Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

A large non-saturating magnetoresistance has been observed in several nonmagnetic
topological Weyl semi-metals with high mobility of charge carriers at the Fermi energy …

The quantum Hall effect (QHE) is traditionally considered to be a purely two-dimensional
(2D) phenomenon. Recently, however, a three-dimensional (3D) version of the QHE was …

Thermoelectric effects are more sensitive and promising probes to topological properties of
emergent materials, but much less addressed compared to other physical properties. We …

An extremely large linear magnetoresistance (LMR) is a ubiquitous phenomenon emerging
from topological Dirac and Weyl semimetals. However, the connection between an LMR and …

We review our most recent research on quantum transport, organizing the review according
to the intensity of the magnetic field and focus mostly on topological semimetals and …

Classical electromagnetism is linear. However, fields can polarize the vacuum Dirac sea,
causing quantum nonlinear electromagnetic phenomena, eg, scattering and splitting of …

Recently layered compound TaNi Te 5 was proposed to be two-dimensional (2D)
topological semimetals. Here we report the detailed investigation on TaNi Te 5 single …

Topological optics is an emerging research area in which various topological and
geometrical ideas are being proposed to design and manipulate the behaviors of photons …

We observed quantum oscillations in thermoelectric and magnetic torque signals in
noncentrosymmetric superconductor PbTaSe 2. One oscillatory frequency stems from the …
