WebWe illustrate the idea with applications to the Schwinger effect in sequences of time-dependent electric field pulses, and also to particle production in de Sitter spacetime. The main results are: 1. the time evolution of the super-adiabatic particle number is significantly smoother than in other adiabatic bases, with much smaller fluctuations; 2. WebIn [20,21], the Schwinger e ect is studied in the (anti-)de Sitter spaces and black hole backgounds, representing a uni ed picture of the Schwinger e ect and the Hawking …
