Linear response theory is a well-established method for exploring excitations of many-body systems. The Quasiparticle Random-Phase Approximation (QRPA), in particular, provides a powerful microscopic framework but is limited by high computational costs. This work presents two complementary QRPA surrogate models that achieve 0.1%–1% accuracy while offering a six to seven order-of-magnitude speedup over state-of-the-art solvers. These emulators enable large-scale studies and Bayesian calibration of computationally expensive physics models. The associated GitHub for these models consists of emulators reflecting the methodologies described in here.

Such analyses include discovery of new particles and processes, measuring cross-sections, and setting limits on new physics. The package itself helps the user build statistical models of expected observations, run tests on the model and observed data, and then provides tools for validating/inspecting/understanding the model and the tests.
