(a) The energy spectrum of the total Hamiltonian as a function of the depth. The vertical blue line denotes V0 = 2.53c2. (b) V0(t) as a function of time. Left and right empty triangles (at t1 and t4) mark the times when the bound state dives and leaves the Dirac sea. Left and right filled triangles (at t2 and t3) separate the three time regions.
