Generation of higher-order topological insulators using periodic driving
Arnob Kumar Ghosh, Tanay Nag, Arijit Saha
Topological insulators~(TIs) are a new class of materials that resemble ordinary band insulators in terms of a bulk band gap but exhibit protected metallic states on their boundari…
Floquet second-order topological Anderson insulator hosting corner localized modes
Arnob Kumar Ghosh, Tanay Nag, Arijit Saha
The presence of random disorder in a metallic system accounts for the localization of extended states in general. On the contrary, the presence of disorder can induce topological p…
Fano resonances in tilted Weyl semimetals in an oscillating quantum well
Souvik Das, Arnab Maity, Rajib Sarkar +3
Considering the low-energy model of tilted Weyl semimetal, we study the electronic transmission through a periodically driven quantum well, oriented in the transverse direction wit…
Topological characterization of special edge modes from the winding of relative phase
Sudarshan Saha, Tanay Nag, Saptarshi Mandal
The symmetry-constrained topological invariant fails to explain the emergence of the special edge modes when system does not preserve discrete symmetries. The inversion or chiral s…
Fano resonances for tilted linear and quadratic band touching dispersions in a harmonically driven potential well
Anton Gregefalk, Annica Black-Schaffer, Tanay Nag
Considering models with tilted linear and quadratic band touching dispersions, we analyze the effect of the transverse linear tilt on the transmission spectra through a harmonicall…
Distinct quasiparticle interference patterns for surface impurity scattering on various Weyl semimetals
Feng Xiong, Chaocheng He, Yong Liu +2
We examine the response of the Fermi arc in the context of quasi-particle interference (QPI) with regard to a localized surface impurity on various three-dimensional Weyl semimetal…
