Quantum droplets of quasi-one-dimensional dipolar Bose-Einstein condensates [PDF]
J. Phys. Commun. 4 125008 (2020), 2020 Ultracold dipolar droplets have been realized in a series of ground-breaking experiments, where the stability of the droplet state is attributed to beyond-mean-field effects in the form of the celebrated Lee-Huang-Yang (LHY) correction. We scrutinize the dipolar droplet states in a one-dimensional context using a combination of analytical and numerical

Perturbation Theory for Propagating Magnetic Droplet Solitons [PDF]
Proceedings of the Royal Society A, 471, 20150042, 2015, 2015 Droplet solitons are a strongly nonlinear, inherently dynamic structure in the magnetization of ferromagnets, balancing dispersion (exchange energy) with focusing nonlinearity (strong perpendicular anisotropy). Large droplet solitons have the approximate form of a circular domain wall sustained by precession and, in contrast to single magnetic vortices,

SARS-CoV-2 virus transfers to skin through contact with contaminated solids
Scientific Reports, 2021 Transfer of SARS-CoV-2 from solids to fingers is one step in infection via contaminated solids, and the possibility of infection from this route has driven calls for increased frequency of handwashing during the COVID-19 pandemic.

Extinction of incident hydrogen/air detonation in fine water sprays [PDF]
, 2021 Two-dimensional numerical simulations with Eulerian-Lagrangian method are conducted to study propagation and extinction of stoichiometric hydrogen/air detonations in fine water sprays. Parameterized by water mass loading and initial droplet size, a detonation extinction map is developed. Detonation extinction would occur with larger mass loading and/or
