Ideal Weak Topological Insulator and Protected Helical Saddle Points
Ji Seop Oh, Tianyi Xu, Nikhil Dhale +16
The paradigm of classifying three-dimensional (3D) topological insulators into strong and weak ones (STI and WTI) opens the door for the discovery of various topological phases of…
Evidence for Flat Band Dirac Superconductor Originating from Quantum Geometry
Haidong Tian, Shi Che, Tianyi Xu +7
In a flat band superconductor, the charge carriers' group velocity vF is extremely slow, quenching their kinetic energy. The emergence of superconductivity thus appears paradoxical…
Quantum cascade of new correlated phases in trigonally warped bilayer graphene
Anna M. Seiler, Fabian R. Geisenhof, Felix Winterer +5
Divergent density of states offers the unique opportunity to explore a wide variety of correlated electron physics. In the thinnest limit, this has been predicted and verified in t…
Tunable quantum anomalous Hall octet driven by orbital magnetism in bilayer graphene
Fabian R. Geisenhof, Felix Winterer, Anna M. Seiler +4
The quantum anomalous Hall (QAH) effect - a macroscopic manifestation of chiral band topology at zero magnetic field - has only been experimentally realized by magnetic doping of t…
Rational Design of Half-Metallic Heterostructures
William H. Butler, Claudia K. A. Mewes, Chunsheng Liu +1
We present a rational approach to the design of half-metallic heterostructures which allows the design of an infinite number of half-metallic heterostructures. The wide range of ma…
