On the failure of effective-field theory in predicting a spurious spontaneous ordering and phase transition of Ising nanoparticles, nanoislands, nanotubes and nanowires
Jozef Strecka, Katarina Karlova, Olesia Krupnitska
The present work clarifies a failure of the effective-field theory in predicting a false spontaneous long-range order and phase transition of Ising nanoparticles, nanoislands, nano…

Frustrated quantum Heisenberg double-tetrahedral and octahedral chains at high magnetic fields
Olesia Krupnitska
We consider the spin-1/2 antiferromagnetic Heisenberg model on two one-dimensional frustrated lattices, double-tetrahedral chain and octahedral chain, with almost dispersionless (f…

Thermodynamic properties of BaCoSiOCl in strong magnetic field: Realization of flat-band physics in a highly frustrated quantum magnet
Johannes Richter, Olesia Krupnitska, Vasyl Baliha +2
The search for flat-band solid-state realizations is a crucial issue to verify or to challenge theoretical predictions for quantum many-body flat-band systems. For frustrated quant…
