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…

Matrix product state classification of 1D multipole symmetry protected topological phases
Takuma Saito, Weiguang Cao, Bo Han +1
Spatially modulated symmetries are one of the new types of symmetries whose symmetry actions are position dependent. Yet exotic phases resulting from these spatially modulated symm…

Thermal Hall effects due to topological spin fluctuations in YMnO
Ha-Leem Kim, Takuma Saito, Heejun Yang +7
The thermal Hall effect in magnetic insulators has been considered a powerful method for examining the topological nature of charge-neutral quasiparticles such as magnons. Yet, unl…
