Topological random alloy
Subrata Pachhal, Aziz Hasan, Adhip Agarwala
Topological phases of matter are often realized in crystalline materials. To extend their understanding beyond perfect stoichiometry, we introduce a minimal model of a topological…
Diffusive metal in a percolating Chern insulator
Subrata Pachhal, Naba P. Nayak, Soumya Bera +1
Two-dimensional non-interacting fermions without any anti-unitary symmetries generically get Anderson localized in the presence of disorder. In contrast, topological superconductor…
Signatures of emergent surface states across a displacive topological phase transition in BiI
Deep Singha Roy, Sk Kalimuddin, Subrata Pachhal +13
Topological phase transitions involving crystalline symmetry breaking provide a fertile ground to explore the interplay between symmetry, topology, and emergent quantum phenomena.…
Symmetry-protected topological wire in a topological vacuum
Subrata Pachhal, Adhip Agarwala
Symmetry-protected topological phases host gapless modes at their boundary with a featureless environment of the same dimension or a trivial vacuum. In this study, we explore their…
Entanglement signatures of a percolating quantum system
Subrata Pachhal, Adhip Agarwala
Entanglement measures have emerged as one of the versatile probes to diagnose quantum phases and their transitions. Universal features in them expand their applicability to a range…
Percolation Transition in a Topological Phase
Saikat Mondal, Subrata Pachhal, Adhip Agarwala
Transition out of a topological phase is typically characterized by discontinuous changes in topological invariants along with bulk gap closings. However, as a clean system is geom…
Spectral Form Factors of Topological Phases
Anurag Sarkar, Subrata Pachhal, Adhip Agarwala +1
Signatures of dynamical quantum phase transitions and chaos can be found in the time evolution of generalized partition functions such as spectral form factors (SFF) and Loschmidt…
