Decay of currents for strong interactions
Robin Steinigeweg
The decay of current autocorrelation functions is investigated for quantum systems featuring strong 'interactions'. Here, the term interaction refers to that part of the Hamiltonia…
Transport in the 3-dimensional Anderson model: an analysis of the dynamics on scales below the localization length
Robin Steinigeweg, Hendrik Niemeyer, Jochen Gemmer
Single-particle transport in disordered potentials is investigated on scales below the localization length. The dynamics on those scales is concretely analyzed for the 3-dimensiona…
Projection operator approach to spin diffusion in the anisotropic Heisenberg chain at high temperatures
Robin Steinigeweg, Roman Schnalle
We investigate spin transport in the anisotropic Heisenberg chain in the limit of high temperatures (β \to 0). We particularly focus on diffusion and the quantitative evaluation of…
Magnetoelastic and structural properties of azurite Cu3(CO3)2(OH)2 from neutron scattering and muon spin rotation
M. C. R. Gibson, K. C. Rule, A. U. B. Wolter +12
Azurite, Cu3(CO3)2(OH)2, has been considered an ideal example of a one-dimensional (1D) diamond chain antiferromagnet. Early studies of this material imply the presence of an order…
Nature of the spin dynamics and 1/3 magnetization plateau in azurite
K. C. Rule, A. U. B. Wolter, S. Süllow +6
We present a specific heat and inelastic neutron scattering study in magnetic fields up into the 1/3 magnetization plateau phase of the diamond chain compound azurite Cu(CO…
Strong disorder fixed points in the two-dimensional random-bond Ising model
Marco Picco, Andreas Honecker, Pierre Pujol
The random-bond Ising model on the square lattice has several disordered critical points, depending on the probability distribution of the bonds. There are a finite-temperature mul…
