Evidence for Ballistic Thermal Conduction in the One-Dimensional S=1/2 Heisenberg Antiferromagnetic Spin System Sr2CuO3

Takayuki Kawamata, Nobuo Takahashi, Tadashi Adachi +4

We have measured the thermal conductivity of the one-dimensional (1D) S=1/2 Heisenberg antiferromagnetic spin system of Sr2Cu1-xPdxO3 single crystals including nonmagnetic impuriti…

Momentum Dependent Charge Excitations of Two-Leg Ladder: Resonant Inelastic X-ray Scattering of (La,Sr,Ca)14Cu24O41

K. Ishii, K. Tsutsui, T. Tohyama +8

Momentum dependent charge excitations of a two-leg ladder are investigated by resonant inelastic x-ray scattering of (La,Sr,Ca)14Cu24O41. In contrast to the case of a square lattic…

Drastic enhancement of magnon thermal conductivity in the Bose-Einstein condensed state of TlCuCl $_{3}$

K. Kudo, M. Yamazaki, T. Kawamata +4

We have measured the thermal conductivity of a TlCuCl $_{3}$ single crystal in magnetic fields up to 14 T. It has been found that the temperature dependence of the thermal conductivit…
