Low-temperature thermodynamics of the two-leg ladder Ising model with trimer rungs: A mystery explained
Taras Hutak, Taras Krokhmalskii, Onofre Rojas +2
Recently, a surprising low-temperature behavior has been revealed in a two-leg ladder Ising model with trimer rungs (Weiguo Yin, arXiv:2006.08921). Motivated by these findings, we…

Adapting Planck's route to investigate the thermodynamics of the spin-half pyrochlore Heisenberg antiferromagnet
Oleg Derzhko, Taras Hutak, Taras Krokhmalskii +2
The spin-half pyrochlore Heisenberg antiferromagnet (PHAF) is one of the most challenging problems in the field of highly frustrated quantum magnetism. Stimulated by the seminal pa…

The spin- Heisenberg ferromagnet on the pyrochlore lattice: A Green's function study
T. Hutak, P. Müller, J. Richter +2
We consider the pyrochlore-lattice quantum Heisenberg ferromagnet and discuss the properties of this spin model at arbitrary temperatures. To this end, we use the Green's function…
