Solution to the sign problem in a frustrated quantum impurity model
Connor T. Hann, Emilie Huffman, Shailesh Chandrasekharan
In this work we solve the sign problem of a frustrated quantum impurity model consisting of three quantum spin-half chains interacting through an anti-ferromagnetic Heisenberg inte…
Local growth of icosahedral quasicrystalline tilings
Connor Hann, Joshua E. S. Socolar, Paul J. Steinhardt
Icosahedral quasicrystals (IQCs) with extremely high degrees of translational order have been produced in the laboratory and found in naturally occurring minerals, yet questions re…
Ab Initio Quantum Monte Carlo Simulations of the Uniform Electron Gas without Fixed Nodes II: Unpolarized Case
T. Dornheim, S. Groth, T. Schoof +2
In a recent publication [S. Groth \textit{et al.}, PRB (2016)], we have shown that the combination of two novel complementary quantum Monte Carlo approaches, namely configuration p…
