Chiral metals and entrapped insulators in a one-dimensional topological non-Hermitian system
Ayan Banerjee, Suraj S. Hegde, Adhip Agarwala +1
In this work we study many-body 'steady states' that arise in the non-Hermitian generalisation of the non-interacting Su-Schrieffer-Heeger model at a finite density of fermions. We…
Interaction driven giant thermopower in magic-angle twisted bilayer graphene
Arup Kumar Paul, Ayan Ghosh, Souvik Chakraborty +9
Magic-angle twisted bilayer graphene (MtBLG) has proven to be an extremely promising new platform to realize and study a host of emergent quantum phases arising from the strong cor…
Exploring ideas in topological quantum phenomena: A journey through the SSH model
Anantha Hegde, Adarsh Kumar, Adhip Agarwala +1
Geared as an invitation for undergraduates, beginning graduate students, we present a pedagogical introduction to one-dimensional topological phases -- in particular the Su-Schrief…
Phases and Quantum Phase Transitions in Anisotropic Antiferromagnetic Kitaev-Heisenberg- magnet
Animesh Nanda, Adhip Agarwala, Subhro Bhattacharjee
We study the Kitaev-Heisenberg- model with antiferromagnetic Kitaev exchanges in the strong anisotropic (toric code) limit to understand the phases and the intervening phase tra…
