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…
Hong-Ou-Mandel interferometry for fractional excitations: Unified framework and dip width scaling
Aleksander Latyshev, Imen Taktak, Ipsita Mandal +1
Extending Hong--Ou--Mandel (HOM) interferometry to the fractional quantum Hall effect (FQHE) promises direct access to anyonic statistics, yet remains challenging: on-demand anyon…
Non-Fermi liquid behaviour of CDW instabilities in fractionally-filled moiré flatbands
Ipsita Mandal
Spin- and valley-polarized fractionally-filled moiré flatbands are known to host emergent Fermi-liquid phases, when analysed with the help of a dual description in terms of holes.…
Disentangling contributions to longitudinal magnetoconductivity for Kramers-Weyl nodes
Ipsita Mandal
We set out to compute the longitudinal magnetoconductivity for an isolated and isotropic Kramers-Weyl node (KWN), existing in chiral crystals, which forms an exotic cousin of the c…
Longitudinal magnetoconductivity in chiral multifold semimetals exemplified by pseudospin-1 nodal points
Ipsita Mandal
We embark on computing the longitudinal magnetoconductivity within the semiclassical Boltzmann formalism, where an isotropic triple-point semimetal (TSM) is subjected to collinear…
Effects of time-periodic drive in the linear response for planar-Hall set-ups with Weyl and multi-Weyl semimetals
Ipsita Mandal
We investigate the influence of a time-periodic drive on three-dimensional Weyl and multi-Weyl semimetals in planar-Hall/planar-thermal-Hall set-ups. The drive is modelled here by…
