Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters

open access: yesAdvanced Functional Materials, EarlyView.
An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Dirac Semimetallicity Enabled by Stripe Antiferromagnetism in Monolayer FeSe

open access: yesAdvanced Functional Materials, EarlyView.
In monolayer FeSe, stripe antiferromagnetic order selectively breaks mirror symmetry, enabling odd inter‐orbital hybridization between opposite‐parity Fe 3d states. This mechanism stabilizes symmetry‐protected Dirac nodes with nontrivial Wilson‐loop topology and edge states, accompanied by a strong orbital diamagnetic susceptibility as an experimental ...

Convergence of Invariant Measures of Truncation Approximations to Markov Processes

open access: yesApplied Mathematics, 2012
Let Q be the Q-matrix of an irreducible, positive recurrent Markov process on a countable state space. We show that, under a number of conditions, the stationary distributions of the n × n north-west corner augmentations of Q converge in total variation to the stationary distribution of the process.

Switching Superconductivity with Uniaxial Strain in a high‐Tc${\rm T}_{c}$ Cuprate Superconductor

open access: yesAdvanced Functional Materials, EarlyView.
Uniaxial strain is demonstrated as a new scheme for a superconductivity switch. Exploiting the large strain‐induced Tc shift in a cuprate superconductor enables robust switching between superconducting and normal states over 100 cycles with only 0.1% strain.

Deformation‐Tolerant Functional Elastomer Overlayers for Haze‐Assisted Light Extraction and Color Conversion in Stretchable Mechanoluminescent Films

open access: yesAdvanced Functional Materials, EarlyView.
Functional elastomer overlayers are integrated onto stretchable ZnS:Cu‐PDMS mechanoluminescent films to regulate light after emission without modifying the emissive composite. NLC‐PU provides haze‐assisted light extraction to enhance green mechanoluminescence, while DCM‐NLC‐PU combines green‐to‐yellow‐orange color conversion with enhanced outward light

Orbital Engineering through Strain‐Induced Spin–Orbit–Lattice Coupling in Sr2FeReO6 Double Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
Epitaxial strain drives oxygen‐octahedral reconfiguration in Sr2FeReO6 double‐perovskite thin films, inducing orbital‐selective reconstruction of Re 5d states through modified Fe–O–Re hybridization. This coupled lattice–orbital response enables magnetic easy‐axis reversal and a transition from metallic‐like to semiconducting‐like transport.

Thickness‐Programmable Opto‐Memristive Dynamics in 6‐In Wafer‐Scale Atomic‐Layer‐Controlled WS2 for Reservoir Computing

open access: yesAdvanced Functional Materials, EarlyView.
A 6‐in wafer‐scale atomic‐layer‐controlled tungsten disulfide (WS2) is achieved by combining plasma‐assisted synthesis with three‐gas reactive ion etching. Precise layer control enables tunable band‐gap evolution and pulse‐history‐dependent opto‐memristive dynamics.

The cross-country measurement comparability in the immigration module of the European Social Survey 2014-15

open access: yesSurvey Research Methods, 2018
The 7th round of the European Social Survey (ESS) from 2014-15 includes a partial repetition of the immigration module from the first ESS wave (2002-03) with information on individual attitudes toward immigration and immigrants in both old and new ...

Approximation of invariant measures for random lattice reversible Selkov systems

open access: yesDiscrete and Continuous Dynamical Systems - B
This paper focuses on the numerical approximation of random lattice reversible Selkov systems. It establishes the existence of numerical invariant measures for random models with nonlinear noise, using the backward Euler-Maruyama (BEM) scheme for time discretization.
