Observation of Non-Hermitian Spectral Deformation in Complex Momentum Space
Mu Yang, Yue Li, Mingtao Xu +4
Open systems feature a variety of phenomena that arise from non-Hermitian physics. Recent theoretical studies have offered much insights into these phenomena through the non-Bloch…

Optimal spectral transport of non-Hermitian systems
Mingtao Xu, Zongping Gong, Wei Yi
The optimal transport problem seeks to minimize the total transportation cost between two distributions, thus providing a measure of distance between them. In this work, we study t…

Characterizing the Yang-Lee zeros of the classical Ising model through dynamic quantum phase transitions
Mingtao Xu, Wei Yi, De-Huan Cai
In quantum dynamics, the Loschmidt amplitude is analogous to the partition function in the canonical ensemble. Zeros in the partition function indicate a phase transition, while th…
