Topological Order and Conformal Quantum Critical Points
Eddy Ardonne, Paul Fendley, Eduardo Fradkin
We discuss a certain class of two-dimensional quantum systems which exhibit conventional order and topological order, as well as two-dimensional quantum critical points separating…

Competing density-wave orders in a one-dimensional hard-boson model
Paul Fendley, K. Sengupta, Subir Sachdev
We describe the zero-temperature phase diagram of a model of bosons, occupying sites of a linear chain, which obey a hard-exclusion constraint: any two nearest-neighbor sites may h…
