Thermodynamics of the hyperkagome-lattice Heisenberg antiferromagnet
Taras Hutak, Taras Krokhmalskii, Jürgen Schnack +2
The hyperkagome-lattice Heisenberg antiferromagnet allows to study the interplay of geometrical frustration and quantum as well as thermal fluctuations in three dimensions.…

Spin-half Heisenberg antiferromagnet on a symmetric sawtooth chain: Rotation-invariant Green's functions and high-temperature series
Taras Hutak, Taras Krokhmalskii, Oleg Derzhko +1
We apply the rotation-invariant Green's function method to study the finite-temperature properties of a sawtooth-chain (also called -chain) antiferromagnetic Heisenber…
