Quantum tunnelling from vacuum in multidimensions
Ibrahim Akal, Gudrid Moortgat-Pick
The tunnelling of virtual matter-antimatter pairs from the quantum vacuum in multidimensions is studied. We consider electric backgrounds as a linear combination of a spatial Saute…

Euclidean mirrors: enhanced vacuum decay from reflected instantons
Ibrahim Akal, Gudrid Moortgat-Pick
We study the tunneling of virtual matter-antimatter pairs from the quantum vacuum in the presence of a spatially uniform, time-dependent electric background composed of a strong, s…
