| 摘 要： | We propose a universal analytical method of studying the dynamics of a multi-anticrossing system subjected to driving by a single large-amplitude triangle pulse,within a time scale smaller than the dephasing time.Our approach can explain the main features of the Landau-Zener-Stuckelberg interference patterns recently observed in a tripartite system Nature Communications 1 51 (2010)].In particular,we focus on the effect of the size of the anticrossing on interference and compare the calculated interference patterns with numerical simulations.In addition,a Fourier transform of the patterns can extract the information about the energy level spectrum.

| Abstract: | We propose a universal analytical method of studying the dynamics of a multi-anticrossing system subjected to driving by a single large-amplitude triangle pulse, within a time scale smaller than the dephasing time. Our approach can explain the main features of the Landau—Zener—Stückelberg interference patterns recently observed in a tripartite system Nature Communications 1 51 (2010)]. In particular, we focus on the effect of the size of the anticrossing on interference and compare the calculated interference patterns with numerical simulations. In addition, a Fourier transform of the patterns can extract the information about the energy level spectrum. |
