Polymorphic 2D materials allow structural and electronic phase engineering, which can be
used to realize energy-efficient, cost-effective, and scalable device applications. The phase …

Vortices are the hallmarks of hydrodynamic flow. Strongly interacting electrons in ultrapure
conductors can display signatures of hydrodynamic behaviour, including negative non-local …

In recent years, transition metal dichalcogenides (TMDs) have garnered great interest as
topological materials. In particular, monolayers of centrosymmetric β-phase TMDs have …

Weyl semimetal is a new quantum state of matter,,,,,,,,,,, hosting the condensed matter
physics counterpart of the relativistic Weyl fermions originally introduced in high-energy …

Magnetoresistance (MR) is a characteristic that the resistance of a substance changes with
the external magnetic field, reflecting various physical origins and microstructures of the …

The nonlinear Hall effect (NLHE), the phenomenon in which a transverse voltage can be
produced without a magnetic field, provides a potential alternative for rectification or …

We use ultrahigh resolution, tunable, vacuum ultraviolet laser angle-resolved photoemission
spectroscopy (ARPES) to study the electronic properties of WTe 2, a material that was …

A Weyl semimetal is a new state of matter that hosts Weyl fermions as emergent
quasiparticles. The Weyl fermions correspond to isolated points of bulk band degeneracy …

We report a combined experimental and theoretical study of the candidate type-II Weyl
semimetal MoTe 2. Using laser-based angle-resolved photoemission, we resolve multiple …

In topological quantum materials,, the conduction and valence bands are connected at
points or along lines in the momentum space. A number of studies have demonstrated that …
