Discrete worldline instantons
Christian Schneider, Greger Torgrimsson, Ralf Schützhold
The semiclassical approximation of the worldline path integral is a powerful tool to study nonperturbative electron-positron pair creation in spacetime-dependent background fields.…
Dynamically assisted Sauter-Schwinger effect - non-perturbative versus perturbative aspects
Greger Torgrimsson, Christian Schneider, Johannes Oertel +1
The Sauter-Schwinger effect predicts the creation of electron-positron pairs out of the quantum vacuum by a strong and slowly varying electric field. This effect can be dynamically…
Prefactor in the dynamically assisted Sauter-Schwinger effect
Christian Schneider, Ralf Schützhold
The probability of creating an electron-positron pair out of the quantum vacuum by a strong electric field can be enhanced tremendously via an additional weaker time-dependent fiel…
Pulse shape dependence in the dynamically assisted Sauter-Schwinger effect
Malte F. Linder, Christian Schneider, Joachim Sicking +2
While the Sauter-Schwinger effect describes nonperturbative electron-positron pair creation from vacuum by a strong and slowly varying electric field via tunn…
Dynamically assisted Sauter-Schwinger effect in inhomogeneous electric fields
Christian Schneider, Ralf Schützhold
Via the worldline instanton method, we study electron-positron pair creation by a strong electric field of the profile superimposed by a weaker pulse $E'/\cosh^2(ωt…
