We discuss the rich phase diagram of doped AB 2 tJ chains by using data from density
matrix renormalization group and exact diagonalization techniques. The J vs δ (hole do**) …

Frustrated one-dimensional quantum spin systems are known to exhibit a variety of quantum
ground states due to the effects of quantum fluctuations and frustrations. In a spin-1 2 …
