Berry Curvature Spectroscopy from Bloch Oscillations
Christophe De Beule, E. J. Mele
Artificial crystals such as moiré superlattices can have a real-space periodicity much larger than the underlying atomic scale. This facilitates the presence of Bloch oscillations…
Roses in the Nonperturbative Current Response of Artificial Crystals
Christophe De Beule, Vo Tien Phong, E. J. Mele
In two-dimensional artificial crystals with large real-space periodicity, the nonlinear current response to a large applied electric field can feature a strong angular dependence,…
Localized states coupled to a network of chiral modes in minimally twisted bilayer graphene
P. Wittig, F. Dominguez, C. De Beule +1
Minimally twisted bilayer graphene in the presence of an interlayer bias develops a triangular network of valley chiral modes that propagate along the interfaces and scatte…
Topological Andreev Rectification
Pok Man Tam, Christophe De Beule, Charles L. Kane
We develop the theory of an Andreev junction, which provides a method to probe the intrinsic topology of the Fermi sea of a two-dimensional electron gas (2DEG). An Andreev junction…
