Supersolid Phase in the Diluted Holstein Model
Jingyao Meng, Yuxi Zhang, Rafael M. Fernandes +2
The Holstein model on a square lattice at half-filling has a well-established finite temperature phase transition to an insulating state with long range charge density wave (CDW) o…

Site-selective correlations in interacting "flat-band" quasicrystals
Yuxi Zhang, Richard T. Scalettar, Rafael M. Fernandes
Model lattices such as the kagome and Lieb lattices have been widely investigated to elucidate the properties of interacting flat-band systems. While a quasicrystal does not have p…
