Negative Dwell Times as Resolvent Derivatives: A Structural Operator-Theoretic Explanation of 𝑻𝑻=𝒕𝒈

A structural operator-theoretic account of negative group delays and post-selected excitation times in resonant atomic media. Within a scalar Lorentzian propagation model, the excitation time and the optical delay are shown to be parameter derivatives of the same frequency-resolv...
