Physics 4Q03 Lecture 05: This lecture reviews the formalisms of time-independent and time-dependent Rayleigh-Schrodinger perturbation theory for quantum mechanics.
Wilson to Lindblad: Late-time Obstacles to Reliable Calculations with Horizons (and how Open EFTs can help). This talk describes how Open Effective Field Theories can be used to deal with the…
Showed how to find transition amplitudes from the Dyson series. Began analyzing 1st order perturbations constant in time except for being switched on at t=t0.
