Perturbative approach to quantum tunneling and quantum interferences in spin clusters
Ivo A. Maceira, Frédéric Mila, Markus Müller
Collective tunneling is a ubiquitous phenomenon in finite-size spin clusters that shows up in systems as diverse as molecular magnets or spin clusters adsorbed at surfaces. The pro…
Spin- kagome Heisenberg antiferromagnet with strong breathing anisotropy
Saeed S. Jahromi, Roman Orus, Didier Poilblanc +1
We study the zero-temperature phase diagram of the spin- Heisenberg model with breathing anisotropy (i.e., with different coupling strength on the upward and downward…
Magnetic field induced bound states in spin- ladders
Mithilesh Nayak, Dominic Blosser, Andrey Zheludev +1
Motivated by the intriguing mode splittings in a magnetic field recently observed with inelastic neutron scattering in the spin ladder compound (CHN)CuBr (BPCB),…
Generalization of the Haldane conjecture to SU() chains
Kyle Wamer, Miklós Lajkó, Frédéric Mila +1
Recently, SU(3) chains in the symmetric and self-conjugate representations have been studied using field theory techniques. For certain representations, namely rank- symmetric o…
Spinon confinement and deconfinement in spin-1 chains
Laurens Vanderstraeten, Elisabeth Wybo, Natalia Chepiga +2
Motivated by the rich phase diagrams recently unveiled in frustrated spin-1 chains with competing next-nearest neighbour and four-spin interactions, we investigate the nature of th…
Dimensional crossover in the SU(4) Heisenberg model in the six-dimensional antisymmetric self-conjugate representation revealed by quantum Monte Carlo and linear flavor-wave theory
Francisco H. Kim, Fakher F. Assaad, Karlo Penc +1
Using linear flavor-wave theory (LFWT) and auxiliary field quantum Monte Carlo (QMC), we investigate the properties of the SU(4) Heisenberg model on the anisotropic square lattice…
