Efficient Calculation of the Maximal Rényi Divergence for a Matrix Product State via Generalized Eigenvalue Density Matrix Renormalization Group
Uri Levin, Noa Feldman, Moshe Goldstein
The study of quantum and classical correlations between subsystems is fundamental to understanding many-body physics. In quantum information theory, the quantum mutual information,…

Entanglement corner dependence in two-dimensional systems: A tensor network perspective
Noa Feldman, Moshe Goldstein
In continuous quantum field theories, the entanglement entropy of a subsystem with sharp corners on its boundary exhibits a universal corner-dependent contribution. We study this c…

Superselection-Resolved Entanglement in Lattice Gauge Theories: A Tensor Network Approach
Noa Feldman, Johannes Knaute, Erez Zohar +1
Lattice gauge theories (LGT) play a central role in modern physics, providing insights into high-energy physics, condensed matter physics, and quantum computation. Due to the nontr…
