a Schematic of a minimal rectangular tight-binding model of competing singlet and triplet pairing instabilities. b Free energy landscape plot of \(\,{{\mbox{Re}}}\,({\Delta }_{{p}_{x}})\) vs Re(Δs), with the time-dependent trajectory in (c) plotted in green. c Time plots of Ax(t) and ∣Δi(t)∣ for stotal [Methods], px, and py order parameters subjected to an example Gaussian pulse. d Schematic plot showing the spectral profile of the pulse in (c) in relation to the Bardasis-Schrieffer mode frequency ΩBS and the edge of the quasiparticle continuum (QPC). e A parametric plot of fluence versus inverse pulse width showing the final state induced by a family of Gaussian pulses, with frequency Ω = 0.75 ΩBS centered slightly below the BS mode frequency. A star indicates the pulse parameters used in b–d.
