2021/8/11
A new study has presented and characterized the formation and properties of a superparamagnetic ring, which fits snugly around a drop of water due to liquid-liquid interaction, and allows the drops to...
Mysterious Majorana quasiparticle is now closer to being controlled for quantum computing（图）
Majorana quasiparticle controlled quantum computing
2019/10/23
The fame of the Majorana particle stems from its strange properties -- it is the only particle that is its own antiparticle -- and from its potential to be harnessed for future quantum computing.In re...
Controlled absorption and all-optical diode action due to collisions of self-induced transparency solitons
Controlled absorption all-optical diode action collisions of self-induced transparency solitons Optics
2012/4/20
We study inelastic collisions of counter-propagating self-induced transparency solitons in a homogeneously broadened two-level medium. The energy of the pulse can be almost totally absorbed in the med...

Controlled Buckling Crumpling of Nanoparticle-Coated Droplets
2010/11/24
We introduce a new experimental approach to study the structural transitions of large numbers
of nanoparticle-coated droplets as their volume is reduced. We use an emulsion system
where the disperse...
