Invited Seminar on Entanglement Structures in Quantum Many-Body Systems
Hiroshi Ueda delivered an invited seminar at the Solid State Physics Seminar (FY2026, 1st Seminar) held at the Graduate School of Engineering Science, The University of Osaka.
The seminar, entitled “Understanding Entanglement Structures in Quantum Many-Body Systems and Their Applications”, reviewed recent developments in tensor-network methods and their applications to quantum many-body physics.
The talk discussed how entanglement structures provide a powerful framework for understanding quantum phases and phase transitions beyond conventional symmetry-breaking paradigms, including topological phases and quantum spin liquids. Recent advances in tensor-network approaches, such as matrix product states and symmetry-based classifications of quantum phases, were also introduced.
The seminar further highlighted emerging quantum–classical hybrid approaches that combine tensor-network techniques with quantum computing, aiming to tackle large-scale and higher-dimensional quantum many-body problems.
The event brought together students and researchers in condensed-matter physics and related fields, fostering interdisciplinary discussions on modern approaches to quantum many-body systems.
Hiroshi Ueda is an Associate Professor at the Center for Quantum Information and Quantum Biology (QIQB), The University of Osaka.
His research focuses on tensor network methods, quantum many-body physics, quantum algorithms, and quantum-classical hybrid computation. He develops theoretical and numerical approaches for understanding quantum many-body systems and for designing quantum algorithms inspired by tensor network structures.
