On the finite temperature Drude weight of the anisotropic Heisenberg chain
We present a study of the Drude weightD(T ) of the spin-1/2XXZ chain in the gapless regime. The thermodynamic Bethe ansatz (TBA) is applied in two different ways. In the first application we employ the particle basis of magnons and their bound states. In this case we rederive and considerably extend earlier work in the literature. However, in the course of our investigation we find arguments th...
متن کاملFinite temperature Drude weight of an integrable Bose chain
We study the Drude weight D(T ) at finite temperatures T of an integrable bosonic model where the particles interact via nearest-neighbour coupling on a chain. At low temperatures, D(T ) is shown to be universal in the sense that this region is equivalently described by a Gaussian model. This lowtemperature limit is also relevant for the integrable one-dimensional Bose gas. We then use the ther...
متن کاملFinite-temperature dynamical density matrix renormalization group and the Drude weight of spin-1/2 chains.
We propose an easily implemented approach to study time-dependent correlation functions of one-dimensional systems at finite-temperature T using the density matrix renormalization group. The entanglement growth inherent to any time-dependent calculation is significantly reduced if the auxiliary degrees of freedom which purify the statistical operator are time evolved with the physical Hamiltoni...
متن کاملMultispinon continua at zero and finite temperature in a near-ideal Heisenberg chain.
The space-and time-dependent response of many-body quantum systems is the most informative aspect of their emergent behavior. The dynamical structure factor, experimentally measurable using neutron scattering, can map this response in wave vector and energy with great detail, allowing theories to be quantitatively tested to high accuracy. Here, we present a comparison between neutron scattering...
