Linear response of tilted anisotropic two-dimensional Dirac cones
Ipsita Mandal
We investigate the behaviour of the linear-response coefficients, when in-plane electric field () or/and temperature gradient () is/are applied on…
Chiral anomaly and internode scatterings in multifold semimetals
Ipsita Mandal
In our quest to unravel the topological properties of nodal points in three-dimensional semimetals, one hallmark property which warrants our attention is the \textit{chiral anomaly…
Characterizing topological pumping of charges in exactly solvable Rice-Mele chains of the non-Hermitian variety
Ipsita Mandal
We address the nature of the Thouless charge-pumping for a non-Hermitian (NH) generalization of the one-dimensional (1d) Rice-Mele model, considering a variety which allows closed-…
Anisotropic conductivity for the type-I and type-II phases of Weyl/multi-Weyl semimetals in planar Hall set-ups
Ipsita Mandal
We compute the non-Drude part of the conductivity tensor in planar Hall set-ups, for tilted Weyl and multi-Weyl semimetals, considering both the type-I and type-II phases. We do so…
Signatures of topology in generic transport measurements for Rarita-Schwinger-Weyl semimetals
Ipsita Mandal, Shreya Saha, Rahul Ghosh
We investigate how the signatures of the topological properties of the bandstructures for nodal-point semimetals are embedded in the response coefficients, arising in two distinct…
Linear response in planar Hall and thermal Hall setups for Rarita-Schwinger-Weyl semimetals
Rahul Ghosh, Firdous Haidar, Ipsita Mandal
We investigate the nature of the linear-response tensors in planar Hall and planar thermal Hall setups, where we subject a Rarita-Schwinger-Weyl (RSW) semimetal to the combined inf…
Induction of non-Fermi liquids by critical cavity photons at the onset of superradiance
Ipsita Mandal
We investigate the emergence of a non-Fermi liquid (NFL) at a putative quantum critical point signalling the onset of superradiance, in a set-up involving cavity quantum electrodyn…
Nature of Andreev bound states in Josephson junctions of triple-point semimetals
Ipsita Mandal
We study superconductor-barrier-superconductor (S-B-S) Josephson junctions constructed out of two-dimensional and three-dimensional triple-point semimetals, which feature a threefo…
Electric, thermal, and thermoelectric magnetoconductivity for Weyl/multi-Weyl semimetals in planar Hall set-ups induced by the combined effects of topology and strain
Leonardo Medel, Rahul Ghosh, Alberto Martín-Ruiz +1
We continue our investigation of the response tensors in planar Hall (or planar thermal Hall) configurations where a three-dimensional Weyl/multi-Weyl semimetal is subjected to the…
Transport properties in non-Fermi liquid phases of nodal-point semimetals
Ipsita Mandal, Hermann Freire
In this review, we survey the current progress in computing transport properties in semimetals which harbour non-Fermi liquid phases. We first discuss the widely-used Kubo formalis…
Stable non-Fermi liquid fixed point at the onset of incommensurate charge density wave order
Ipsita Mandal
We consider the emergence of a non-Fermi liquid fixed point in a two-dimensional metal, at the onset of a quantum phase transition from a Fermi liquid state to an incommensurate ch…
Direction-dependent conductivity in planar Hall set-ups with tilted Weyl/multi-Weyl semimetals
Rahul Ghosh, Ipsita Mandal
We compute the magnetoelectric conductivity tensors in planar Hall set-ups, which are built with tilted Weyl semimetals (WSMs) and multi-Weyl semimetals (mWSMs), considering all po…
Identifying gap-closings in open non-Hermitian systems by Biorthogonal Polarization
Ipsita Mandal
We investigate gap-closings in one- and two-dimensional tight-binding models with two bands, containing non-Hermitian hopping terms, and open boundary conditions (OBCs) imposed alo…
Non-Hermitian generalizations of the Yao-Lee model augmented by SO(3)-symmetry-breaking terms
Ipsita Mandal
We investigate non-Hermitian versions of the Yao-Lee model, supplemented by various kinds of SO(3)-symmetry-breaking terms, preserving the solvability of the model. The parent mode…
Andreev bound states in Josephson junctions of semi-Dirac semimetals
Ipsita Mandal
We consider a Josephson junction built with the two-dimensional semi-Dirac semimetal, which features a hybrid of linear and quadratic dispersion around a nodal point. We model the…
