Flat band in twisted bilayer Bravais lattices
Band engineering in twisted bilayers of the five generic two-dimensional Bravais networks is demonstrated. We first derive constraints on the interlayer coupling that determines an effective potential for low-energy physics. The constraints are originated from symmetry and fixed without reference to...
