Topologically shadowed quantum criticality: A non-compact conformal manifold
Tianyao Fang, Weicheng Ye, Zhengcheng Gu +1
We put forward a proposal for topological quantum critical points (tQCPs) separating non-invertible chiral topological orders in dimensions. We conjecture that these tQCPs…

Constraining Ultra-Light Dark Matter mass with Dwarf Galaxy Rotation Curves
Tian-yao Fang, Ming-Chung Chu
While ultra-light bosonic dark matter (ULDM) in a Bose-Einstein condensate (BEC) state could naturally account for the central core in some galaxies and resolve the core-cusp probl…

The emergence of Einstein gravity from topological supergravity in D
Tianyao Fang, Zheng-Cheng Gu
The topological aspects of Einstein gravity suggest that topological invariance could be a more profound principle in understanding quantum gravity. In this work, we explore a topo…
