Capillary orbits [PDF]

open access: yesNature Communications, 2019
AbstractMillimeter-sized objects trapped at a liquid surface distort the interface by their weight, which in turn attracts them towards each other. This ubiquitous phenomenon, colloquially called the “Cheerios effect” is seen in the clumping of cereals in a breakfast bowl, and turns out to be a highly promising route towards controlled self-assembly of

Tuning Ising superconductivity with layer and spin–orbit coupling in two-dimensional transition-metal dichalcogenides [PDF]

open access: yesNature Communications, 2017
Systems simultaneously exhibiting superconductivity and spin–orbit coupling are predicted to provide a route toward topological superconductivity and unconventional electron pairing, driving significant contemporary interest in these materials. Monolayer

Thermal Bending of the Rotor Due to Rotor-to-Stator Rub

open access: yesInternational Journal of Rotating Machinery, 2000
The rotor thermal bending due to the rotor-to-stator rubbing can lead to one of three types of observed rotor lateral motion: (1) spiral with increasing amplitude, (2) oscillating between rub]no-rub conditions, and (3) asymptotical approach to the rotor ...

Room temperature magnetization switching in topological insulator-ferromagnet heterostructures by spin-orbit torques [PDF]

open access: yesNature Communications, 2017
Topological insulators with spin-momentum-locked topological surface states are expected to exhibit a giant spin-orbit torque in the topological insulator/ferromagnet systems.

Spin–orbit-coupled Bose–Einstein condensates [PDF]

open access: yesNature, 2011
Spin–orbit (SO) coupling—the interaction between a quantum particle’s spin and its momentum—is ubiquitous in physical systems. In condensed matter systems, SO coupling is crucial for the spin-Hall effect and topological insulators; it contributes to the ...

A Study on the Derivation of Atmospheric Water Vapor Based on Dual Frequency Radio Signals and Intersatellite Communication Networks

open access: yesAerospace, 2023
The atmospheric total water vapor content (TWVC) affects climate change, weather patterns, and radio signal propagation. Recent techniques such as global navigation satellite systems (GNSS) are used to measure TWVC but with either compromised accuracy ...

Congenital upper eyelids ectropion in Down’s syndrome

open access: yesGMS Ophthalmology Cases, 2017
Congenital bilateral ectropion of the upper eyelids is a rare, benign condition reported in ophthalmic literature. It is more frequently associated with Down’s syndrome, ichthyosis, and sporadic cases in newborns from black population.

Meson-like Baryons and the Spin-Orbit Puzzle [PDF]

open access: yes, 1999
I describe a special class of meson-like \Lambda_Q excited states and present evidence supporting the similarity of their spin-independent spectra to those of mesons.
