This is the implementation of the variational quantum Monte Carlo to find a ground state in scalar free field theory on a fuzzy sphere and a scalar theory with a quartic interaction. The code is adapted from variational quantum Monte Carlo for mini-BMN matrix models (https://github.com/hanxzh94/matrix-model) with more details at arXiv:1906.08781. See the link to original code for setup.

• ent_scalar.py is used to compute entanglement of the wavefunction for scalar free field theory on a fuzzy sphere for different masses
• ent_quartic.py is used to compute entanglement of the wavefunction for a scalar field theory with a quartic interaction on a fuzzy sphere for different quartic interaction parameter
• obs1d.py includes observables and hamiltonians for scalar free field theory and scalar field theory with a quartic interaction on a fuzzy sphere
• wavefunc.py added wavefunction ansatz for scalar free field theory
• data/ added projection matrices for scalar free field theory
