Commensurate-incommensurate transition in two-coupled chains of nearly half-filled electrons
TL;DR: In this article, the physical properties of two coupled chains of electrons, with a nearly half-filled band, as a function of the interchain hopping t ≥ 0 and the doping were investigated.
Journal ArticleDOI
Mott-superfluid transition in bosonic ladders
P. Donohue,Thierry Giamarchi +1 more
TL;DR: In this article, it was shown that in a commensurate bosonic ladder, a quantum phase transition occurs between a Mott insulator and a superfluid when interchain hopping increases.
Journal ArticleDOI
Spinless fermion ladders at half filling
TL;DR: In this paper, a half-filled ladder of spinless fermions was studied and it was shown that contrary to a single chain, the ladder becomes a Mott insulator for arbitrarily small repulsive interactions.
