Gutzwiller study of MATBG at ν=2.5 finds dome-shaped FL separating BCS-SC from strongly correlated SC-SC, with nematic SC showing nodal gaps at large U and sFL as possible parent state.
A 114-atom Rydberg kagome array is adiabatically driven into a disordered, correlated state whose spin correlations resemble a U(1) Dirac spin liquid ansatz.
VMC study of two-orbital Hubbard-Kanamori model finds s± superconductivity only near Mott state at half-filling with no orbital selectivity, unlike three-orbital models.
A quasi-1D Kitaev chain from truncated honeycomb shows chiral topological phases with protected edge modes in BDI class and broad continua from fractional excitations in dynamical spin correlations.
Introductory lecture notes on tensor networks with emphasis on matrix-product states, their algorithms, higher-dimensional generalizations, and applications to mixed states and open quantum systems, accompanied by Julia code.
