Field-induced superconductivity mediated by odd-parity multipole fluctuation
Kosuke Nogaki, Youichi Yanase
Field-induced superconductivity has long presented a counterintuitive phenomenon and a pivotal challenge in condensed matter physics. In this Letter, we introduce a mechanism for a…
Correlation-induced Fermi surface evolution and topological crystalline superconductivity in CeRh2As2
Jun Ishizuka, Kosuke Nogaki, Manfred Sigrist +1
Locally noncentrosymmetric structures in crystals are attracting much attention owing to emergent phenomena associated with the sublattice degree of freedom. The newly discovered h…
Coexistence of near-EF flat band and van Hove singularity in a two-phase superconductor
Xuezhi Chen, Le Wang, Jun Ishizuka +9
In quantum many-body systems, particularly, the ones with large near-EF density states, like flat bands or van Hove singularity (VHS), electron correlations often give rise to rich…
Magnetism and superconductivity in mixed-dimensional periodic Anderson model for UTe
Ryuji Hakuno, Kosuke Nogaki, Youichi Yanase
UTe is a strong candidate for a topological spin-triplet superconductor, and it is considered that the interplay of magnetic fluctuation and superconductivity is essential fo…
Bosonic Nevanlinna Analytic Continuation
Kosuke Nogaki, Hiroshi Shinaoka
Analytical continuation (AC) connects theoretical calculations and experimentally measurable quantities. The recently proposed Nevanlinna AC method is capable of accurately reprodu…
Nevanlinna.jl: A Julia implementation of Nevanlinna analytic continuation
Kosuke Nogaki, Jiani Fei, Emanuel Gull +1
We introduce a Julia implementation of the recently proposed Nevanlinna analytic continuation method. The method is based on Nevanlinna interpolants and, by construction, preserves…
