Weyl semimetals are a new member of the topological materials family, featuring a pair of
singly degenerate Weyl cones with linear dispersion around the nodes in the bulk, and …

Our sense of time is far from constant. For instance, time flies when we are having fun, and it
slows to a trickle when we are bored. Midbrain dopamine neurons have been implicated in …

Topological crystalline insulators are materials in which the crystalline symmetry leads to
topologically protected surface states with a chiral spin texture, rendering them potential …

A long-standing issue in topological insulator research has been to find a bulk single crystal
material that provides a high-quality platform for characterizing topological surface states …

The tunability of topological surface states and controllable opening of the Dirac gap are of
fundamental and practical interest in the field of topological materials. In the newly …

The topological crystalline insulator SnTe has been grown epitaxially on a Bi 2 Te 3 buffer
layer by molecular beam epitaxy. In a 30-nm-thick SnTe film, p-and n-type carriers are found …

In the recently discovered topological crystalline insulators SnTe and Pb 1− x Sn x (Te, Se),
crystal symmetry and electronic topology intertwine to create topological surface states with …

The newly discovered topological crystalline insulators feature a complex band structure
involving multiple Dirac cones,,,,,, and are potentially highly tunable by external electric field …

The physics related to Berry curvature is now a central research topic in condensed matter
physics. The Berry curvature dipole (BCD) is a significant and intriguing condensed matter …

We present angle-resolved photoemission spectroscopy measurements of the surface states
