The transition between hole-pairs and four-hole clusters in four-leg tJ ladders
Thomas Siller, Matthias Troyer, T. M. Rice +1
Holes weakly doped into a four-leg \tj ladder bind in pairs. At dopings exceeding a critical doping of four hole clusters are observed to form in DMRG calculation…

A Bosonic Model of Hole Pairs
Th. Siller, M. Troyer, T. M. Rice +1
We numerically investigate a bosonic representation for hole pairs on a two-leg t-J ladder where hard core bosons on a chain represent the hole pairs on the ladder. The interaction…
