Theory of Ferromagnetism in Ca1-xLaxB6
Shuichi Murakami, Ryuichi Shindou, Naoto Nagaosa +1
Novel ferromagnetism in CaLaB is studied in terms of the Ginzburg-Landau theory for excitonic order parameters, taking into account symmetry of the wavefunctions.…
Diagrammatic Quantum Monte Carlo for Two-Body Problem: Exciton
E. A. Burovski, A. S. Mishchenko, N. V. Prokof'ev +1
We present a novel method for precise numerical solution of the irreducible two-body problem and apply it to excitons in solids. The approach is based on the Monte Carlo simulation…
Magnetic frustrations in the face centered cubic antiferromagnet NiS2
M. Matsuura, Y. Endoh, H. Hiraka +5
Neutron scattering experiment on NiS2 single crystal revealed a honeycomb pattern of the intensity distribution in reciprocal lattice space (continuous-line structure along the fcc…
Quasi-degenerate self-trapping in one-dimensional charge transfer exciton
A. S. Mishchenko, N. Nagaosa
The self-trapping by the nondiagonal particle-phonon interaction between two quasi-degenerate energy levels of excitonic system, is studied. We propose this is realized in charge t…
