Partial suppression of magnetism in the square lattice SU(3) Hubbard model
Samuel Bird, Sebastian Huber, Jannes Nys
The SU(N) Hubbard model is a natural extension of the SU(2) model. However, even the N=3 case remains poorly understood. We report a substantially new ground-state phase diagram of…
Spectroscopy of two-dimensional interacting lattice electrons using symmetry-aware neural backflow transformations
Imelda Romero, Jannes Nys, Giuseppe Carleo
Neural networks have shown to be a powerful tool to represent the ground state of quantum many-body systems, including fermionic systems. However, efficiently integrating lattice s…
Ab-initio variational wave functions for the time-dependent many-electron Schrödinger equation
Jannes Nys, Gabriel Pescia, Alessandro Sinibaldi +1
Understanding the real-time evolution of many-electron quantum systems is essential for studying dynamical properties in condensed matter, quantum chemistry, and complex materials,…
Variational solutions to fermion-to-qubit mappings in two spatial dimensions
Jannes Nys, Giuseppe Carleo
Through the introduction of auxiliary fermions, or an enlarged spin space, one can map local fermion Hamiltonians onto local spin Hamiltonians, at the expense of introducing a set…
Many-Body Quantum States with Exact Conservation of Non-Abelian and Lattice Symmetries through Variational Monte Carlo
Tom Vieijra, Jannes Nys
Optimization of quantum states using the variational principle has recently seen an upsurge due to developments of increasingly expressive wave functions. In order to improve on th…
Restricted Boltzmann Machines for Quantum States with Nonabelian or Anyonic Symmetries
Tom Vieijra, Corneel Casert, Jannes Nys +4
Although artificial neural networks have recently been proven to provide a promising new framework for constructing quantum many-body wave functions, the parameterization of a quan…
