Topology in Biological Piezoelectric Materials
Advanced Materials, EarlyView.This review summarizes the topological structures in biological piezoelectric materials, covering morphology evolution, spatial arrangement, and biomimetic strategies. These topologies modulate structure‐property relationships across multiple scales, enabling performance enhancement and multifunctional integration.

Simulating thermal density operators with cluster expansions and tensor networks
SciPost Physics, 2023 We provide an efficient approximation for the exponential of a local operator in quantum spin systems using tensor-network representations of a cluster expansion. We benchmark this cluster tensor network operator (cluster TNO) for one-dimensional systems,

Cluster variation method and disorder varieties of two-dimensional Ising-like models
, 2000 I show that the cluster variation method, long used as a powerful hierarchy of approximations for discrete (Ising-like) two-dimensional lattice models, yields exact results on the disorder varieties which appear when competitive interactions are put into

Low-temperature series for renormalized operators: The ferromagnetic square-lattice Ising model [PDF]
, 1994 A method for computing low-temperature series for renormalized operators in the two-dimensional Ising model is proposed. These series are applied to the study of the properties of the truncated renormalized Hamiltonians when we start at very low ...

Quantitative Electron Beam‐Single Atom Interactions Enabled by Sub‐20‐pm Precision Targeting
Advanced Science, EarlyView.Atomic lock‐on (ALO) is a rapid, low‐dose in situ technique in scanning transmission electron microscopy (STEM) that achieves sub‐20 picometer (pm) beam positioning. A sparse annular scan collects positional information while avoiding irradiation of the target site.

Crossover scaling in the two-dimensional three-state Potts model
Condensed Matter Physics, 2013 We apply simulated tempering and magnetizing (STM) Monte Carlo simulations to the two-dimensional three-state Potts model in an external magnetic field in order to investigate the crossover scaling behaviour in the temperature-field plane at the Potts ...

The critical Z-invariant Ising model via dimers: the periodic case
, 2008 We study a large class of critical two-dimensional Ising models namely critical Z-invariant Ising models on periodic graphs, example of which are the classical square, triangular and honeycomb lattice at the critical temperature.

Advanced Science, EarlyView.It is shown that anisotropic strain offers a novel approach to control the magnetic ground state in heterostructures of a Kagome antiferromagnet, unlocking new functionalities. This strain induces finite scalar spin chirality, resulting in a pronounced Berry curvature in momentum space, leading to room‐temperature anomalous Hall effect.

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 ...

Bound states in two-dimensional spin systems near the Ising limit: A quantum finite-lattice study
, 2010 We analyze the properties of low-energy bound states in the transverse-field Ising model and in the XXZ model on the square lattice. To this end, we develop an optimized implementation of perturbative continuous unitary transformations.
