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…
Strings on type IIB pp-wave backgrounds with interacting massive theories on the worldsheet
Alin Tirziu, Paul Fendley
We consider superstring theories on pp-wave backgrounds which result in an integrable supersymmetric Landau-Ginzburg theory on the worldsheet. We obtain exact eige…
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…
Lattice fermion models with supersymmetry
Paul Fendley, Bernard Nienhuis, Kareljan Schoutens
We investigate a family of lattice models with manifest N=2 supersymmetry. The models describe fermions on a 1D lattice, subject to the constraint that no more than k consecutive l…
