A numerical canonical transformation approach to quantum many body problems
Steven R. White
We present a new approach for numerical solutions of ab initio quantum chemistry systems. The main idea of the approach, which we call canonical diagonalization, is to diagonalize…

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…
