Magnetization process of atacamite: a case of weakly coupled sawtooth chains
L. Heinze, H. O. Jeschke, I. I. Mazin +17
We present a combined experimental and theoretical study of the mineral atacamite CuCl(OH). Density functional theory yields a Hamiltonian describing anisotropic sawtooth c…
Quantum phases of a frustrated four-leg spin tube
M. Arlego, W. Brenig, Y. Rahnavard +3
We study the ground state phase diagram of a frustrated spin-1/2 four-leg tube. Using a variety of complementary techniques, namely density matrix renormalization group, exact diag…
Transport in dimerized and frustrated spin systems
F. Heidrich-Meisner, A. Honecker, D. C. Cabra +1
We analyze the Drude weight for both spin and thermal transport of one-dimensional spin-1/2 systems by means of exact diagonalization at finite temperatures. While the Drude weight…
Giant spin canting in the S = 1/2 antiferromagnetic chain [CuPM(NO3)2(H2O)2]n observed by 13C-NMR
A. U. B. Wolter, P. Wzietek, S. Süllow +5
We present a combined experimental and theoretical study on copper pyrimidine dinitrate [CuPM(NO3)2(H2O)2]n, a one-dimensional S = 1/2 antiferromagnet with alternating local symmet…
Thermal conductivity of anisotropic and frustrated spin-1/2 chains
F. Heidrich-Meisner, A. Honecker, D. C. Cabra +1
We analyze the thermal conductivity of anisotropic and frustrated spin-1/2 chains using analytical and numerical techniques. This includes mean-field theory based on the Jordan-Wig…
Raman cross section of spin ladders
Christoph Jurecka, Verena Gruetzun, Andreas Friedrich +1
We demonstrate that a two-triplet resonance strongly renormalizes the Raman spectrum of two-leg spin ladders and moreover suggest this to be the origin of the asymmetry of the magn…
