Neural-network solutions to the many-body problem

Artificial neural networks have proven to be a flexible tool to compactly represent quantum many-body states in condensed matter, chemistry, and nuclear physics problems, where non-perturbative interactions are prominent. I will initially illustrate a simple neural-network quantum state ansatz suitable to solve the quantum harmonic oscillator problem.

I will then introduce neural-network architectures employed to solve different quantum many-body systems, both in real space and occupation-number formalism.
Finally, I will present a neural-network ansatz that is specifically designed to model the ground-state wave function of atomic nuclei and infinite neutron matter.

Students are cordially invited
