A New Class of Solutions to the Strong CP Problem with a Small Two-Loop theta
Darwin Chang, Wai-Yee Keung
We present a new class of models which produce zero theta (QCD} angle at the tree and one-loop level due to hermiticity of sub-blocks in the extended quark mass matrices. The struc…

Transplanckian Entanglement Entropy
Darwin Chang, Chong-Sun Chu, Feng-Li Lin
The entanglement entropy of the event horizon is known to be plagued by the UV divergence due to the infinitely blue-shifted near horizon modes. In this paper we calculate the enta…

Potential Flow of Renormalization Group in Quasi-One-Dimensional Systems
Wei Chen, Ming-Shyang Chang, Hsiu-Hau Lin +2
We address the issue why the phase diagrams for quasi-one-dimensional systems are rather simple, while the renormalization group equations behind the scene are non-linear and messy…
