Embedding independent length scale of flat bands
Seokju Lee, Seung Hun Lee, Bohm-Jung Yang
In flat-band systems with quenched kinetic energy, most of the conventional length scales related to the band dispersion become ineffectual. Although a few geometric length scales,…

Non-Abelian charge conversion in bilayer binary honeycomb lattice systems
Chiranjit Mondal, Rasoul Ghadimi, Bohm-Jung Yang
In two-dimensional systems with space-time inversion symmetry, Dirac nodes (DNs) carry non-Abelian topological charges which induce intriguing momentum space braiding phenomenon. A…
