Two-loop matching of renormalizable operators: general considerations and applications
Journal of High Energy Physics, 2021 Low-energy effective field theories (EFT) encode information about the physics at high energies — i.e., the high-energy theory (HET). To extract this information the EFT and the HET have to be matched to each other. At the one-loop level, general results

Dynamics of Nambu monopole in two Higgs doublet models. Cosmological Monopole Collider
Journal of High Energy Physics, 2020 We study the dynamics of the Nambu monopole in two Higgs doublet models, which is a magnetic monopole attached by two topological Z strings (Z flux tubes) from two opposite sides. The monopole is a topologically stable solution of the equation of motions

Tip-Fin Mild Flutter Analysis Using the Doublet-Point Method for Non-Planar Lifting Surfaces.
Journal of the Japan Society for Aeronautical and Space Sciences, 1995 Flutter calculations were carried out on the results of fundamental wind-tunnel experiments on tip-fin configuration wings. In the experiments, mild flutter has been observed within a certain range of flow speed which was well below the violent flutter point.
