Classical antiferromagnet on a hyperkagome lattice
John M. Hopkinson, Sergei V. Isakov, Hae-Young Kee +1
Motivated by recent experiments on Na_4Ir_3O_8 [Y. Okamoto, M. Nohara, H. Aruga-Katori, and H. Takagi, arXiv:0705.2821 (unpublished)], we study the classical antiferromagnet on a f…
A microscopic model for spiral ordering along (110) on the MnSi lattice
John M. Hopkinson, Hae-Young Kee
We study an extended Heisenberg model on the MnSi lattice. In the cubic B20 crystal structure of MnSi, Mn atoms form lattices of of corner-shared equilateral triangles. We find an…
A novel route to a finite center-of-mass momentum pairing state; current driven FFLO state
Hyeonjin Doh, Matthew Song, Hae-Young Kee
The previously studied Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state is stabilized by a magnetic field via the Zeeman coupling in spin-singlet superconductors. Here we suggest a no…
Interplay between parallel and diagonal electronic nematic phases in interacting systems
Hyeonjin Doh, Nir Friedman, Hae-Young Kee
An electronic nematic phase can be classified by a spontaneously broken discrete rotational symmetry of a host lattice. In a square lattice, there are two distinct nematic phases.…
