu, Xingye

The occurrence of charge-density-wave (CDW) order is a common thread in the phase diagram of cuprate high-transition-temperature ($T_c$) superconductors. In iron-based superconductors (FeSCs), nematic order and fluctuations play a decisive role in dr

We use resonant inelastic X-ray scattering (RIXS) at the Fe-L$_3$ edge to study the spin excitations of uniaxial-strained and unstrained FeSe$_{1-x}$S$_{x}$ ($0\leq x\leq0.21$) samples. The measurements on unstrained samples reveal dispersive spin ex

Novel Cu-based dz2 order at a YBa2Cu3O7/ manganite interface

Autor: Gaina, Roxana, Nicholson, Christopher W., Rumo, Maxime, Sarkar, Subhrangsu, Khmaladze, Jarji, Paris, Eugenio, Tseng, Yi, Zhang, Wenliang, Asmara, Teguh C., McNally, Daniel, Piamonteze, Cinthia, Weschke, Eugen, Schmitt, Thorsten, Monney, Claude, Bernhard, Christian

The interplay of nearly degenerate orders in quantum materials can lead to a myriad of emergent phases. A prominent case is that of the high-Tc cuprates for which the relationship between superconductivity and a short-ranged, incommensurate charge de

Large spectral weight transfer in optical conductivity of SrTiO$_{3}$ induced by intrinsic vacancies

Autor: Asmara, Teguh C., Wang, Xiao, Santoso, Iman, Zhang, Qinfang, Shirakawa, Tomonori, Qi, Dongchen, Kotlov, Aleksei, Motapothula, Mallikarjuna R., Breese, Mark H., Venkatesan, T., Yunoki, Seiji, Rübhausen, Michael, Ariando, Rusydi, Andrivo

The optical conductivity ($\sigma_{1}$) of SrTiO$_{3}$ for various vacancies has been systematically studied using a combination of ultraviolet - vacuum ultraviolet (UV-VUV) reflectivity and spectroscopic ellipsometry. For cation (Ti) vacancies, $\si
