Layer-Resolved Topological Metals in the Bilayer Lieb Lattice
Mengjie Yang, S Rahul, Giandomenico Palumbo
We identify a two-dimensional time-reversal-invariant topological metallic phase on a bilayer Lieb lattice, characterized by a quantized layer--resolved pseudo-spin Chern number. W…
Unconventional quantum criticality in a non-Hermitian extended Kitaev chain
S Rahul, Nilanjan Roy, Ranjith R Kumar +2
We investigate the nature of quantum criticality and topological phase transitions near the critical lines obtained for the extended Kitaev chain with next nearest neighbor hopping…
Signatures of topological phase transition on a quantum critical line
Ranjith R Kumar, Nilanjan Roy, Y R Kartik +2
Recently topological states of matter have witnessed a new physical phenomenon where both edge modes and gapless bulk coexist at topological quantum criticality. The presence and a…
A study of topological characterization and symmetries for a quantum simulated Kitaev chain
Y R Kartik, Ranjith R Kumar, S Rahul +1
An attempt is made to quantum simulate the topological classification, such as winding number, geometric phase and symmetry properties for a quantum simulated Kitaev chain. We find…
