/DQMC_project_ATBM

A DQMC project based on the (attractive two-band model---ATBM) Hamiltonian introduced in https://doi.org/10.1103/PhysRevLett.125.247001. First, I reproduce their results finding a Neel state. Later, I choose a Fermi surface which favors a degenerate magnetic ground state, which I investigate with respect of all sorts of bilinear orders.

DQMC_project_ATBM

A DQMC project based on the (attractive two-band model---ATBM) Hamiltonian introduced in https://doi.org/10.1103/PhysRevLett.125.247001. First, in IsingX_Neel I reproduce parts of the paper's results. Later, in IsingX_Striped and Heisenberg_Striped I choose a Fermi surface which favors a degenerate magnetic ground state with $N_\phi=1$ and $N_\phi=3$ bosonic components, respectively. These cases are studied with respect to all sorts of bilinear orders.

The implementation is based on the MonteCarlo.jl package, which I modified slightly.

Research in progress.
