X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…

Observation of exceptional topology and nonlocal skin effect in Klein bottle electric circuits
Pengtao Lai, Xiangru Chen, Yugan Tang +7
Symmetry and its representation play a crucial role in topological phases, including both Hermitian and non-Hermitian paradigms. In the presence of synthetic gauge field, spatial s…

Real-projective-plane hybrid-order topological insulator realized in phononic crystals
Pengtao Lai, Jien Wu, Zhenhang Pu +7
The manifold of the fundamental domain of the Brillouin zone is always considered to be a torus. However, under the synthetic gauge field, the Brillouin manifold can be modified by…
