Translational-Symmetry-Broken Magnetization Plateaux of the Anisotropic Antiferromagnetic Chain
Tomohide Kawatsu, Haruto Suzuki, Masaru Hashimoto +6
The magnetization process of the quantum spin chain with the anisotropy and the single-ion anisotropy is investigated using the numerical diagonalization of finit…
X-ray free-electron laser observation of giant and anisotropic magnetostriction in -O at 110 Tesla
Akihiko Ikeda, Yuya Kubota, Yuto Ishii +18
In strong magnetic fields beyond 100 T, the significant Zeeman energy competes with the lattice interactions, where a considerable magnetostriction is expected. However, the micros…
Entanglement in the pseudogap regime of cuprate superconductors
Frederic Bippus, Juraj Krsnik, Motoharu Kitatani +4
We find a strongly enhanced entanglement within the pseudogap regime of the Hubbard model. This entanglement is estimated from the quantum Fisher information and, avoiding the ill-…
Out-of-phase Plasmon Excitations in the Trilayer Cuprate BiSrCaCuO
S. Nakata, M. Bejas, J. Okamoto +14
Within a homologous series of cuprate superconductors, variations in the stacking of CuO layers influence the collective charge dynamics through the long-range Coulomb interact…
Superconducting phase diagram of finite-layer nickelates NdNiO
Andreas Hausoel, Simone Di Cataldo, Motoharu Kitatani +2
Following the successful prediction of the superconducting phase diagram for infinite-layer nickelates, here we calculate the superconducting vs. the number of lay…
Photo-induced phase transition on black samarium monosulfide
Hiroshi Watanabe, Yusuke Takeno, Yusuke Negoro +14
To investigate the role of the excitons for the origin of the pressure-induced phase transition (BGT) from the black-colored insulator (BI) to the golden-yellow-colored metal (GM)…
