Sparse sampling and tensor network representation of two-particle Green's functions
Hiroshi Shinaoka, Dominique Geffroy, Markus Wallerberger +4
Many-body calculations at the two-particle level require a compact representation of two-particle Green's functions. In this paper, we introduce a sparse sampling scheme in the Mat…
Antiferromagnetism in RuO as -wave Pomeranchuk instability
Kyo-Hoon Ahn, Atsushi Hariki, Kwan-Woo Lee +1
We present a computational study of antiferromagnetic transition in RuO. The rutile structure with the magnetic sublattices coupled by -rotation leads to a spin-polarized…
Pressure-induced spin-state ordering in SrCoOF
Juan Fernández Afonso, Andrii Sotnikov, Atsushi Hariki +1
We study theoretically low-temperature phases of a recently synthesized compound SrCoOF under pressure. The analysis combining LDA+DMFT and a strong-coupling effective mode…
Chemical pressure effect on the optical conductivity of the nodal-line semimetals ZrSi (=S, Se, Te) and ZrGe (=S, Te)
J. Ebad-Allah, J. Fernández Afonso, M. Krottenmüller +5
ZrSiS is a nodal-line semimetal, whose electronic band structure contains a diamond-shaped line of Dirac nodes. We carried out a comparative study on the optical conductivity of Zr…
