Gull named APS Fellow
Emanuel Gull has been elected a Fellow of the American Physical Society, on the nomination of the APS Division of Computational Physics. The fellowship recognizes his development of numerical methods for the study of strongly correlated electron systems, including quantum impurity solvers, and their application to correlated materials. As announced by the Faculty of Physics of the University of Warsaw, Dominika Zgid was elected a Fellow in the same year, for fundamental contributions to accurate ab initio computational methods for many-body systems in molecules and solids. Both hold ERC Advanced Grants at the University of Warsaw.

ALPS Reaches Version 3.0.0
The ALPS (Algorithms and Libraries for Physics Simulations) project has released version 3.0.0, a major milestone that comes as the project transitions from a single-group effort into a broader collaborative ecosystem under the NSF POSE Phase II award. The release modernizes the project’s build system and documentation, and lays the groundwork for the governance structures and community contributions planned over the course of the award. ALPS provides standardized, well-tested implementations of quantum Monte Carlo, exact diagonalization, DMRG, and DMFT algorithms for strongly correlated quantum lattice models.
GREEN Reaches Version 1.0.0
The Green open source software framework for self-consistent finite-temperature many-body perturbation theory has reached its 1.0.0 release. Green implements the GW and GF2 approximations for molecules and periodic solids using Gaussian basis sets, with support for diagrammatic embedding methods, and is designed for high-performance computing environments targeting ab initio electronic structure of real materials.
Congratulations to Lei Zhang and Yang Yu
Congratulations to Lei Zhang and Yang Yu on successfully completing their PhDs at the University of Michigan. Lei Zhang goes on to the group of Tom Devereaux at Stanford, and Yang Yu joins the group of Karsten Held in Vienna. We wish them both all the best.
NSF POSE Phase II Award: ALPS Ecosystem
The NSF has awarded a Phase II POSE (Pathways to Enable Open-Source Ecosystems) grant to a collaboration led by Vito Scarola (Virginia Polytechnic Institute and State University) to expand and sustain the open-source ALPS (Algorithms and Libraries for Physics Simulations) ecosystem. The $1,490,730 award runs from June 2026 through May 2028 and will transition ALPS from a single-group effort into a broad collaborative community, adding governance structures, training programs, and improved documentation. The Gull group is a partner in this initiative and will contribute to both ALPS and ALPSCore.
ARPA-E Award: Rare-Earth-Free Quantum Magnetism
The Gull group is a partner in a $3.9M ARPA-E award led by Alice & Bob, together with Los Alamos National Laboratory and GE Vernova’s Advanced Research accelerator. The three-year project aims to use quantum computing to discover high-performance permanent magnets that do not rely on rare-earth elements — addressing a critical vulnerability in the supply chains for clean energy and industrial technologies. The Gull group contributes classical many-body algorithms designed to work alongside quantum algorithms, bridging the two approaches for realistic materials calculations.
IEEE Spectrum: Quantum Computers Hunt Rare-Earth-Free Magnets
IEEE Spectrum covers the challenge of designing rare-earth-free permanent magnets — and why quantum computing may be the key to cracking it. Over 67,000 magnetic compounds exist, yet none surpass the performance of neodymium-iron-boron magnets, whose supply chain is concentrated in China. The Alice & Bob–led collaboration, which includes the Gull group, is using quantum computers to navigate this combinatorially vast search space, exploiting superposition and entanglement to simulate electron behavior across crystal lattices that classical computers cannot handle at scale.
ERC Advanced Grant: Quantum Algorithms
The Gull group has been awarded an ERC Advanced Grant for the project Quantum Algorithms, supporting research on quantum computing and many-body simulation methods at the University of Warsaw.
Undergraduate Proposes Solution to Quantum Field Theory Problem
University of Michigan undergraduate Jiani Fei proposed a solution to a long-standing problem in quantum simulation: how to accurately convert calculations performed in imaginary time into real, measurable quantities. Working with Emanuel Gull, Fei showed that Nevanlinna functions — named after Finnish mathematician Rolf Nevanlinna’s 1925 theory — guarantee the conversion process is always causal, dramatically sharpening the resolution of spectral features near the Fermi energy that were previously inaccessible. The work, published in Physical Review Letters, applies across quantum field theories from lattice QCD to superconductors, and connects to fields as distant as industrial control theory.
