Exploring edge states in square–octagon moiré lattice
APL PhotonicsMoiré lattices, achieved by the superposition of two or more twisted identical periodic lattices, are of interest to various fields because they provide additional degrees of freedom.

Topologically protected colloidal transport above a square magnetic lattice
New Journal of Physics, 2016 We theoretically study the motion of magnetic colloidal particles above a magnetic pattern and compare the predictions with Brownian dynamics simulations. The pattern consists of alternating square domains of positive and negative magnetization.

Nonzero spectral gap in several uniformly spin-2 and hybrid spin-1 and spin-2 AKLT models
Physical Review Research, 2021 Recently a few 2D AKLT models have been shown to be gapped, including the one on the hexagonal lattice, whose local spin magnitude is spin-3/2. Here we report the existence of a nonzero spectral gap on several nontrivial AKLT models having either solely ...

Subgrain and Cavity Development during Creep of Al‐3.85%Mg
Advanced Engineering Materials, EarlyView.Al‐3.85%Mg does form subgrains if crept at very high strains. This fact allows the unification of the creep description in two different alloys such as pure Al and Al–Mg alloys. It is classically considered that the creep mechanisms for type M (e.g., pure Al) and type A alloys (e.g., Al–Mg alloys) are different.

The Heisenberg antiferromagnet on the square-kagomé lattice
Condensed Matter Physics, 2009 We discuss the ground state, the low-lying excitations as well as high-field thermodynamics of the Heisenberg antiferromagnet on the two-dimensional square-kagomé lattice.

Dynamics and hysteresis in square lattice artificial spin ice
New Journal of Physics, 2013 Dynamical effects under geometrical frustration are considered in a model for artificial spin ice on a square lattice in two dimensions. Each island of the spin ice has a three-component Heisenberg-like dipole moment subject to shape anisotropies that ...

Advanced Engineering Materials, EarlyView.Ni‐base superalloys produced using additive manufacturing (AM) have a different response to heat treatments when compared to their conventional counterparts. Due to such unpredictability, various alloys with industrial interest are currently overlooked in most prior AM research.

Topological nematic spin liquid on the square kagome lattice
Physical Review Research, 2019 The ground state of the spin-1/2 kagome antiferromagnet remains uncertain despite decades of active research. Here we step aside from this debated question to address the ground-state nature of a related, and potentially just as rich, system made of ...

High‐Temperature Oxidation of the CrFeNi Medium‐Entropy Alloy
Advanced Engineering Materials, EarlyView.The oxidation behavior of equiatomic CrFeNi MEA is a key issue that determines this material's suitability for high‐temperature application. The understanding of long‐term behavior is even more crucial than short‐term corrosion effects. The alloy is exposed to synthetic air at 1000, 1050, and 1100 °C for 24, 100, and 1000 h and systematically compared ...
