Superconductivity and charge density wave order in the 2D Holstein model
Owen Bradley, George G. Batrouni, Richard T. Scalettar
The Holstein Hamiltonian describes fermions hopping on a lattice and interacting locally with dispersionless phonon degrees of freedom. In the low density limit, dressed quasiparti…

Thermodynamic behavior of modified integer-spin Kitaev models on the honeycomb lattice
Owen Bradley, Jaan Oitmaa, Diptiman Sen +1
We study the thermodynamic properties of modified spin- Kitaev models introduced by Baskaran, Sen and Shankar (Phys. Rev. B 78, 115116 (2008)). These models have the property th…

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…
