Three-sublattice ordering of the SU(3) Heisenberg model of three-flavor fermions on the square and cubic lattices
Tamas A. Toth, Andreas M. Laeuchli, Frederic Mila +1
Combining a semi-classical analysis with exact diagonalizations, we show that the ground state of the SU(3) Heisenberg model on the square lattice develops three-sublattice long-ra…
Statics and dynamics of weakly coupled antiferromagnetic spin-1/2 ladders in a magnetic field
Pierre Bouillot, Corinna Kollath, Andreas M. Läuchli +9
We investigate weakly coupled spin-1/2 ladders in a magnetic field. The work is motivated by recent experiments on the compound (C5H12N)2CuBr4 (BPCB). We use a combination of numer…
Bridging frustrated-spin-chain and spin-ladder physics: quasi-one-dimensional magnetism of BiCu2PO6
Alexander A. Tsirlin, Ioannis Rousochatzakis, Deepa Kasinathan +6
We derive and investigate the microscopic model of the quantum magnet BiCu2PO6 using band structure calculations, magnetic susceptibility and high-field magnetization measurements,…
Effective spin model for the spin-liquid phase of the Hubbard model on the triangular lattice
H-Y. Yang, A. Laeuchli, F. Mila +1
We show that the spin liquid phase of the half-filled Hubbard model on the triangular lattice can be described by a pure spin model. This is based on a high-order strong coupling e…
Statistical properties of the spectrum the extended Bose-Hubbard model
Corinna Kollath, Guillaume Roux, Giulio Biroli +1
Motivated by the role that spectral properties play for the dynamical evolution of a quantum many-body system, we investigate the level spacing statistic of the extended Bose-Hubba…
Entanglement Scaling of Fractional Quantum Hall states through Geometric Deformations
Andreas Laeuchli, Emil J. Bergholtz, Masudul Haque
We present a new approach to obtaining the scaling behavior of the entanglement entropy in fractional quantum Hall states from finite-size wavefunctions. By employing the torus geo…
