Phase diagram and crystal melting of helium-4 in two dimensions
David Linteau, Gabriel Pescia, Jannes Nys +2
We study the zero-temperature phase diagram of two-dimensional helium-4 using neural quantum states. Our variational description allows us to address liquid and solid phases using…
Sparse Autoregressive Neural Networks for Classical Spin Systems
Indaco Biazzo, Dian Wu, Giuseppe Carleo
Efficient sampling and approximation of Boltzmann distributions involving large sets of binary variables, or spins, are pivotal in diverse scientific fields even beyond physics. Re…
Unbiased Monte Carlo Cluster Updates with Autoregressive Neural Networks
Dian Wu, Riccardo Rossi, Giuseppe Carleo
Efficient sampling of complex high-dimensional probability distributions is a central task in computational science. Machine learning methods like autoregressive neural networks, u…
Universal Scaling Laws for Correlation Spreading in Quantum Systems with Short- and Long-Range Interactions
Lorenzo Cevolani, Julien Despres, Giuseppe Carleo +2
We study the spreading of information in a wide class of quantum systems, with variable-range interactions. We show that, after a quench, it generally features a double structure,…
Spreading of correlations in exactly-solvable quantum models with long-range interactions in arbitrary dimensions
Lorenzo Cevolani, Giuseppe Carleo, Laurent Sanchez-Palencia
We study the out-of-equilibrium dynamics induced by quantum quenches in quadratic Hamiltonians featuring both short- and long-range interactions. The spreading of correlations in t…
Localization and Glassy Dynamics Of Many-Body Quantum Systems
Giuseppe Carleo, Federico Becca, Marco Schiró +1
When classical systems fail to explore their entire configurational space, intriguing macroscopic phenomena like aging and glass formation may emerge. Also closed quanto-mechanical…
