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 …

Topological insulators and topological semimetals are both new classes of quantum
materials, which are characterized by surface states induced by the topology of the bulk …

Noncentrosymmetric metals are anticipated to exhibit a dc photocurrent in the nonlinear
optical response caused by the Berry curvature dipole in momentum space. Weyl …

Recently, the existence of massless chiral (Weyl) fermions has been postulated in a class of
semi-metals with a non-trivial energy dispersion. These materials are now commonly …

In the ferromagnetic (FM) Weyl semimetal CeAlSi both space-inversion and time-reversal
symmetries are broken. Our quantum oscillation (QO) data indicate that the FM ordering …

Topological transition metal dichalcogenides (TMDCs) have attracted much attention due to
their potential applications in spintronics and quantum computations. In this work, the …

The coexistence of superconductivity and topology holds the potential to realize exotic
quantum states of matter. Here, we report superconductivity induced by high pressure in …

The TaAs family (NbAs, TaAs, NbP, TaP) are kinds of Weyl semimetals with lots of novel
properties, thus attracting considerable attention in recent years. Here, we systematically …

Tunable symmetry breaking plays a crucial role for the manipulation of topological phases of
quantum matter. Here, through combined high-pressure magnetotransport measurements …

We review our recent works on the quantum transport, mainly in topological semimetals and
also in topological insulators, organized according to the strength of the magnetic field. At …
