چکیده
We present the ground state phase diagram of the two-leg Kondo ladder obtained through the density-matrix renormalization group. At half-filling, the spin and charge gaps are non-zero. At other conduction electron densities, we have found fully and partially saturated ferromagnetism, paramagnetism, and dimerized phases at special commensurate fillings. r 2005 Elsevier B.V.

Phase diagram of the two-leg Kondo ladder
The phase diagram of the two-leg Kondo ladder is investigated using computational techniques. Ferromagnetism is present, but only at small conduction electron densities and robust Kondo coupling J. For densities n*0.4 and any Kondo coupling, a paramagnetic phase is found. We also observed spin dimerization at densities n=1/4 and n=1/2. The spin-structure factor at small J peaks at qW = s2n ,0dp...

Using density matrix renormalization group techniques, we have studied the ground state of the 4-leg t-J ladder doped near half-filling. Depending upon J/t and the hole doping x, three types of ground state phases are found: (1) a phase containing d x 2 −y 2 pairs; (2) a striped CDW domain-wall phase, and (3) a phase separated regime. A CDW domain-wall consists of fluctuating hole pairs and thi...
متن کاملHole doping and disorder effects on the one-dimensional Kondo lattice, for ferromagnetic Kondo couplings
We investigate the one-dimensional Kondo lattice model (1D KLM) for ferromagnetic Kondo couplings. The so-called ferromagnetic 2-leg spin ladder and the S=1 antiferromagnet occur as new one-dimensional Kondo insulators. Both exhibit a spin gap. But, in contrast to the strong coupling limit, the Haldane state which characterizes the 2-leg spin ladder Kondo insulator cannot fight against very wea...

Studies of the t-J two-leg ladder via series expansions Abstract Series expansions at T = 0 are used to study properties of the half-filled t-J ladder doped with one or two holes, and at quarter filling. Dispersion curves are obtained for one-hole symmetric and antisymmetric (bonding and antibonding) excitations and for the two-hole bound state. The line in the phase diagram which separates bou...
