Renormalization flows for 1D mixed states and a quantum Goursat lemma
Léo Le-Nestour, David Pérez-GarcÃa, Alberto Ruiz-de-Alarcón
Renormalization provides a framework for relating microscopic models of physical systems to effective descriptions at larger length scales. This procedure is studied for the bounda…
Haag Duality for 2D Quantum Spin Systems
Yoshiko Ogata, David Pérez-GarcÃa, Alberto Ruiz-de-Alarcón
Haag duality is a fundamental locality property introduced in the pioneering formulation of algebraic quantum field theory by Haag and Kastler in the 1960s. Since then, it has play…
Parent Lindbladians for Matrix Product Density Operators
Yuhan Liu, Alberto Ruiz-de-Alarcón, Georgios Styliaris +3
Understanding quantum phases of matter is a fundamental goal in physics. For pure states, the representatives of phases are the ground states of locally interacting Hamiltonians, w…
Conditional Independence of 1D Gibbs States with Applications to Efficient Learning
Ãlvaro M. Alhambra, Ãngela Capel, Paul Gondolf +2
We show that spin chains in thermal equilibrium have a correlation structure in which individual regions are strongly correlated at most with their near vicinity. We quantify this…
