2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/224680We study supersymmetric quantum mechanics with the functional RG formulated in terms of an exact and manifestly off-shell supersymmetric flow equation for the effective action. We solve the flow equation nonperturbatively in a systematic super-covariant derivative expansion and concentrate on systems with unbroken supersymmetry. Already at next-to-leading order, the energy of the first excited state for convex potentials is accurately determined within a 1% error for a wide range of couplings including deeply nonperturbative regimes.24 pages, 8 figures, references added, typos correctedHigh Energy Physics - TheoryHigh Energy Physics - PhenomenologyQuantum Physicstext
