Applications of the density matrix renormalisation group to problems in magnetism
G. A. Gehring, R. J. Bursill, T. Xiang
We review White's density matrix renormalisation group method, an increasingly popular method for the solution of low dimensional quantum Hamiltonians. We describe some application…

Numerical and approximate analytical results for the frustrated spin-1/2 quantum spin chain
R. J. Bursill, G. A. Gehring, D. J. J. Farnell +3
We study the frustrated phase of the quantum spin- system with nearest-neighbour and next-nearest-neighbour isotropic exchange known as the Majumdar-Ghosh Hami…

Density matrix renormalisation group study of the correlation function of the bilinear-biquadratic spin-1 chain
R. J. Bursill, T. Xiang, G. A. Gehring
Using the recently developed density matrix renormalization group approach, we study the correlation function of the spin-1 chain with quadratic and biquadratic interactions. This…
