Phase diagram and continuous pair-unbinding transition of the bilinear-biquadratic S=1 Heisenberg chain in a magnetic field
Salvatore R. Manmana, Andreas M. Läuchli, Fabian H. L. Essler +1
We investigate the properties of the Heisenberg S=1 chain with bilinear and biquadratic interactions in a magnetic field using the Density Matrix Renormalization Group, Bethe ansat…
Dzyaloshinskii-Moriya anisotropy and non-magnetic impurities in the kagome system ZnCu_3(OH)_6Cl_2
Ioannis Rousochatzakis, Salvatore R. Manmana, Andreas M. Läuchli +2
Motivated by recent nuclear magnetic resonance experiments on ZnCu(OH)Cl, we present an exact-diagonalization study of the combined effects of non-magnetic impurities a…
Field-Controlled Magnetic Order in the Quantum Spin-Ladder System (Hpip)2CuBr4
B. Thielemann, Ch. Rüegg, K. Kiefer +18
Neutron diffraction is used to investigate the field-induced, antiferromagnetically ordered state in the two-leg spin-ladder material (Hpip)2CuBr4. This "classical" phase, a conseq…
