Author(s): Xu-Yang Hou, Xin Wang, and Hao Guo Geometric phases play a fundamental role in understanding the geometric structure of quantum states, yet extending the Uhlmann phase to non-Hermitian systems poses significant challenges due to parameter-dependent inner product structures. In this work, we develop a comprehensive theory of the Uhlma… [Phys. Rev. B 114, 084106] Published Fri Aug 14, 2026
