Electron-Phonon Interactions in Flat Band Systems
Chunhan Feng, Richard T. Scalettar
Existing Quantum Monte Carlo studies have investigated the properties of fermions on a Lieb (CuO) lattice interacting with an on-site, or near-neighbor electron-electron coupli…

Charge Density Waves on a Half-Filled Decorated Honeycomb Lattice
Chunhan Feng, Huaiming Guo, Richard T. Scalettar
Tight binding models like the Hubbard Hamiltonian are most often explored in the context of uniform intersite hopping . The electron-electron interactions, if sufficiently large…

Robustness of entropy plateaus: A case study of triangular Ising antiferromagnets
Owen Bradley, Chunhan Feng, Richard T. Scalettar +1
Residual entropy is a key feature associated with emergence in many-body systems. From a variety of frustrated magnets to the onset of spin-charge separation in Hubbard models and…
