Phase transitions in the spin-1/2 Heisenberg antiferromagnet on the dimerized diamond lattice
Ronja Bärwolf, Alexander Sushchyev, Francesco Parisen Toldin +1
Using a combination of unbiased quantum Monte Carlo simulations and a decoupled dimer mean-field theory, we investigate the thermal and quantum phase transitions of the spin-1/2 He…
Thermodynamic properties of the macroscopically degenerate tetramer-dimer phase of the spin-1/2 Heisenberg model on the diamond-decorated square lattice
Katarina Karlova, Andreas Honecker, Nils Caci +3
The spin-1/2 Heisenberg antiferromagnet on the diamond-decorated square lattice in the presence of a magnetic field displays various quantum phases including the Lieb-Mattis ferrim…
Quantitative description of long-range order in the anisotropic spin-1/2 Heisenberg antiferromagnet on the square lattice
Nils Caci, Dag-Björn Hering, Matthias R. Walther +3
The quantitative description of long-range order remains a challenge in quantum many-body physics. We provide zero-temperature results from two complementary methods for the ground…
