Thermal conductivity of one-dimensional spin-1/2 systems
We analyze the thermal conductivity of frustrated spin-1/2 chains within linear-response theory focusing on its frequency dependence at finite temperatures. Using exact diagonalization, the low-frequency limit of the thermal conductivity is discussed in the high-temperature regime.
متن کاملThermal Conductivity of the S = 1/2 Quasi-One- Dimensional Ferromagnetic Spin System CsCuCl3
We have measured the thermal conductivity along the c-axis, κ∥c, parallel to ferromagnetic spin-chains of single crystals of the S = 1/2 quasi-one-dimensional spin system CsCuCl3 in magnetic fields up to 14 T, in order to investigate the thermal conductivity due to spins, κspin, and the change of thermal conductivity corresponding to the change of the spin state. In the temperature dependence o...
متن کاملDecay of spin coherences in one-dimensional spin systems
Strategies to protect multi-qubit states against decoherence are difficult to formulate because of their complex many-body dynamics. A better knowledge of the decay dynamics would help in the construction of dynamical decoupling control schemes. Here we use solid-state nuclear magnetic resonance techniques to experimentally investigate decay of coherent multi-spin states in linear spin chains. ...
متن کاملThe thermal conductivity of alternating spin chains
We study a class of integrable alternating (S1, S2) quantum spin chains with critical ground state properties. Our main results are [email protected] [email protected] [email protected] 1 the derivation of a finite set of non-linear integral equations for the thermodynamical properties of the systems and the identification of the thermal currents as conserved cu...
متن کاملThermal conductivity of spin-polarized liquid 3He.
We present the first measurements of the thermal conductivity of spin-polarized normal liquid 3He. Using the rapid melting technique to produce nuclear polarizations up to 0.7, and a vibrating wire both as a heater and a thermometer, we show that, unlike the viscosity, the conductivity increases much less than predicted for s-wave scattering. We suggest that this might be due to a small probabi...
