Lieb-Robinson Bounds for Bose-Hubbard Hamiltonians: A Simplified Proof

A streamlined proof of polynomial Lieb-Robinson light cones (v~t^(d+ε)) for Bose-Hubbard Hamiltonians is derived via ASTLO methods, showing bounded-density initial states constrain quantum information propagation speed in bosonic lattice systems.

Tensor Network Method Offers New Path for Quantum Many‑Body Simulations

A new tensor‑network method redesigns tensor contraction and adds adaptive schemes; early tests show it can handle larger lattice sizes with similar resources. getnews.me/tensor-network-method-of... #tensornetwork #quantummanybody
