Two-dimensional arrays of interacting magnetic nanostructures offer a remarkable
playground for simulating, experimentally, lattice spin models. Initially designed to capture …

Since the discovery of liquid crystals one hundred years ago, reentrant phase transitions
have transformed from being isolated curiosities to an established phenomenon. A …

This paper studies some properties and implications of higher-order mutual information
functions, which should serve for the analysis of general complex systems. We note that the …

The article provides a tutorial review on how to treat Ising models within mean-field (MF),
effective-field (EF) and exact methods. MF solutions of the spin-1 Blume-Capel (BC) model …

The microscopic conditions for the emergence of nonreciprocal magnon excitations in
noncentrosymmetric magnets are theoretically investigated. We show that asymmetric …

We have investigated the low-temperature thermodynamic properties of the classical dipolar
kagome Ising antiferromagnet using Monte Carlo simulations, in the quest for the ground …

Fractionalization is a ubiquitous phenomenon in topological states of matter. In this work, we
study the collective behavior of fractionalized topological charges and their instabilities …

In some spin systems with competitive inter-actions, the ordering is extremely suppressed
due to global degeneracy of the ground state. This is the spin frustration. Additional …

The exact phase diagram of an anisotropic centered honeycomb Ising lattice is obtained by
transforming the system into a 32-vertex model that satisfies the free-fermion condition. We …

Reentrance, the return of a system from an ordered phase to a previously encountered less-
ordered one as a controlled parameter is continuously varied, is a recurring theme found in …
