Topological corner modes in a brick lattice with nonsymmorphic symmetry
Yuhan Liu, Yuzhu Wang, Nai Chao Hu +3
The quest for new realizations of higher-order topological system has garnered much recent attention. In this work, we propose a paradigmatic brick lattice model where corner modes…
Entangled multi-component 4D quantum Hall states from photonic crystal defects
Xiao Zhang, Youjian Chen, Yuzhu Wang +4
Recently, there has been a drive towards the realization of topological phases beyond conventional electronic materials, including phases defined in more than three dimensions. We…
Non-factorizable 4D quantum Hall state from photonic crystal defects
Xiao Zhang, You Jian Chen, Bochen Guan +3
In the recent years, there has been a drive towards the realization of topological phases beyond conventional electronic materials, including phases defined in more than three dime…
Line nodes, Dirac points and Lifshitz transition in 2D nonsymmorphic photonic crystals
Jun Yu Lin, Nai Chao Hu, You Jian Chen +2
Topological phase transitions, which have fascinated generations of physicists, are always demarcated by gap closures. In this work, we propose very simple 2D photonic crystal latt…
