Microwave Imaging of Edge Conductivity in Graphene at Charge Neutrality and Quantum Hall States
Hongtao Yan, Chun-Chih Tseng, Anzhuoer Li +8
We report local conductivity imaging of edge states in monolayer graphene by millikelvin microwave impedance microscopy (MIM). At the charge-neutrality point, as the magnetic field…

Valley Order in Moiré Topological Insulators
Bo Zou, Anzhuoer Li, Allan H. MacDonald
Moiré materials with opposite non-zero miniband Chern numbers in time-reversal-partner valleys are two-dimensional topological insulators at band filling . We explore the po…

Geodynamics and artificial gravity in space-time crystals under slow perturbation and deformation
Anzhuoer Li, Liang Dong, Qian Niu
We present a theory of geodynamics in a space-time crystal based on an event wave packet constructed from the Floquet-Bloch waves, which not only involve a scalar dispersion functi…
