Quantized heat flow in the Hofstadter butterfly

This study demonstrates that heat transport in the Hofstadter butterfly, realized in a graphene/hexagonal boron nitride moiré superlattice, is universally quantized according to topological invariants across quantum Hall states, Chern insulators, and interaction-driven symmetry-broken phases, thereby confirming the deep link between thermal conductance and topological order.

Ferroelectric polarization mapping through pseudosymmetry-sensitive EBSD reindexing

This paper introduces an advanced electron backscatter diffraction (EBSD) reindexing technique that utilizes simulated pattern-matching and a novel pseudosymmetry-sensitive confidence index to successfully map local ferroelectric polarization directions in complex polycrystalline materials, overcoming previous limitations in distinguishing closely related domain variants.

Interferometric Readout of Momentum-Space Topology in a Programmable Dissipative Photonic Circuit

This paper demonstrates a programmable photonic circuit that utilizes unitary dilation and interferometric readout to successfully resolve momentum-space topology, including Zak phases and Chern numbers, within strongly dissipative non-Hermitian dynamics where traditional amplitude-based detection fails.

Emergent Quantum Geometric Phases in Holey Graphene

This paper demonstrates that lithographically patterned periodic antidot lattices in high-quality monolayer graphene enable the controlled observation of emergent quantum geometric phases and moiré-like electronic spectra through tunable commensurability effects, establishing a scalable platform for exploring moiré physics without the need for multilayer stacking or lattice mismatch.

Anisotropic wavevector-dependent damping of thickness-quantized magnons

Using high-resolution parametric-instability spectroscopy on yttrium iron garnet films, this study reveals that thickness-quantized magnon damping is anisotropic and wavevector-dependent, increasing with mode number and varying based on propagation geometry, thereby challenging the common assumption of a mode-independent damping parameter.

Topological Fermi-polaron Polaritons with Electrically Invertible Topology

This paper demonstrates the creation of Fermi-polaron polaritons in a gate-controlled transition-metal dichalcogenide photonic crystal, where the interplay of many-body interactions and light-matter coupling enables electrically invertible topological gaps and Chern numbers, overcoming the limitations of weak Zeeman splittings in semiconductor polariton systems.

Multi-Branch Transport in a Back-gated WS2_2 Transistor at Deep-Cryogenic Temperature

This paper demonstrates that a back-gated multilayer WS2_2 transistor maintains strong gate tunability with an on/off ratio exceeding 10510^5 down to 20 mK, exhibiting reproducible shoulder-like turn-on features that are explained by a phenomenological model of multiple parallel conduction branches.
