Systematic behaviour of the in-plane penetration depth in d-wave cuprates
C. Panagopoulos, J. R. Cooper, T. Xiang
We report the temperature T and oxygen concentration dependences of the penetration depth of grain-aligned YBa_2Cu_3O_{7-δ} with δ= 0.0, 0.3 and 0.43. The values of the in-plane λ_…
Density matrix renormalisation group for a quantum spin chain at non-zero temperature
R. J. Bursill, T. Xiang, G. A. Gehring
We apply a recent adaptation of White's density matrix renormalisation group (DMRG) method to a simple quantum spin model, the dimerised chain, in order to assess the applicab…
c axis superfluid response of Copper-Oxide superconductors
T. Xiang, J. M. Wheatley
A novel interplay between d-wave superconducting order parameter symmetry and the underlying Cu 3d orbital based electronic structure of Copper-Oxides leads to a striking anisotrop…
Quasiparticle energy dispersion in doped two dimensional quantum antiferromagnets
T. Xiang, J. M. Wheatley
The quasiparticle dispersion in the one-hole t-t'-t"-J model is studied. Both the finite-size diagonalization and the self-consistent Born approximation calculations have been perf…
Density-matrix renormalization-group method in momentum space
T. Xiang
A momentum-space approach of the density-matrix renormalization-group (DMRG) method is developed. Ground state energies of the Hubbard model are evaluated using this method and com…
Superfluid anisotropy in YBCO: Evidence for pair tunneling superconductivity
T. Xiang, J. M. Wheatley
Proximity effect and pair tunneling models are applied as alternative scenarios to explain the recently measured -plane and -axis components of the superfluid tensor in Copp…
