Spin-Triplet Superconductivity Induced by All-In-All-Out Spin Fluctuation in Pyrochlore Electronic System
Akiho Sumiyoshiya, Tetsuya Takimoto
We study the symmetry of superconductivity around the All-In-All-Out (AIAO) spin ordered phase in a nearly half-filled pyrochlore electronic system. The electronic system is descri…
Charge order induced in an orbital density-wave state
Dheeraj Kumar Singh, Tetsuya Takimoto
Motivated by the recent ARPES measurements (Evtushinsky et. al., PRL {\bf 105}, 147201 (2010)) and evidence for the density-wave state for the charge and orbital ordering (García e…
On the origin of CE-type orbital fluctuations in the ferromagnetic metallic LaSrMnO
Dheeraj Kumar Singh, Ki Hoon Lee, Tetsuya Takimoto
We investigate the orbital fluctuations in the ferromagnetic-metallic phase of LaSrMnO by considering a two orbital model within a tight-binding description…
Orbital ordering transition in the single-layer manganites near half doping: a weak-coupling approach
Dheeraj Kumar Singh, Tetsuya Takimoto
The roles of crystal-field splitting and Jahn-Teller distortions on the orbital ordering transition are investigated in the single-layer manganites near half doping. Crystal-field…
Derivation of the superconducting gap equation for the noncentrosymmetric superconductor Li2Pt3B
Soumya P. Mukherjee, Tetsuya Takimoto
We present here the mathematical background of our approach, presented in Phys. Rev. B 86, 134526 (2012) regarding the gap function and symmetry for the noncentrosymmetric (NCS) su…
Low-energy Spin Excitation in Coexistent Phase of Antiferromagnetism and d-wave Superconductivity
Hyun-Jung Lee, Tetsuya Takimoto
Nuclear quadrupole resonance measurements have shown evidences that the heavy fermion compound CeRhIn exhibits a coexistent phase with commensurate antiferromagnetism and d-wav…
