Many-body quantum beats — interaction-modulated amplitude oscillations of two hopping pairs — explain the slow number-entropy growth in quasiperiodic MBL systems and are consistent with MBL stability.
Adding a constant offset to the quasiperiodic potential in the diamond chain transforms anomalous mobility edges into conventional ones and demonstrates Avila's global theory fails to predict mobility edge locations.
In the Zeno regime of a continuously monitored Aubry-André-Harper chain, an effective non-Hermitian Hamiltonian derived from self-consistent measurement potentials yields a Lyapunov exponent whose predicted localization length quantitatively matches numerical quantum-state-diffusion trajectories.
A flow equation for the resonance density exponent θ(w) derived in the SJA predicts resonance proliferation driving delocalization, with θ(w)>0 for localized phases and instability signaling thermalization, matching numerics in Anderson and MBL models.
A momentum clustering method generalizes Hatsugai-Kohmoto models and recovers ground-state energies to within 1% of DMRG using two-site clusters in the Aubry-André-Hubbard model for strong onsite potentials.
