Nonlinear phononics in LaFeAsO: Optical control of the crystal structure toward possible enhancement of superconductivity
Shu Kamiyama, Tatsuya Kaneko, Kazuhiko Kuroki +1
Nonlinear phononics provides a route to control crystal structures through light-induced phonon excitation. In this study, we apply nonlinear phononics to an iron-based superconduc…
Theoretical proposal of superconductivity in hole-doped reduced bilayer nickelate La3Ni2O6: a manifestation of orbital-space bilayer model with incipient bands
Shu Kamiyama, Reo Kohno, Yuto Hoshi +4
A correspondence exists between the multi-orbital Hubbard model and the bilayer Hubbard model, in which superconductivity is optimized in an incipient-band regime in both cases. In…
Electronic band structure, phonon dispersion, and magnetic triple-q state in GdGaI
Tatsuya Kaneko, Ryota Mizuno, Shu Kamiyama +2
We theoretically investigate the physical properties of the magnetic van der Waals material GdGaI. Using first-principles calculations, we compute the phonon dispersion of GdGaI an…
Optical control of the crystal structure in the bilayer nickelate superconductor La3Ni2O7 via nonlinear phononics
Shu Kamiyama, Tatsuya Kaneko, Kazuhiko Kuroki +1
Superconductivity in the bilayer nickelate LaNiO occurs when the interlayer Ni-O-Ni bond angle becomes straight under pressure, suggesting a strong relationship between…
