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…
Fourier nonuniqueness sets for the hyperbola and the Perron-Frobenius operators
Deb Kumar Giri
Let be a smooth curve or finite disjoint union of smooth curves in the plane and be any subset of the plane. Let be the space of all finite complex-valued B…
Heisenberg uniqueness pairs for the hyperbola
Deb Kumar Giri, Rama Rawat
Let be the hyperbola and be the lattice-cross defined by in…
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…
Uniqueness of the Fourier transform on the Euclidean motion group
A. Chattopadhyay, D. K. Giri, R. K. Srivastava
In this article, we prove that if the Fourier transform of a certain integrable function on the Euclidean motion group is of finite rank, then the function has to vanish identicall…
Uniqueness of the group Fourier transform on certain nilpotent Lie groups
A. Chattopadhyay, D. K. Giri, R. K. Srivastava
In this article, we prove that if the group Fourier transform of certain integrable functions on the Heisenberg motion group (or step two nilpotent Lie groups) is of finite rank, t…
Heisenberg uniqueness pairs for some algebraic curves and surfaces
Deb Kumar Giri, R. K. Srivastava
Let be the space of all finite Borel measure in which is supported on the curve and absolutely continuous with respect to the arc length of . For $Λ…
Heisenberg uniqueness pairs for some algebraic curves in the plane
Deb Kumar Giri, R. K. Srivastava
A Heisenberg uniqueness pair is a pair , where is a curve and is a set in such that whenever a finite Borel measure having support on $…
