Topologically protected dynamics in three-dimensional nonlinear antisymmetric Lotka-Volterra systems
Muhammad Umer, Jiangbin Gong
Studies of topological bands and their associated low-dimensional boundary modes have largely focused on linear systems. This work reports robust dynamical features of three-dimens…
Floquet higher-order Weyl and nexus semimetals
Weiwei Zhu, Muhammad Umer, Jiangbin Gong
This work reports the general design and characterization of two exotic, anomalous nonequilibrium topological phases. In equilibrium systems, the Weyl nodes or the crossing points…
Dynamical characterization of Weyl nodes in Floquet Weyl semimetal phases
Muhammad Umer, Raditya Weda Bomantara, Jiangbin Gong
Due to studies in nonequilibrium (periodically-driven) topological matter, it is now understood that some topological invariants used to classify equilibrium states of matter do no…
Counter-propagating edge states in Floquet topological insulating phases
Muhammad Umer, Raditya Weda Bomantara, Jiangbin Gong
Nonequilibrium Floquet topological phases due to periodic driving are known to exhibit rich and interesting features with no static analogs. Various known topological invariants us…
Direct prediction of corner state configurations from edge winding numbers in 2D and 3D chiral-symmetric lattice systems
Linhu Li, Muhammad Umer, Jiangbin Gong
Higher-order topological phases feature topologically protected boundary states in lower dimensions. Specifically, the zero-dimensional corner states are protected by the th-ord…
