Phonon state tomography decomposes electron-phonon wavefunctions via MPS to reconstruct electronic correlations from phonon occupancy data in optically excited metals.
Perturbations to the chiral Z_p toric code induce Hall-on-Toric descendant states featuring fractional Z_p charges and increased topological degeneracy, identified via iDMRG analysis of entanglement and generalized Hall conductance.
A QR-based CTMRG variant accelerates iPEPS contractions by up to two orders of magnitude on GPUs with no accuracy loss for the Heisenberg and J1-J2 models.
