Hamiltonian structure of passive defect dynamics in two-dimensional nematic liquid crystals in unbounded domains

Abstract Hamiltonian structures for the passive dynamics of topological defects in nematic liquid crystals in two-dimensional systems are presented. Following the work by Miyoshi et al. (Miyoshi et al. 2024 Proc. R. Soc. A 480, 20240405. (doi:10.1098/rspa.2024.0405)), which demon...

Impulse-induced liquid jets from bubbles with arbitrary contact angles

This paper investigates the relationship between the contact angle of a spherical bubble attached to a tube submerged in a container and the jet speed induced by an impulsive acceleration at its base. While it has been well established that bubble geometry strongly influences the...
