Thermalization from quenching in coupled oscillators
M. Harinarayanan, Karthik Rajeev
We introduce a finite-time protocol that thermalizes a quantum harmonic oscillator, initially in its ground state, without requiring a macroscopic bath. The method uses a second os…
Hawking radiation from the double copy
Anton Ilderton, William Lindved, Karthik Rajeev
Gravity and gauge theory are concretely linked by the double copy. Although well-studied at the level of perturbative scattering in vacuum, far less is known about non-perturbative…
Tunnelling amplitudes and Hawking radiation from worldline QFT
Anton Ilderton, Karthik Rajeev
We compare Hawking radiation in a collapse background with Schwinger pair creation in an electric field. The comparison is driven by the presence of an analogue horizon in the Schw…
Worldline Modeling of Ultra-Intense Lasers for N-photon Scattering Processes
Ivan Ahumada, Patrick Copinger, James P. Edwards +1
The modeling of present and future ultra-intense lasers demands techniques that go beyond the standard diagrammatic approach to non-perturbatively fully capture the effects of stro…
