Structural phase transitions in multipole traps
Structural phase transitions multipole traps
2012/2/28
A small number of laser-cooled ions trapped in a linear radiofrequency multipole trap forms a hollow tube structure. We have studied, by means of molecular dynamics simulations, the structural transit...

By means of molecular-dynamics simulations, temperature driven diffusionless structural phase
transitions in equi- and nearly equiatomic ordered nickel-titanium alloys were investigated. For this pur...
