Entangling power in Heisenberg spin chains shows a monotonic decrease with growing symmetry in small models, sharp dips at SU(2) and free-fermion points in finite chains, and vanishes at SU(2) points but maximizes at the free-fermion point in the thermodynamic limit for the S-matrix.
An optical superlattice architecture is proposed to implement the three-band Emery model with ultracold fermions, allowing simulation of cuprate-like band structure, interactions, and thermodynamics.
Ultralight Bose gases in MOND show an angle-dependent dispersion relation that produces orientation-varying Jeans instability.
Classical simulation of quantum annealing for the 1D Hubbard model up to 40 qubits reports substantial speed-up over Bethe-ansatz methods for half-filled cases.
