Staggered ordered phases in the three-orbital Hubbard model
Kosuke Ishigaki, Joji Nasu, Akihisa Koga +2
We study ordered phases with broken translational symmetry in the half-filled three-orbital Hubbard model with antiferromagnetic Hund coupling by means of dynamical mean-field theo…
Odd-Frequency Pairs in Chiral Symmetric Systems: Spectral Bulk-Boundary Correspondence and Topological Criticality
Shun Tamura, Shintaro Hoshino, Yukio Tanaka
Odd-frequency Cooper pairs with chiral symmetry emerging at the edges of topological superconductors are a useful physical quantity for characterizing the topological properties of…
Deformation of the Magnetic Skyrmion Lattice in MnSi under Electric Current Flow
D. Okuyama, M. Bleuel, J. S. White +17
Using small-angle neutron scattering (SANS), we investigate the deformation of the magnetic skyrmion lattice in bulk single-crystalline MnSi under electric current flow. A signific…
Spontaneously orbital-selective superconductivity in a three-orbital Hubbard model
Kosuke Ishigaki, Joji Nasu, Akihisa Koga +2
We study a three-orbital Hubbard model with negative Hund coupling in infinite dimensions, combining dynamical mean-field theory with continuous time quantum Monte Carlo simulation…
Nonreciprocal charge transport in two-dimensional noncentrosymmetric superconductors
Shintaro Hoshino, Ryohei Wakatsuki, Keita Hamamoto +1
Nonreciprocal charge transport phenomena are studied theoretically for two-dimensional noncentrosymmetric superconductors under an external magnetic field . Rashba superconducto…
Spin freezing and the Sachdev-Ye model
Philipp Werner, Aaram Kim, Shintaro Hoshino
Spin-freezing is the origin of bad-metal physics and non-Fermi liquid (non-FL) properties in a broad range of correlated compounds. In a multi-orbital lattice system with Hund coup…
