Plasmon modes in three-dimensional multifold semimetals. I. Triple-point semimetal, its quadratic cousin, and Hopf semimetal
Ipsita Mandal
We study collective charge excitations in pseudospin-1 triple-point semimetals within the random-phase approximation, considering both the linearised model with a flat-band and its…

Ipsita Mandal
We investigate collective charge excitations in three-dimensional semimetals with dipole-like Berry-curvature (BC) profiles, focusing on vortex nodal-ring semimetals (VNRs) and Hop…
Plasmon modes in tilted three-dimensional nodal-ring semimetals. I. -symmetric nodal ring and its gapped cousin

We study collective charge excitations in three-dimensional -symmetric nodal-ring semimetals (PTNRs) and their gapped counterparts (GNRs) in the presence of band tilt…
Direction-dependent magnetoelectric conductivity from dipolar topological semimetals
Firdous Haidar, Ipsita Mandal
We compute the linear magnetoelectric conductivity of a two-band vortex nodal-ring (VNR) semimetal and a three-band Hopf semimetal (HSM) within the semiclassical Boltzmann formalis…
Floquet scattering and Fano resonances in nodal-ring and multi-Weyl semimetals: Role of propagating and evanescent modes
Sandip Bera, Ipsita Mandal
We develop a comprehensive Floquet scattering theory for quantum transport in periodically driven nodal-ring semimetals (NRSs) and multi-Weyl semimetals (mWSMs), extending our earl…
Magnetoconductivity of two-dimensional Dirac cones and gapped nodal-rings under impurity-potentials in the ultraquantum limit

We investigate the dc magnetoconductivity of two-dimensional Dirac cones and gapped nodal rings (GNRs) subjected to a perpendicular magnetic field, which quantises the electronic s…
Linear response from tilted Dirac cones under strain-induced pseudomagnetic fields
Sanskar Sharma, Ipsita Mandal
We investigate the transport signatures of pseudo-Landau levels (PLLs) in two-dimensional anisotropic Dirac systems with tilted cones, whose effective bandstructure results from st…
Interplay of strain-induced axial gauge fields and intrinsic band-topology in the magnetoelectric conductivity of gapped nodal rings
Firdous Haidar, Muhammed Jaffar A., Ipsita Mandal
We compute the magnetoelectric conductivity of a semimetal hosting an ideal gapped nodal ring (GNR) in three distinct planar-Hall configurations, in the simultaneous presence of an…
Puiseux series about exceptional singularities dictated by symmetry-allowed Hessenberg forms of perturbation matrices
Ipsita Mandal
We develop a systematic framework for determining the nature of exceptional points of order (EPs) in non-Hermitian (NH) systems, represented by complex square matr…
Unconventional magnetoelectric conductivity and electrochemical response from dipole-like sources of Berry curvature
Ipsita Mandal
We investigate the longitudinal magnetoelectric conductivity and nonlinear electrochemical response (ECR) of three-dimensional nodal-ring semimetals, including vortex nodal-rings (…
