Spectroscopic evidence for a spin and valley polarized metallic state in a non-magic-angle twisted bilayer graphene
Ya-Ning Ren, Chen Lu, Yu Zhang +7
In the magic-angle twisted bilayer graphene (MA-TBG), strong electron-electron (e-e) correlations caused by the band-flattening lead to many exotic quantum phases such as supercond…

Intrinsic topological superconductivity with exactly flat surface bands in the quasi-one-dimensional ACrAs (A=Na, K, Rb, Cs) superconductors
Cheng-Cheng Liu, Chen Lu, Li-Da Zhang +3
A spin-U(1)-symmetry protected momentum-dependent integer--valued topological invariant is proposed to time-reversal-invariant (TRI) superconductivity (SC) whose nonzero value w…
