Quantum simulation of spin-1/2 XYZ model using solid-state spin centers
Troy Losey, Denis R. Candido, Jin Zhang +3
In this work we propose a novel solid-state platform for creating quantum simulators based on implanted spin centers in semiconductors. We show that under the presence of an extern…
Critical Entanglement for the Half-Filled Extended Hubbard Model
Jon Spalding, Shan-Wen Tsai, David K Campbell
We study the ground state of the one-dimensional extended Hubbard model at half-filling using the entanglement entropy calculated by Density Matrix Renormalization Group (DMRG) tec…
Dominant Superconducting Fluctuations in the One-Dimensional Extended Holstein-Extended Hubbard model
Ka-Ming Tam, Shan-Wen Tsai, D. K. Campbell
The search for realistic one-dimensional (1D) models that exhibit dominant superconducting (SC) fluctuations effects has a long history. In these 1D systems, the effects of commens…
Correlated Phases of Population Imbalanced Fermi-Fermi Mixtures on an Optical Lattice
Chen-Yen Lai, Chuntai Shi, Shan-Wen Tsai
We study a two species fermion mixture with different populations on a square lattice modeled by a Hubbard Hamiltonian with on-site inter-species repulsive interaction. Such a mode…
Theory of Scanning Tunneling Spectroscopy of Magnetic Adatoms in Graphene
Bruno Uchoa, Ling Yang, S. -W. Tsai +2
We examine theoretically the signatures of magnetic adatoms in graphene probed by scanning tunneling spectroscopy (STS). When the adatom hybridizes equally with the two graphene su…
Renormalization group approach to anisotropic superconductivity
Rafael Roldan, Shan-Wen Tsai, M. Pilar Lopez-Sancho
The superconducting instability of the Fermi liquid state is investigated by considering anisotropic electron-boson couplings. Both electron-electron interactions and anisotropic e…
