Topologically nontrivial multicritical points

Ranjith R Kumar, Pasquale Marra

Recently, the intriguing interplay between topology and quantum criticality has been unveiled in one-dimensional topological chains with extended nearest-neighbor couplings. In the…

Topological transition between gapless phases in quantum walks

Ranjith R Kumar, Hideaki Obuse

Topological gapless phases of matter have been a recent interest among theoretical and experimental condensed matter physicists. Fermionic chains with extended nearest neighbor cou…
