Zero-damped modes of near-extremal Reissner--Nordström black holes from exact WKB
Prisco Lo Chiatto, Sebastian Schenk, Nils Wagner +1
The late-time ringdown dynamics of near-extremal black holes (BHs) are expected to be dominated by zero-damped modes (ZDMs), whose decay rates are parametrically suppressed relativ…
Exploring Nonperturbative Behaviour of Moments and Cumulants in Quantum Theories
Sebastian Schenk
The dynamics of quantum fields become nonperturbative when their interactions are probed by a large number of particles. To explore this regime we study correlation functions which…
Quantum Imprint of the Anharmonic Oscillator
Prisco Lo Chiatto, Sebastian Schenk, Felix Yu
We study the anharmonic double well in quantum mechanics using exact Wentzel-Kramers-Brillouin (WKB) methods in a 't Hooft-like double scaling limit where classical behavior is exp…
Multiparticle Amplitudes in a Scalar EFT
Valentin V. Khoze, Sebastian Schenk
At sufficiently high energies the production of a very large number of particles is kinematically allowed. However, it is well-known that already in the simplest case of a weakly-c…
Exploring instantons with spin-lattice systems
Sebastian Schenk, Michael Spannowsky
Instanton processes are present in a variety of quantum field theories relevant to high energy as well as condensed matter physics. While they have led to important theoretical ins…
