QCD axions and domain walls in hot and dense matter of compact stars Open
In compact stellar environments, the stability of dense QCD matter requires the simultaneous fulfillment of charge neutrality and beta equilibrium. In this work, we study how temperature and finite chemical potential affect QCD topology an…

Tuning SWCNT Length to Optimize the Rate–Efficiency–Stability Triad in Nanofluidic Water Channels Open
This work shows that the length of single-walled carbon nanotubes is critical in governing the trade-off among the rate, efficiency, and stability of pressure-driven water transport. A critical length of 1.06 nm marks the transition in the…

New contribution to the anomalous $π^0\rightarrowγγ$ decay in SU(2) chiral perturbation theory Open
The introduction of axions gives rise to additional one-loop diagrams for the two-photon decays of neutral pions via axion-pion mixing. We compute this correction that has been overlooked in existing calculations, within the framework of S…

MobiEdit: Resource-efficient Knowledge Editing for Personalized On-device LLMs Open
Large language models (LLMs) are deployed on mobile devices to power killer applications such as intelligent assistants. LLMs pre-trained on general corpora often hallucinate when handling personalized or unseen queries, leading to incorre…

New axion contribution to the two-photon decays of neutral pions Open
The presence of axions introduces new diagrams at one-loop order to the two-photon decays of the neutral pion through axion-pion mixing. In this work, we calculate this correction, missing in all current calculations, in the framework of S…
