A new maximum-entropy method with Bayesian optimization extracts self-energies and Eliashberg functions from ARPES data on curved dispersions and is demonstrated on SrTiO3 and graphene.
Uniaxial strain converts altermagnets to ferrimagnets with correlated valley polarization; monolayer VCrSeTeO shows intrinsic valley polarization exceeding 400 meV under strain plus SOC, accompanied by reversed valley Hall voltage within the same valley.
DFT+DMFT calculations find orbital-dependent mass renormalizations, a doping-driven Lifshitz transition with self-doping, and enhanced spin fluctuations suggesting stripe order in La3Ni2O7.
DFT+DMFT shows orbital-selective Mott insulation in single-layer Ni eg states and strongly renormalized quasiparticles (m*/m ~3.5-4.2) in bilayer Ni of La5Ni3O11, plus competing spin-charge density wave stripes at Q=(1/3,1/3) and (1/4,1/4).
