Topological insulators hold great promise for dissipationless transport devices due to the
robust gapless states inside the insulating bulk gap. So far, several generations of …

Two-dimensional van der Waals magnetic semiconductors display emergent chemical and
physical properties and hold promise for novel optical, electronic and magnetic “few-layers” …

We investigate the optical response induced by a dc current flowing in a nonmagnetic
material that lacks inversion symmetry. In this class of materials, the flowing current …

Dirac materials, which feature Dirac cones in the reciprocal space, have been one of the
hottest topics in condensed matter physics in the past decade. To date, 2D and 3D Dirac …

Recent experiments have established a type of nonsymmorphic symmetry-protected nodal
lines in the family of two-dimensional (2D) composition-tunable materials NbSi x Te 2. Here …

Condensed matter systems in low dimensions exhibit emergent physics that does not exist
in three dimensions. When electrons are confined to one dimension (1D), some significant …

Glide-mirror symmetry in nonsymmorphic crystals can foster the emergence of novel
hourglass nodal loop states. Here, we present spectroscopic signatures from angle-resolved …

Spin qubits in semiconductor quantum dots represent a prominent family of solid-state qubits
in the effort to build a quantum computer. They are formed when electrons or holes are …

The ternary van der Waals material Nb2Si x–1Te4 demonstrates many interesting properties
as the content of Si is changed, ranging from metallic Nb3SiTe6 (x= 5/3) to narrow-gap …

Recent experiments have demonstrated interesting physics in a family of two-dimensional
composition-tunable materials Nb 2 n+ 1 Si n Te 4 n+ 2. Here we show that, owing to their …
