The Dynamics of 1D Quantum Spin Systems Can Be Approximated Efficiently
Tobias J. Osborne
In this Letter we show that an arbitrarily good approximation to the propagator e^{itH} for a 1D lattice of n quantum spins with hamiltonian H may be obtained with polynomial compu…

Lower Bound for the Ground-State Energy Density of a 1D Quantum Spin System
Tobias J. Osborne
We present a simple method to calculate systematic lower bounds for the ground-state energy density of a 1D quantum spin system.

General Monogamy Inequality for Bipartite Qubit Entanglement
Tobias J. Osborne, Frank Verstraete
We consider multipartite states of qubits and prove that their bipartite quantum entanglement, as quantified by the concurrence, satisfies a monogamy inequality conjectured by Coff…
