Packet 3: Tossup 22
An approximation named for these phenomena cannot describe the Schwinger effect since it breaks down when the coupling constant becomes large near Landau poles. Using an approach named for these phenomena on a two-level system can be used to derive the non-crossing theorem and the Rabi problem. The basis of wavefunctions must be mutually orthogonal in order to avoid dividing by zero when calculating the impact of these phenomena on (*) degenerate systems. Wavefunctions are expressed as truncated divergent series in a time-dependent theory of these phenomena that approximates their transition probabilities using Fermi’s Golden Rule. Spin-orbit coupling is an example of these phenomena that are represented as “epsilon” in the Hamiltonian. For 10 points, name these small deviations from a solved system. ■END■
