Fractal hierarchy enables exponential scaling of topological boundary states
Limin Song, Zhichan Hu, Ziteng Wang +7
Exponential growth describes an extremely rapid process ubiquitous across mathematics and diverse physical, biological, and technological systems. Here, we introduce a class of fra…

Unveiling prethermalization and thermal processes through the simplest one-dimensional topological model
Guowen Yang, Jiale Wang, Yichuan Chen +5
Drawing on classical thermodynamic principles-such as the equipartition of energy and entropy maximization-extensive research has shown that the evolution of optical power in multi…

Bulk-hole correspondence and inner robust boundary modes in singular flatband lattices
Limin Song, Shenyi Gao, Shiqi Xia +5
Topological entities based on bulk-boundary correspondence are ubiquitous, from conventional to higher-order topological insulators, where the protected states are typically locali…
