Grokking phase transitions in learning local rules with gradient descent
Bojan Žunkovič, Enej Ilievski
We discuss two solvable grokking (generalisation beyond overfitting) models in a rule learning scenario. We show that grokking is a phase transition and find exact analytic express…
Deep tensor networks with matrix product operators
Bojan Žunkovič
We introduce deep tensor networks, which are exponentially wide neural networks based on the tensor network representation of the weight matrices. We evaluate the proposed method o…
Dynamical Phase Diagram of a Quantum Ising Chain with Long Range Interactions
Giulia Piccitto, Bojan Žunkovič, Alessandro Silva
We investigate the effect of short-range correlations on the dynamical phase diagram of quantum many-body systems with long-range interactions. Focusing on Ising spin chains with p…
Quasi-localized excitations induced by long-range interactions in translationally-invariant quantum spin chains
Alessio Lerose, Bojan Zunkovic, Alessandro Silva +1
We show that long-range ferromagnetic interactions in quantum spin chains can induce spatial quasi-localization of topological magnetic defects, i.e., domain-walls, even in the abs…
Impact of non-equilibrium fluctuations on pre-thermal dynamical phase transitions in long-range interacting spin chains
Alessio Lerose, Bojan Zunkovic, Jamir Marino +2
We study the non-equilibrium phase diagram and the dynamical phase transitions occurring during the pre-thermalization of non-integrable quantum spin chains, subject to either quan…
