Perpendicular electric field drives Chern transitions and layer polarization changes in Hofstadter bands
Pratap Chandra Adak, Subhajit Sinha, Debasmita Giri +10
Moiré superlattices engineer band properties and enable observation of fractal energy spectra of Hofstadter butterfly. Recently, correlated-electron physics hosted by flat bands in…
Plasmon in Nonsymmorphic Dirac semimetals
Debasmita Giri, Arijit Kundu
We study the collective charge-density modes (plasmons) of two-dimensional nonsymmorphic Dirac semimetals, within the random-phase approximation (RPA) in presence of Coulomb intera…
Dipolar optical plasmon in thin-film Weyl semimetals
Debasmita Giri, Dibya Kanti Mukherjee, Sonu Verma +2
In a slab geometry with large surface-to-bulk ratio, topological surface states such as Fermi arcs for Weyl or Dirac semimetals may dominate their low-energy properties. We investi…
RKKY coupling in Weyl semimetal thin films
Sonu Verma, Debasmita Giri, H. A. Fertig +1
We consider the effective coupling between impurity spins on surfaces of a thin-film Weyl semimetal within Ruderman-Kittel-Kasuya-Yoshida (RKKY) theory. If the spins are on the sam…
