Hybrid Hamiltonian-diagrammatic quantum impurity solver
Yang Yu, Gaurav Harsha, Lei Zhang +4
Quantum impurity models, which describe the coupling between interacting orbitals and a non-interacting bath, play a central role in the physics of strongly correlated electron sys…
Excitations and spectra from equilibrium real-time Green's functions
Xinyang Dong, Emanuel Gull, Hugo U. R. Strand
The real-time contour formalism for Green's functions provides time-dependent information of quantum many-body systems. In practice, the long-time simulation of systems with a wide…
Mechanism of Superconductivity in the Hubbard Model at Intermediate Interaction Strength
Xinyang Dong, Lorenzo Del Re, Alessandro Toschi +1
We study the fluctuations responsible for pairing in the -wave superconducting state of the two-dimensional Hubbard model at intermediate coupling within a cluster dynamical mea…
Quantifying the role of antiferromagnetic fluctuations in the superconductivity of the doped Hubbard model
Xinyang Dong, Emanuel Gull, Andrew. J. Millis
We study the contribution of the electron-spin fluctuation coupling to the superconducting state of the two dimensional Hubbard model within dynamical cluster approximation (DCA) u…
