Finite 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 کاملOn 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 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 کاملFinite Temperature Models of Bose-Einstein condensation
The theoretical description of trapped weakly-interacting Bose-Einstein condensates is characterized by a large number of seemingly very different approaches which have been developed over the course of time by researchers with very distinct backgrounds. Newcomers to this field, experimentalists and young researchers all face a considerable challenge in navigating through the ‘maze’ of abundant...
متن کاملSolitons for nearly integrable bright spinor Bose-Einstein condensate
Using the explicit forms of eigenstates for linearized operator related to a matrix version of Nonlinear Schrödinger equation, soliton perturbation theory is developed for the $F=1$ bright spinor Bose-Einstein condensates. A small disturbance of the integrability condition can be considered as a small correction to the integrable equation. By choosing appropriate perturbation, the soli...
