Skyrmion stripes in twisted double bilayer graphene
Debasmita Giri, Dibya Kanti Mukherjee, H. A. Fertig +1
Two dimensional moiré systems have recently emerged as a platform in which the interplay between topology and strong correlations of electrons play out in non-trivial ways. Among t…
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…
Lorentz-boost-driven magneto-optics in a Dirac nodal-line semimetal
J. Wyzula, X. Lu, D. Santos-Cottin +13
Optical response of crystalline solids is to a large extent driven by excitations that promote electrons among individual bands. This allows one to apply optical and magneto-optica…
Surface plasmonics of Weyl semimetals
Xin Lu, Dibya Kanti Mukherjee, Mark O. Goerbig
Smooth interfaces of topological systems are known to host massive surface states along with the topologically protected chiral one. We show that in Weyl semimetals these massive s…
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…
Dynamical conductivity of the Fermi arc and the Volkov-Pankratov states on the surface of Weyl semimetals
Dibya Kanti Mukherjee, David Carpentier, Mark Oliver Goerbig
Weyl semimetals are known to host massless surface states called Fermi arcs. These Fermi arcs are the manifestation of the bulk-edge correspondence in topological matter and thus a…
Spin Response and Collective Modes in Simple Metal Dichalcogenides
Dibya Kanti Mukherjee, Arijit Kundu, H. A. Fertig
Transition metal dichalcogenide (TMD) monolayers are interesting materials in part because of their strong spin-orbit coupling. This leads to intrinsic spin-splitting of opposite s…
Fabry-Perot interferometry in Weyl semi-metals
Dibya Kanti Mukherjee, Sumathi Rao, Sourin Das
We show that the electrical transport across a minimal model for a time-reversal symmetry(TRS) breaking Weyl semi-metal (WSM) involving two Weyl nodes can be interpreted as an inte…
Transport through Andreev bound states in a Weyl semimetal quantum dot
Dibya Kanti Mukherjee, Sumathi Rao, Arijit Kundu
We study transport through a Weyl semimetal quantum dot sandwiched between an -wave superconductor and a normal lead. The conductance peaks at regular intervals and exhibits dou…
Spin-dependent Andreev reflection in spin-orbit coupled systems by breaking time-reversal symmetry
Dibya Kanti Mukherjee, Joanna Hutchinson, Arijit Kundu
We study theoretically the differential conductance at a junction between a time reversal symmetry broken spin orbit coupled system with a tunable band gap and a superconductor. We…
Chiral nodes and oscillations in the Josephson current in Weyl semimetals
Udit Khanna, Dibya Kanti Mukherjee, Arijit Kundu +1
The separation of the Weyl nodes in a broken time-reversal symmetric Weyl semimetal leads to helical quasi-particle excitations at the Weyl nodes, which, when coupled with overall…
