  • S matrix from matrix product states 
    Vanderstraeten, Laurens; Haegeman, Jutho; Osborne, Tobias J.; Verstraete, Frank (College Park, MD : American Physical Society, 2014)
    We use the matrix product state formalism to construct stationary scattering states of elementary excitations in generic one-dimensional quantum lattice systems. Our method is applied to the spin-1 Heisenberg antiferromagnet, ...
  • Time-dependent variational principle for quantum lattices 
    Haegeman, Jutho; Cirac, J. Ignacio; Osborne, Tobias J.; Pižorn, Iztok; Verschelde, Henri; Verstraete, Frank (College Park, MD : American Physical Society, 2011)
    We develop a new algorithm based on the time-dependent variational principle applied to matrix product states to efficiently simulate the real- and imaginary-time dynamics for infinite one-dimensional quantum lattices. ...
  • Variational matrix product ansatz for nonuniform dynamics in the thermodynamic limit 
    Milsted, Ashley; Haegeman, Jutho; Osborne, Tobias J.; Verstraete, Frank (College Park, MD : American Physical Society, 2013)
    We describe how to implement the time-dependent variational principle for matrix product states in the thermodynamic limit for nonuniform lattice systems. This is achieved by confining the nonuniformity to a (dynamically ...
