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.…
One-dimensionally confined ammonia molecules: A theoretical study
Maksym Druchok, Volodymyr Krasnov, Taras Krokhmalskii +1
We examine a single-file chain of ammonia molecules in a carbon nanotube. To this end, we use i) molecular dynamics simulations (combined with the charges for ammonia nitrogen and…
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…
Towards a quasiphase transition in the single-file chain of water molecules: Simple lattice model
Maksym Druchok, Volodymyr Krasnov, Taras Krokhmalskii +4
Recently, X.Ma et al. [Phys. Rev. Lett. 118, 027402 (2017)] have suggested that water molecules encapsulated in (6,5) single-wall carbon nanotube experience a temperature-induced q…
