Intrinsic nonreciprocal bulk plasmons in noncentrosymmetric magnetic systems
Debasis Dutta, Atasi Chakraborty, Amit Agarwal
Nonreciprocal plasmonics enables one-way light propagation at the nanoscale and it is an essential building block for photonics applications. Here, we explore intrinsic nonreciproc…
Nonlinear anomalous Hall effects probe topological phase-transitions in twisted double bilayer graphene
Atasi Chakraborty, Kamal Das, Subhajit Sinha +3
Nonlinear anomalous Hall effect is the Berry curvature dipole induced second-order Hall voltage or temperature difference in response to a longitudinal electric field or temperatur…
Tunable interband and intraband plasmons in twisted double bilayer graphene
Atasi Chakraborty, Debasis Dutta, Amit Agarwal
Flat bands in twisted moire superlattices support a variety of topological and strongly correlated phenomena along with easily tunable electrical and optical properties. Here, we d…
Berry curvature dipole senses topological transition in a moiré superlattice
Subhajit Sinha, Pratap Chandra Adak, Atasi Chakraborty +8
Topological aspects of electron wavefunction play a crucial role in determining the physical properties of materials. Berry curvature and Chern number are used to define the topolo…
