Non-invertible translation from Lieb-Schultz-Mattis anomaly
Tsubasa Oishi, Takuma Saito, Hiromi Ebisu
Symmetry provides powerful non-perturbative constraints in quantum many-body systems. A prominent example is the Lieb-Schultz-Mattis (LSM) anomaly -- a mixed 't Hooft anomaly betwe…

Type-IV 't Hooft Anomalies on the Lattice: Emergent Higher-Categorical Symmetries and Applications to LSM Systems
Tsubasa Oishi, Hiromi Ebisu
't Hooft anomalies impose fundamental constraints on quantum matter and often lead to emergent symmetry structures upon gauging. We analyze a lattice model with four global symmetr…

-ality symmetry and SPT phases in (1+1)d
Jun Maeda, Tsubasa Oishi
Duality symmetries have been extensively investigated in various contexts, playing a crucial role in understanding quantum field theory and condensed matter theory. In this paper,…
