Anisotropic electron damping and energy gap in BiSrCaCuO
Jiemin Li, Yanhong Gu, Takemi Yamada +9
The many body electron-electron interaction in cuprates causes the broadening of the electronic bands in \textit{\textbf{k}}-space, leading to a deviation from the standard Fermi l…
Topotactic Reduction-Driven Crystal Field Excitations in Brownmillerite Manganite Thin Films
Feng Jin, Shiyu Fan, Mingqiang Gu +12
Topotactic reduction of perovskite oxides offers a powerful approach for discovering novel phenomena, such as superconducting infinite-layer nickelates and polar metallicity, and i…
Spin-forbidden excitations in the magneto-optical spectra of CrI tuned by covalency
Connor A. Occhialini, Luca Nessi, Luiz G. P. Martins +10
Spin-forbidden () multiplet excitations and their coupling to magnetic properties are of increasing importance for magneto-optical studies of correlated materials. Nonet…
Beyond-Hubbard pairing in a cuprate ladder
Hari Padma, Jinu Thomas, Sophia TenHuisen +13
The Hubbard model is believed to capture the essential physics of cuprate superconductors. However, recent theoretical studies suggest that it fails to reproduce a robust and homog…
Dispersive dark excitons in van der Waals ferromagnet CrI3
W. He, J. Sears, F. Barantani +11
Spin-flip dark excitons are optical-dipole-forbidden quasiparticles with remarkable potential in optoelectronics, especially when they are realized within cleavable van der Waals m…
Magnetic excitations and absence of charge order in the van der Waals ferromagnet FeGeTe
V. K. Bhartiya, T. Kim, J. Li +12
Understanding the ground state of van der Waals (vdW) magnets is crucial for designing devices leveraging these platforms. Here, we investigate the magnetic excitations and charge…
