Symmetry breaking and thermal phase transition of the spin-1 quantum magnet with SU(3) symmetry on the simple cubic lattice
Nils Caci, Dominik Chudy, Pablo Daniel Mendez Mariscal +2
Using a combined analysis from Poisson-Dirichlet and symmetry-breaking calculations as well as quantum Monte Carlo simulations, we examine the ordered phase and the thermal phase t…
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…
Thermodynamics of the spin-1/2 Heisenberg antiferromagnet on the star lattice
Adrien Reingruber, Nils Caci, Stefan Wessel +1
Using a combination of quantum Monte Carlo simulations in adapted cluster bases, the finite temperature Lanczos method, and an effective Hamiltonian approach, we explore the thermo…
Phases of the spin-1/2 Heisenberg antiferromagnet on the diamond-decorated square lattice in a magnetic field
Nils Caci, Katarina Karlova, Taras Verkholyak +3
The spin-1/2 Heisenberg antiferromagnet on the frustrated diamond-decorated square lattice is known to feature various zero-field ground-state phases, consisting of extended monome…
Poisson-Dirichlet distributions and weakly first-order spin-nematic phase transitions
Nils Caci, Peter Mühlbacher, Daniel Ueltschi +1
We provide a quantitative characterization of generic weakly first-order thermal phase transitions out of planar spin-nematic states in three-dimensional spin-one quantum magnets,…
