University Alumnae Predicted Entanglement Entropy in One-Dimensional Fermi-Hubbard Systems

Graduates of the Education and Research Institute “School of Physics and Technology”, Elvira Bilokon and Valeriia Bilokon, who are currently working at Tulane University (USA), in collaboration with colleagues from the University of Arizona (USA) and Karazin University, have predicted entanglement entropy in one-dimensional Fermi-Hubbard systems using machine learning.

Quantum entanglement plays a crucial role in emerging technologies and in our understanding of fundamental interactions, yet its relationship with particle transport remains largely unexplored.

The researchers demonstrated a universal connection between the degree of entanglement and the number of particles that successfully tunnel through a barrier.

The team revealed this connection within a specific particle interaction model, applying a novel machine learning approach to uncover patterns with exceptional accuracy and proposing a simple formula to describe this behavior.

This discovery offers a powerful new framework both for characterizing correlations in various physical systems and for predicting the evolution of entanglement during particle transport — with potential implications for fields such as materials science and quantum computing.

More details about the scientific findings can be found in the journal Quantumzeitgeist.

Congratulations to the team — and best wishes for continued success!
