Numerical work on ν=1/2 bosonic flat-band models reports a vestigial gapless CDW between FCI and finite-momentum SS on checkerboard lattice and FCI-Solid I-Solid II transitions on honeycomb lattice, both driven by roton-mode softening.
Large-scale quantum Monte Carlo simulations provide direct microscopic evidence for a fermion-quadrupling condensate with transition temperature on the scale of the hopping energy.
Driving a double quantum dot out of equilibrium produces a high-bias resonance for two-Cooper-pair exchange with a tunable Andreev current peak whose width scales with quartet coupling and equal auto- and cross-correlations as a signature of coherent quartet oscillations.
