DMRG Study of Critical Behavior of the Spin-1/2 Alternating Heisenberg Chain
T. Papenbrock, T. Barnes, D. J. Dean +2
We investigate the critical behavior of the S=1/2 alternating Heisenberg chain using the density matrix renormalization group (DMRG). The ground-state energy per spin and singlet-t…

Ground-state properties of hard core bosons in one-dimensional harmonic traps
T. Papenbrock
The one-particle density matrices for hard core bosons in a one-dimensional harmonic trap are computed numerically for systems with up to 160 bosons. Diagonalization of the density…
