Optical Pulling Force on Gold Mie Particles via Germanium and Aluminum‐Based Structures

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
This work demonstrates a novel approach to generate optical pulling force on gold Mie objects of two different shapes and studies the effects for different object sizes, incident angles, and the aluminum tetrahedra separation. Using rectangular germanium blocks combined with aluminum tetrahedra, optical pulling force (OPF) is achieved over a broad ...

Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities

Laser &Photonics Reviews, Volume 20, Issue 12, 18 June 2026.
The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...

Fano regime of transport through open quantum dots [PDF]

, 2010
We analyze a quantum dot strongly coupled to the conducting leads via quantum point contacts - Fano regime of transport - and report a variety of resonant states which demonstrate the dominance of the interacting resonances in the scattering process in a

Quasi‐BIC and Reflective Mode Coupling Drives SHG Beyond the Q Factor Limit

Small, Volume 22, Issue 32, 8 June 2026.
An analytical expression is developed to relate second‐harmonic generation to both the resonance Q factor and absorptance. Simulations and experiments on a dual‐resonance 3R‐MoS2 metasurface validate the formula, showing that absorptance engineering provides an effective route to enhance SHG beyond conventional Q‐only design.

THE PSEUDO-INDEX OF HOROSPHERICAL FANO VARIETIES [PDF]

International Journal of Mathematics, 2010
We prove a conjecture of Bonavero et al. on the pseudo-index of smooth Fano varieties, in the special case of horospherical varieties.

Clinical recommendations for early identification of patients with open‐angle glaucoma at higher risk of low adherence to topical treatment: An Italian Delphi consensus

Acta Ophthalmologica, Volume 104, Issue 4, Page 384-395, June 2026.
Abstract Purpose It is important for clinicians to identify patients with glaucoma at higher risk of poor adherence to topical therapy at an early stage to prescribe alternative treatments. An expert‐based set of statements was developed to assist clinicians in the early identification of patients at high risk of low adherence and subsequent poorer ...

Automorphism groups of P1$\mathbb {P}^1$‐bundles over geometrically ruled surfaces

Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract We classify the pairs (X,π)$(X,\pi)$, where π:X→S$\pi \colon X\rightarrow S$ is a P1$\mathbb {P}^1$‐bundle over a non‐rational geometrically ruled surface S$S$ and Aut∘(X)$\mathrm{Aut}^\circ (X)$ is relatively maximal, that is, maximal with respect to the inclusion in the group Bir(X/S)$\mathrm{Bir}(X/S)$.

δ-invariants of Du Val del Pezzo surfaces and K-stability of Fano threefolds [PDF]

Due to the celebrated solution of the Yau–Tian–Donaldson conjecture, it is now known that a smooth Fano variety admits a Kähler–Einstein metric if and only if it is K-polystable.
