This workshop is an interdisciplinary meeting focusing on new formulations related to lattice fermions, bringing together researchers across particle physics, nuclear physics, condensed matter physics, and mathematics. Participant registration will open soon. For now, we would appreciate it if you could save the dates. We very much look forward to your participation. Sincerely, Etsuko Itou on behalf of the organizers ------------------------------------------------------------------------------------------ YITP workshop “Frontiers of Lattice Fermions” Dates: June 29 (Mon) – July 3 (Fri), 2026 Venue: Panasonic Hall, Kyoto University Workshop website: https://indico.yukawa.kyoto-u.ac.jp/event/78/ Overview In recent years, alongside advances in the theoretical understanding of lattice gauge theories in the Hamiltonian formulation and of anomalies, active research has been carried out on new formulations of lattice fermions from the perspectives of particle physics, condensed matter physics, and mathematics. This workshop brings together researchers from these typically separate communities to promote close discussions of recent developments and to stimulate new conceptual and technical progress. Formulations of lattice fermions are constrained by the well-known Nielsen–Ninomiya theorem, which prohibits the realization of chiral fermions on the lattice under conditions such as translational invariance and locality. Nevertheless, in recent years, new approaches to lattice fermions that evade this constraint, as well as renewed studies of chiral anomalies, have been actively explored from various viewpoints. This workshop aims to provide an overview of these developments, clarify the current status and open issues in lattice fermion and anomaly of gauge theories research centered on the Hamiltonian formulation, and foster interactions across disciplines in order to generate new research directions.
