The Uhlmann phase of Higher-Order Topological Insulators at Finite Temperature
Shiyu Chen, Yan He
We have studied the finite-temperature topology of higher-order topological insulators (HOTIs) based on the Uhlmann phase, which is a phase angle of the Uhlmann overlap. As an exam…

Complex Diophantine Approximations and Cusp Excursions
Nathan Dalaklis, Yan Mary He
We study the Hausdorff dimension spectrum of asymptotic approximation rates of complex Diophantine approximation and that of the asymptotic average excursion time of cusp excursion…
