Detection of topological phases by quasi-local operators
Wing Chi Yu, P. D. Sacramento, Yan Chao Li +2
It has been proposed recently by some of the authors that the quantum phase transition of a topological insulator like the SSH model may be detected by the eigenvalues and eigenvec…
Discrete time crystal in globally driven interacting quantum systems without disorder
Wing Chi Yu, Jirawat Tangpanitanon, Alexander W. Glaetzle +2
Time crystals in periodically driven systems have initially been studied assuming either the ability to quench the Hamiltonian between different many-body regimes, the presence of…
Nonsymmorphic cubic Dirac point and crossed nodal rings across the ferroelectric phase transition in LiOsO
Wing Chi Yu, Xiaoting Zhou, Feng-Chuan Chuang +3
Crystalline symmetries can generate exotic band-crossing features, which can lead to unconventional fermionic excitations with interesting physical properties. We show how a cubic…
