Approaching Kasteleyn transition in frustrated quantum Heisenberg antiferromagnets
Katarina Karlova, Afonso Rufino, Taras Verkholyak +5
We show that the Kasteleyn transition, the abrupt proliferation of infinite strings of defects in classical dimer and related models, can also be relevant for frustrated 2d quantum…
Boundary operator product expansion coefficients of the three-dimensional Ising universality class
Dorian Przetakiewicz, Stefan Wessel, Francesco Parisen Toldin
Recent advances in conformal field theory and critical phenomena have focused on the characterization of boundary or defects in a conformally invariant system. In this Letter we st…
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…
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…
