Topological to magnetically ordered quantum phase transition in antiferromagnetic spin ladders with long-range interactions
Luhang Yang, Phillip Weinberg, Adrian E. Feiguin
We study a generalized quantum spin ladder with staggered long range interactions that decay as a power-law with exponent . Using large scale quantum Monte Carlo (QMC) and the d…

The fate of pairing and spin-charge separation in the presence of long-range antiferromagnetism
Luhang Yang, Ignacio Hamad, Luis O. Manuel +1
We present a numerical study of competing orders in the 1D - model with long-range RKKY-like staggered spin interactions. By circumventing the constraints imposed by Mermin-W…
