Quasiparticles of spatially anisotropic triangular antiferromagnets in a magnetic field
Masanori Kohno
The spectral properties of the spin-1/2 Heisenberg antiferromagnet on an anisotropic triangular lattice in a magnetic field are investigated using a weak-interchain-coupling approa…
Dynamically dominant excitations of string solutions in the spin-1/2 antiferromagnetic Heisenberg chain in magnetic fields
Masanori Kohno
Using Bethe-ansatz solutions, we uncover a well-defined continuum in dynamical structure factor of the spin-1/2 antiferromagnetic Heisenberg chain in magnetic fields.…
Spinons and triplons in spatially anisotropic frustrated antiferromagnets
Masanori Kohno, Oleg A. Starykh, Leon Balents
The search for elementary excitations with fractional quantum numbers is a central challenge in modern condensed matter physics. We explore the possibility in a realistic model for…
Magnetic and Electronic Properties of the New Ferrimagnet Sr8CaRe3Cu4O24
Masanori Kohno, Xiangang Wan, Xiao Hu
Magnetic and electronic properties of the recently-discovered material Sr8CaRe3Cu4O24 were investigated by means of a quantum Monte Carlo simulation, the Green function method and…
Anomalous impurity effect on magnetization in frustrated one-dimensional ferro- and ferrimagnets
Masanori Kohno, Xiao Hu
Significant decrease of spontaneous magnetization in frustrated one-dimensional ferro- and ferrimagnets due to non-magnetic impurities is predicted. Using the density-matrix renorm…
Coexistence of a nearly spin-singlet state and antiferromagnetic long-range order in quantum spin system CuCdBO
Masashi Hase, Masanori Kohno, Hideaki Kitazawa +5
A 1/2 magnetization plateau in magnetic fields above 23 T and antiferromagnetic (AF) long-range order (AFLRO) in low fields were found in CuCdBO. Experimental results a…
