protected from internal perturbation of site-to-site couplings.Our demonstration of a non-Hermitian topological structure with an EP paves the way for the development of novel sensors that are not sensitive to internal manufacturing errors but are highly sensitive to changes in the external ...
A mathematical structure composed of three topological spaces (total space, base space and fibres) and a projection map. The fibres adhere to the base space and their product space further gives the total space by the projection map, a continuous surjection satisfying a local triviality condition...

Spin–orbit coupling is an essential mechanism underlying quantum phenomena such as the spin Hall effect and topological insulators1. It has been widely studied in well-isolated Hermitian systems, but much less is known about the role dissipation plays in spin–orbit-coupled systems2. Here we impl...
Simultaneous occurrence of the conventionally incompatible critical Landau‐class transition and topological‐class transition is realized, with conceptional renovation and more potential of applications in designing quantum sensors. 展开 关键词: critical quantum metrology jaynes‐cummings model light‐matter ...
