Critical properties of the S=1 spin dimer compound Ba3Mn2O8
S. Suh, K. A. Al-Hassanieh, E. C. Samulon +8
Ba3Mn2O8 is a hexagonally coordinated Mn5+ S=1 spin dimer system with small uniaxial single-ion anisotropy. 135,137Ba NMR spectroscopy is used to establish the lower critical field…
Asymmetric quintuplet condensation in the frustrated S=1 spin dimer compound Ba3Mn2O8
E. C. Samulon, Y. Kohama, R. D. McDonald +5
Ba3Mn2O8 is a spin-dimer compound based on pairs of S = 1, 3d2, Mn5+ ions arranged on a triangular lattice. Antiferromagnetic intradimer exchange leads to a singlet ground state in…
Excitons in the One-Dimensional Hubbard Model: a Real-Time Study
K. A. Al-Hassanieh, F. A. Reboredo, A. E. Feiguin +2
We study the real-time dynamics of a pair hole/doubly-occupied-site, namely a holon and a doublon, in a 1D Hubbard insulator with on-site and nearest-neighbor Coulomb repulsion. Ou…
Hyperfine interaction induced decoherence of electron spins in quantum dots
Wenxian Zhang, V. V. Dobrovitski, K. A. Al-Hassanieh +2
We investigate in detail, using both analytical and numerical tools, the decoherence of electron spins in quantum dots (QDs) coupled to a bath of nuclear spins in magnetic fields o…
Spatially anisotropic Heisenberg Kagome antiferromagnet
W. Apel, T. Yavors'kii, H. -U. Everts
In the search for spin-1/2 kagome antiferromagnets, the mineral volborthite has recently been the subject of experimental studies [Hiroi et al.,2001]. It has been suggested that th…
Applying Adaptive Time-Dependent DMRG to Calculate the Conductance of Strongly Correlated Nanostructures
K. A. Al-Hassanieh, A. E. Feiguin, J. A. Riera +2
A procedure based on the recently developed ``adaptive'' time-dependent density-matrix-renormalization-group (DMRG) technique is presented to calculate the zero temperature conduct…
