Abstract: ABSTRACT We investigate the magnetic properties of the mixed spin-1/2 and spin-1 Ising ferrimagnetic system with four-spin interaction J4 and next-nearest neighbor (NNN) coupling J′. We perform exact ground-state calculations and use the finite cluster… read more here.

DOI: 10.1088/1742-5468/acd2c5
Abstract: We study information theoretic quantities in models with three and four spin interactions. These models show distinctive characteristics compared to their nearest neighbour (NN) counterparts. Here, we quantify these in terms of the Nielsen complexity… read more here.

DOI: 10.1103/physrevb.98.235113
Abstract: We use ab initio electronic structure calculations in combination with Monte Carlo simulations to investigate the magnetic and ferroelectric properties of bulk orthorhombic HoMnO$_3$ and ErMnO$_3$. Our goals are to explain the inconsistencies in the… read more here.
