Broken time-reversal symmetry in strongly correlated ladder structures
U. Schollwoeck, Sudip Chakravarty, J. O. Fjaerestad +2
We provide, for the first time, in a doped strongly correlated system (two-leg ladder), a controlled theoretical demonstration of the existence of a state in which long-range order…
LiVO(Si,Ge)O, a prototype of a two-dimensional frustrated quantum Heisenberg antiferromagnet
R. Melzi, P. Carretta, A. Lascialfari +4
NMR and magnetization measurements in LiVOSiO and LiVOGeO are reported. The analysis of the susceptibility shows that both compounds are two-dimensional Hei…
Thermodynamic properties of the one-dimensional Kondo insulators studied by the density matrix renormalization group method
N. Shibata, B. Ammon, M. Troyer +2
Thermodynamic properties of the one-dimensional Kondo lattice model at half-filling are studied by the density matrix renormalization group method applied to the quantum transfer m…
Phase diagram of depleted Heisenberg model for CaV4O9
Matthias Troyer, Hiroshi Kontani, Kazuo Ueda
We have numerically investigated the 1/5-depleted Heisenberg square lattice representing CaV4O9 using the Quantum Monte Carlo loop algorithm. We have determined the phase diagram o…
