Order and supersymmetry at high filling zero energy states on the triangular lattice
D. Galanakis, C. L. Henley, S. Papanikolaou
We perform exact diagonalization studies in d=2 dimensions for the Fendley and Schoutens model of hard-core and nearest-neighbor excluding fermions that displays an exact non-relat…
Role of the van Hove Singularity in the Quantum Criticality of the Hubbard Model
K. -S. Chen, S. Pathak, S. -X. Yang +5
A quantum critical point (QCP), separating the non-Fermi liquid region from the Fermi liquid, exists in the phase diagram of the 2D Hubbard model [Vidhyadhiraja et. al, Phys. Rev.…
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…
Comment on ``Exact bosonization for an interacting Fermi gas in arbitrary dimensions''
Dimitrios Galanakis, Shuxiang Yang, Fakher Assaad +3
This a comment on arXiv:0907.3243v2. We demonstrate that the method proposed by Efetov {\it et. al.} is just a reformulation of the Blankenbeckler, Scalapino, and Sugar approach an…
Thermodynamics of the Quantum Critical Point at Finite Doping in the 2D Hubbard Model: A Dynamical Cluster Approximation Study
K. Mikelsons, E. Khatami, D. Galanakis +3
We study the thermodynamics of the two-dimensional Hubbard model within the dynamical cluster approximation. We use continuous time quantum Monte Carlo as a cluster solver to avoid…
Quantum Criticality Due to Incipient Phase Separation in the Two-dimensional Hubbard Model
E. Khatami, K. Mikelsons, D. Galanakis +4
We investigate the two-dimensional Hubbard model with next-nearest-neighbor hopping, t', using the dynamical cluster approximation. We confirm the existence of a first-order phase-…
