Abstract |
|
In their seminal work (in 1932), Lev Landau and Clarence Zener derived a non-perturbative prediction for the transition
probability between the two energy states. This paper is dedicated to the coupled Schr¨odinger system :
¯h
i
dy(t)
dt
=
t2 −z2 2zt
2zt −t2 +z2
y(t) ,
and we aim to compute a local expansion of the transition coefficient a(z) in the adiabatic limit z→0. |
