Coexistence of strong nematic and superconducting correlations in a two-dimensional Hubbard model
Shi-Quan Su, Thomas A. Maier
Using a dynamic cluster quantum Monte Carlo approximation, we study a two-dimensional Hubbard model with a small orthorhombic distortion in the nearest neighbor hopping integrals.…
The response to dynamical modulation of the optical lattice for fermions in the Hubbard model
Zhaoxin Xu, Simone Chiesa, Shuxiang Yang +5
Fermionic atoms in a periodic optical lattice provide a realization of the single-band Hubbard model. Using Quantum Monte Carlo simulations along with the Maximum Entropy Method, w…
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…
Dynamical Cluster Quantum Monte Carlo Study of the Single Particle Spectra of Strongly Interacting Fermion Gases
Shi-Quan Su, Daniel E. Sheehy, Juana Moreno +1
We study the single-particle spectral function of resonantly-interacting fermions in the unitary regime, as described by the three-dimensional attractive Hubbard model in the dilut…
Evolution of pairing from weak to strong coupling on a honeycomb lattice
Shi-Quan Su, Ka-Ming Tam, Hai-Qing Lin
We study the evolution of the pairing from weak to strong coupling on a honeycomb lattice by Quantum Monte Carlo. We show numerical evidence of the BCS-BEC crossover as the couplin…
