We discovered stripe patterns of trimerization-ferroelectric domains in hexagonal REMnO 3
(RE= Ho,⋯, Lu) crystals (grown below ferroelectric transition temperatures (T c), reaching up …

Two-dimensional condensed matter is realized in increasingly diverse forms that are
accessible to experiment and of potential technological value. The properties of these …

Local master equations are a widespread tool to model open quantum systems, especially
in the context of many-body systems. These equations, however, are believed to lead to …

A new “bond-algebraic” approach to duality transformations provides a very powerful
technique to analyze elementary excitations in the classical two-dimensional XY and p-clock …

We perform the state-of-the-art tensor network simulations directly in the thermodynamic limit
to clarify the critical properties of the q-state clock model on the square lattice. We determine …

We study the effect of spatial anisotropy on polar flocks by investigating active q-state clock
models in two dimensions. In contrast to the equilibrium case, we find that any amount of …

We demonstrate that a machine learning technique with a simple feedforward neural
network can sensitively detect two successive phase transitions associated with the …

We study q-state clock models of regular and Villain types with using cluster-spin updates
and observed double transitions in each model. We calculate the correlation ratio and size …

In this paper, a modified method of anomaly detection using convolutional autoencoders is
employed to predict phase transitions in several statistical mechanical models on a square …

We present the results of finite-temperature classical Monte Carlo simulations of a strongly
spin-orbit-coupled nearest-neighbor triangular-lattice model for the candidate U (1) quantum …
