Short-range charge fluctuations in the two-dimensional Hubbard model

Xinyang Dong, Emanuel Gull

We investigate charge fluctuations in the two-dimensional Hubbard model as a function of doping, interaction strength, next-nearest-neighbor hopping, and temperature within the eig…

Legendre-spectral Dyson equation solver with super-exponential convergence

Xinyang Dong, Dominika Zgid, Emanuel Gull +1

Quantum many-body systems in thermal equilibrium can be described by the imaginary time Green's function formalism. However, the treatment of large molecular or solid ab inito prob…

The Hartree equation with a constant magnetic field: Well-posedness theory

Xin Dong

We consider the Hartree equation for infinitely many electrons with a constant external magnetic field. For the system, we show a local well-posedness result when the initial data…

Dynamical Charge Susceptibility in the Hubbard Model

Xinyang Dong, Xi Chen, Emanuel Gull

We compute the dynamical charge susceptibility in the two-dimensional Hubbard model within the dynamical cluster approximation. In order to understand the connection between charge…

Stabilizing the spiral order with spin-orbit coupling in an anisotropic triangular antiferromagnet

Xiao-Yong Feng, Xin Dong, Jianhui Dai

We study the effects of spin-orbit coupling (SOC) on the large-U Hubbard model on anisotropic triangular lattice at half-filling using the Schwinger-boson method. We find that the…
