Quantum Criticality and Incipient Phase Separation in the Thermodynamic Properties of the Hubbard Model
D. Galanakis, E. Khatami, K. Mikelsons +4
Transport measurements on the cuprates suggest the presence of a quantum critical point hiding underneath the superconducting dome near optimal hole doping. We provide numerical ev…

Thermodynamics of the Antiferromagnetic Heisenberg Model on the Checkerboard Lattice
Ehsan Khatami, Marcos Rigol
Employing numerical linked-cluster expansions (NLCEs) along with exact diagonalizations of finite clusters with periodic boundary condition, we study the energy, specific heat, ent…
