Tuning of superconducting properties with disorder in NbxSn nanocrystalline thin films

This study demonstrates that stoichiometry-controlled disorder in nanocrystalline NbxSn thin films significantly tunes superconducting properties by inducing thickness-dependent transitions from superconducting to insulating states and altering dimensionality, with Sn-rich compositions exhibiting enhanced sensitivity to disorder and earlier onset of localization compared to stoichiometric films.

Superconducting diode effect in multichannel Majorana wires

This study demonstrates that multichannel Rashba nanowires with both harmonic and rectangular confinement exhibit robust superconducting diode effects with efficiencies up to ~60%, driven by asymmetric Fulde-Ferrell states that enable high-efficiency nonreciprocal transport and allow for direct topological manipulation of Majorana zero modes via externally injected supercurrents.

Analogue black hole merger in a polariton condensate

This paper demonstrates that polariton condensates provide a unique platform for simulating analogue black hole mergers, showing that while pairs of vortices cannot form a common horizon, systems of four or more vortices can undergo a complete merger governed by a simple geometrical law.

Engineering topology in waveguide arrays

This paper establishes a systematic correspondence between the structural symmetries of one-dimensional Floquet photonic waveguide arrays and their Altland-Zirnbauer topological classification, demonstrating that both bipartite and non-bipartite networks can support topologically protected boundary states through conventional and "shifted" particle-hole symmetries, respectively.

Identifying field-tunable surface resonance states on black phosphorus

Using scanning tunneling spectroscopy, the study reveals that field-tunable surface resonance states on black phosphorus dominate electric field screening and suppress bulk band bending, a mechanism confirmed by a tunable conductance dip and validated by a simplified theoretical model.

Configurational control of photon emission from a molecular dimer

This study demonstrates that the photon emission yield of tin-phthalocyanine dimers on a NaCl/Au(111) surface can be controllably amplified or reduced by switching the configurational state of one molecule, a phenomenon driven by the coupling of adjacent optical transition dipoles.

On-surface synthesis and aromaticity of large cyclocarbons

This study reports the on-surface synthesis of large cyclo[N]carbons (up to N=88) via tip-induced chemistry and demonstrates through transport gap measurements that their aromaticity follows a 4n/4n+2 rule, with the effect persisting at N=42 but diminishing as ring size increases.

Anisotropic two-dimensional magnetoexciton with exact center-of-mass separation

This paper presents an exact analytical framework for separating center-of-mass and relative motions in anisotropic two-dimensional magnetoexcitons, revealing new anisotropy-dependent couplings and providing precise, non-perturbative solutions for magnetoexciton properties in materials like monolayer black phosphorus and titanium trisulfide without relying on stationary-center-of-mass approximations.
