Lie transformation on shortcut to adiabaticity in parametric driving quantum system
Jian-jian Cheng, Yao Du, Lin Zhang
Shortcut to adiabaticity (STA) is a speed way to produce the same final state that would result in an adiabatic, infinitely slow process. Two typical techniques to engineer STA are…
As vacancies, Ga antisites and Au impurities in Zincblende and Wurtzite GaAs nanowire segments from first principles
Yaojun A. Du, Sung Sakong, Peter Kratzer
In this paper some specific issues related to point defects in GaAs nanowires are addressed with the help of density functional theory calculations. These issues mainly arise from…
Diffusion of hydrogen within idealised grains of bcc-Fe: A kinetic Monte Carlo study
Yaojun A. Du, Jutta Rogal, Ralf Drautz
Structural defects in materials such as vacancies, grain boundaries, and dislocations may trap hydrogen and a local accumulation of hydrogen at these defects can lead to the degrad…
Fast Diffusion Mechanism of Silicon Tri-interstitial Defects
Yaojun A. Du, Stephen A. Barr, Kaden R. A. Hazzard +3
We reveal the microscopic self-diffusion process of compact tri-interstitials in silicon using a combination of molecular dynamics and nudged elastic band methods. We find that the…
