Spin and Orbital Characters of Excitations in Iron Arsenide Superconductors Revealed by Simulated Fe L-Edge RIXS
E. Kaneshita, K. Tsutsui, T. Tohyama
We theoretically examine the orbital excitations coupled to the spin degree of freedom in the parent state of the iron-arsenide superconductor, based on the calculation in a five-b…
Pressure-induced phase transition to a novel spin state in striped nickelates
E. Kaneshita, A. R. Bishop
We analyze pressure effects on stripe states within a selfconsistent Hartree-Fock calculation for a model of a striped nickelates. The results show a transition induced by high pre…
Commensurate-incommensurate transition and associated collective modes in the stripe state of cuprates near 1/8 hole-doping
E. Kaneshita, I. Martin, A. R. Bishop
We analyze the anomalous behavior in hole-doped cuprates near 1/8 doping in terms of the commensurate-incommensurate transition of a stripe phase. Based on an effective Ginzburg-La…
Pressure-induced phase transition and bi-polaronic sliding in a hole-doped Cu_2O_3 ladder system
E. Kaneshita, I. Martin, A. R. Bishop
We study a hole-doped two-leg ladder system including metal ions, oxygen, and electron-lattice interaction, as a model for Sr_{14-x}Ca_xCu_{24}O_{41-δ}. Single- and bi-polaronic st…
Local edge modes in doped cuprates with checkerboard polaronic heterogeneity
Eiji Kaneshita, Ivar Martin, Alan R. Bishop
We study a periodic polaronic system, which exhibits a nanoscale superlattice structure, as a model for hole-doped cuprates with checkerboard-like heterogeneity, as has been observ…
Vibrational edge modes in intrinsically heterogeneous doped transition metal oxides
I. Martin, E. Kaneshita, R. J. McQueeney +2
By applying an unrestricted Hartree-Fock and a Random Phase approximations to a multiband Peierls-Hubbard Hamiltonian, we study the phonon mode structure in models of transition me…
