Layer‐Dependent Phonon Polaritons in hBN Resolved by Photo‐Induced Force Spectroscopy

open access: yesAdvanced Science, EarlyView.
Layer‐dependent phonon polariton resonances in hexagonal boron nitride are systematically investigated using photo‐induced force microscopy. The in‐plane resonance exhibits a blueshift, while the out‐of‐plane resonance shows a redshift with increasing thickness. These results establish layer number as a key parameter for tuning polaritonic responses in

Jemaa El-Fna ou l’exotisme durable

open access: yesGéographie et Cultures, 2009
Exoticism has been proclaimed dead for more than a century. This paper argues that it did not disappear. Jemaa El-Fna Square (Marrakech) illustrates the sustainability of exoticism. The image of this square did not change much in Western literature since

Magnetotransport Signatures of Spin–Orbit Coupling in High‐Temperature Cuprate Superconductors

open access: yesAdvanced Science, EarlyView.
Large angle‐dependent magnetoresistance and planar Hall effects emerge at the superconducting transition of YBa2Cu3O7−x$\mathrm{YBa_2Cu_3O_{7-x}}$ thin films. These anomalous transport signatures, absent in the normal state, point to spin‐polarized quasiparticle dynamics enabled by an unexpected spin–orbit coupling landscape in cuprate superconductors,

Emergent 3D Fermiology and Magnetism in an Intercalated Van der Waals System

open access: yesAdvanced Science, EarlyView.
An emergent three‐dimensional electronic state is uncovered in an intercalated van der Waals system. A spin‐polarized intercalant‐host hybridized band crossing the Fermi level provides an itinerant channel for interlayer exchange, highlighting how electronic dispersion governs magnetic dimensionality.

Red Blood Cells as Endogenous Biotweezers for Optical Micromanipulation In Vivo

open access: yesAdvanced Science, EarlyView.
By synergistically integrating the long‐distance manipulation fiber probe (LDMFP) and endogenous red blood cells (RBCs) as biocompatible optical elements, a natural RBC biotweezer was developed for the desired microparticle manipulation and immune cell activation within living vasculature, which might offer an alternative tool for intravital optical ...

Tropical Landscapes and Nature-Culture Entanglements: Reading Tropicality via Avatar

open access: yeseTropic: electronic journal of studies in the tropics, 2022
Landscape integrates both natural and cultural aspects of a particular geographical area. Environmental elements include geological landforms, waterscapes, seascapes, climate and weather, flora and fauna.

CLRe: A Synergistic Dual‐Engine Framework for One‐Step Retrosynthesis Prediction

open access: yesAdvanced Science, EarlyView.
CLRe uses a contrastive difficulty score to order pretrained seq2seq fine‐tuning for retrosynthesis. Reaction embeddings define the ranking score, and a cumulative easy‐to‐hard schedule expands from the easiest subset to the full training set while earlier examples remain active.

Flat Bands Induced by Non‐Collinear Antiferromagnetism in CoBi2Te4

open access: yesAdvanced Science, EarlyView.
Flat bands emerge at the edges of intrinsically non‐collinear antiferromagnetic CoBi2Te4 two‐septuple layers through the interplay of spin–orbit coupling–driven band inversion and non‐collinear antiferromagnetism, uncovering a previously unexplored mechanism for flat‐band formation and opening new opportunities for strongly correlated quantum states ...

A born-translated fairy tale: transcultural readership and anti-exoticism in Robert Louis Stevenson’s “The Bottle Imp”

open access: yesAltre Modernità, 2018
The six years Robert Louis Stevenson spent in the Pacific region offer a particularly stark contrast with his received image as an uncommitted romancer (and hence, in the context of British colonialism, as a tacit supporter of imperialism).
