Resonating valence bond pairing energy in graphene by quantum Monte Carlo
S. Azadi, A. Principi, T. D. Kühne +1
We determine the resonating-valence-bond (RVB) state in graphene using real-space quantum Monte Carlo with correlated variational wave functions. Variational and diffusion quantum…
Quantum Monte Carlo description of correlated electrons in two-dimensional FeSe
S. Azadi, A. Principi, R. V. Belosludov +2
An interesting question in physics is how the correlation energy of atoms evolves upon forming a solid. Here, we address this problem for a specific case of double-layer FeSe. We u…
Estimates of the dynamic structure factor for the finite temperature electron liquid via analytic continuation of path integral Monte Carlo data
Thomas Chuna, Nicholas Barnfield, Jan Vorberger +3
Understanding the dynamic properties of the uniform electron gas (UEG) is important for numerous applications ranging from semiconductor physics to exotic warm dense matter. In thi…
Simultaneous Spin and Point-Group Adaptation in Exact Diagonalization of Spin Clusters
Shadan Ghassemi Tabrizi, Thomas D. Kühne
While either spin or point-group adaptation is straightforward when considered independently, the standard technique for factoring isotropic spin Hamiltonians by the total spin S a…
Electron correlation effects and spin-liquid state in the Herbertsmithite Kagome lattice
Sam Azadi, Kühne
We employ real-space variational quantum Monte Carlo methods with resonating valence bond many-body wave functions to investigate electron correlation effects in the Kagome system…
Projective spin adaptation for the exact diagonalization of isotropic spin clusters
Shadan Ghassemi Tabrizi, Thomas D. Kühne
Spin Hamiltonians, like the Heisenberg model, are used to describe magnetic properties of exchange-coupled molecules and solids. For finite clusters, physical quantities such as he…
