Global space-time update
V. G. Rousseau, D. Galanakis
The Stochastic Green Function (SGF) algorithm is able to simulate any Hamiltonian that does not suffer from the so-called "sign problem". We propose a new global space-time update…
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…
Electrostatic effects and band-bending in doped topological insulators
Dimitrios Galanakis, Tudor D. Stanescu
We investigate the electrostatic effects in doped topological insulators by developing a self consistent scheme for an interacting tight binding model. The presence of bulk carrier…
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.…
Proximity of the Superconducting Dome and the Quantum Critical Point in the Two-Dimensional Hubbard Model
Shu-Xiang Yang, Herbert Fotso, Shi-Quan Su +6
We use the dynamical cluster approximation to understand the proximity of the superconducting dome to the quantum critical point in the two-dimensional Hubbard model. In a BCS form…
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…
