Transition between 2D Symmetry Protected Topological Phases on a Klein Bottle
Vibhu Ravindran, Bowen Yang, Xie Chen
Manifolds with nontrivial topology play an essential role in the study of topological phases of matter. In this paper, we study the nontrivial symmetry response of the D …

Witt Groups and Bulk-Boundary Correspondence for Stabilizer States
BÅażej Ruba, Bowen Yang
We establish a bulk--boundary correspondence for translation-invariant stabilizer states in arbitrary spatial dimension, formulated in the framework of modules over Laurent polynom…

GeoPE:A Unified Geometric Positional Embedding for Structured Tensors
Yupu Yao, Bowen Yang
Standard Vision Transformers flatten 2D images into 1D sequences, disrupting the natural spatial topology. While Rotary Positional Embedding (RoPE) excels in 1D, it inherits this l…
