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…

Quantum Valley Hall effect without Berry curvature
Rasoul Ghadimi, Chiranjit Mondal, Sunje Kim +1
The quantum valley Hall effect (QVHE) is characterized by the valley Chern number (VCN) in a way that one-dimensional (1D) chiral metallic states are guaranteed to appear at the do…
