Trions as Fundamental Species in Chemically Doped Polymer Semiconductors
Advanced Materials, EarlyView.This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

Multiplicity of periodic solutions in bistable equations [PDF]
, 2006 We study the number of periodic solutions in two first-order non-autonomous differential equations, both of which have been used to describe, among other things, the mean magnetization of an Ising magnet in a time-varying external magnetic field.

Even-number spin correlations on two-dimensional Ising lattice structures
, 2002 Many physical systems can be represented by a regular arrangement of molecules in a lattice structure. Knowing how neighboring molecules in the lattice interact with one another can give great insight into a material's macroscopic behavior.

Advanced Materials, EarlyView.Uniform monolayer Cr2Ge2Te6 films are achieved on Si substrates by molecular beam epitaxy. Intrinsic ferromagnetism with perpendicular magnetic anisotropy is established in the films by anomalous Hall effect and superconducting quantum interference device measurements, albeit with strong magnetic fluctuations characteristic of its 2D nature.

Seamless Mechanical Programming Through Hybrid Epoxy–Acrylate Printing for Soft–Rigid Robots
Advanced Materials, EarlyView.Hybrid epoxy‐acrylate printing enables seamless fabrication of soft–rigid robotic systems with covalently integrated interfaces and functionally graded mechanics. Grayscale exposure expands the accessible material space, enabling spatially programmed actuation through patterned stiffness while revealing the mechanics and durability of continuously ...

Tensor Networks for Noninvertible Symmetries in 3+1D and Beyond
Physical Review XTensor networks provide a natural language for noninvertible symmetries in general Hamiltonian lattice models. We use ZX-diagrams, which are tensor network presentations of quantum circuits, to define a noninvertible operator implementing the Wegner ...

Two-Dimensional Ising Model with Competing Interactions as a Model for Interacting pi-Rings [PDF]
, 2009 We investigate the Ising model on a square lattice with antiferromagnetic exchange between nearest and next-nearest neighbors and show that at low temperatures stripe-like and droplet-like superstructures appear.

Phase Diagram of the Ising Model on Percolation Clusters [PDF]
, 1994 The annealed Ising magnet on percolation clusters is studied by means of a mapping into a Potts-Ising model and with the Migdal-Kadanoff renormalization-group method.

Robust Spin Splitting and Fermiology in the Layered Altermagnet CoNb4${\rm CoNb}_4$Se8${\rm Se}_8$
Advanced Materials, EarlyView.The emergence of an altermagnetic phase is demonstrated in the cobalt‐intercalated superconducting 2H‐NbSe2 polymorph. A combined theoretical and experimental approach directly probes the magnetism, the altermagnetic lifting of Kramers degeneracy, and the electronic phase space, establishing CoNb4Se8 as the first g‐wave altermagnetic layered material ...
