Accelerating an adiabatic process by nonlinear sweeping
Xingxin Cao, Jun Zhuang, X. -J. Ning +1
We investigate the acceleration of an adiabatic process with the same survival probability of the ground state by sweeping a parameter nonlinearly, fast in the wide gap region and…
Quantum Zeno and anti-Zeno effects induced by either frequent measurements, modulations, or a mix of them
Wenxian Zhang, A. G. Kofman, Jun Zhuang +2
Using numerical calculations, we compare the collective transition probabilities of many spins in random magnetic fields, subject to either frequent projective measurements, freque…
Crtierion of effective centre-of-mass method in Quantum Mechanics
Bo-Yuan Ning, Jun Zhuang, Xi-Jing Ning
In describing the motion of atoms and clusters, we face with choosing quantum mechanics or classical mechanics under different conditions. In principle, there exist two criteria fo…
Dynamical control of two-level system's decay and long time freezing
Wenxian Zhang, Jun Zhuang
We investigate with exact numerical calculation coherent control of a two-level quantum system's decay by subjecting the two-level system to many periodic ideal phase modulati…
