Kagome lattice flat band
WebbExamples of laser-written and engineered flat-band photonic lattices. (A) A photonic Lieb lattice established by fs-laser-writing technique for demonstration of flat-band compact … WebbGround-state configurations are obtained by means of the annealing procedure and their stability is additionally studied by the normal modes analysis. While commonly the square lattice is mechanically unstable due to softening of the shear modulus, we were able to find a specific set of parameters for which the square lattice can be made stable.
