The design process of a type-II superconducting device capable of reliably pinning a single Abrikosov vortex is presented, creating a particle-in-a-box-like system. The proposed device consists of a cylindrically symmetric Nb film, 30 nm in diameter and 5 nm thick, with a 14 nm diameter artificial pinning center at its center. Time-dependent Ginzburg–Landau simulations indicate robust single-vortex pinning under an applied field of 6 T. The presumed quantized energy levels and associated quantum wavefunctions of the vortex quasiparticle are obtained by numerically solving the two-dimensional time-independent Schrödinger equation for this system.

The novelty of the present work lies in deriving a generalized Ginzburg–Landau action that explicitly depends on the spacetime metric, where the metric is tuned by an external electric field.

It systematically compares the catalytic performance, flow characteristics, and heat transfer efficiency of packed-bed and wall-mounted catalysts. Through a combination of experimental research and numerical simulation, it was found that wall-mounted catalysts significantly outperform traditional packed catalysts in terms of low pressure drop (pressure drop is only one-third of that of packed catalysts at flow rates of 5–10 m/s) and high hydrogen gas processing capacity (allowing for higher flow rates). The study also revealed the influence of the length-to-diameter ratio of the conversion column on catalytic performance: When the length-to-diameter ratio is between 1.5 and 5, the average conversion rate of para hydrogen increases by 4%, and the outlet temperature decreases by 37.6%.
