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…
Field-induced states and thermodynamics of the frustrated Heisenberg antiferromagnet on a square lattice
Andreas Honecker, M. E. Zhitomirsky, Alexander Wietek +1
We investigate the ground-state and finite-temperature properties of the - Heisenberg antiferromagnet on the square lattice in the presence of an external magnetic field.…
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…
Anisotropic frustrated Heisenberg model on the honeycomb lattice
A. Kalz, M. Arlego, D. Cabra +2
We investigate the ground-state phase diagram of an anisotropic Heisenberg model on the honeycomb lattice with competing interactions. We use quantum Monte Carlo simulations, as we…
Order by disorder and phase transitions in a highly frustrated spin model on the triangular lattice
A. Honecker, D. C. Cabra, H. -U. Everts +2
Frustration has proved to give rise to an extremely rich phenomenology in both quantum and classical systems. The leading behavior of the system can often be described by an effect…
Resonances in a dilute gas of magnons and metamagnetism of isotropic frustrated ferromagnetic spin chains
M. Arlego, F. Heidrich-Meisner, A. Honecker +2
We show that spin-S chains with SU(2)-symmetric, ferromagnetic nearest-neighbor and frustrating antiferromagnetic next-nearest-neighbor exchange interactions exhibit metamagnetic b…
