Analytical classification of Majorana zero-mode spatial profiles in extended Kitaev chains: probability maxima can shift inward
Vijay Pathak, Vaishnav Mallya, Sujit Sarkar
Topological phases in one-dimensional superconducting systems are commonly characterized by symmetry-protected invariants. These invariants determine the number of Majorana zero-en…
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…
Multi-criticality and long-range effects in non-Hermitian topological models
Y R Kartik, Sujit Sarkar
Long-range effects induce some interesting behavior and considered as a gateway to understand the non-local behavior in the quantum systems. Especially, the long-range topological…
Topological phase transition between non-high symmetry critical phases and curvature function renormalization group
Ranjith R Kumar, Y R Kartik, Sujit Sarkar
The interplay between topology and criticality has been a recent interest of study in condensed matter physics. A unique topological transition between certain critical phases has…
Physics of emergence beyond Berezinskii-Kosterlitz-Thouless transition for interacting topological quantum matter
Ranjith R Kumar, Sujit Sarkar
An attempt is made to find different emergent quantum phases for interacting topological state of quantum matter. Our study is based on the quantum field theoretical renormalizatio…
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…
