Stimulated by a recent experiment observing successfully two superconducting states with even- and odd-number of electrons in a nanowire topological superconductor as expected from the existence of two end Majorana quasiparticles (MQs) [Albrecht et al.,
Landau-Zener transition (LZT) has been explored in a variety of physical systems for coherent population transfer between different quantum states. In recent years, there have been various proposals for applying LZT to quantum information processing because when compared to the methods using ac pulse...
Particulary we investigate a variant of the Landau-Zener problem in which the coupling between the adiabatic levels is induced by an ac field, i.e., the energy level or tunnel coupling oscillates. We consider two limits, namely fast and slow driving in which the transition probability found ...
1.From Landau theory,free energy near the phase transition temperature should be expanded in a power series of the function .由Landau理论 ,相变温度附近的自由能F就可以写成 R幂级数展开的形式。 2.The impact of magnetic field, electric field on the liquid crystal molecules has been studied in thi...
