Light engineering of correlated states in topological materials provides a new avenue of
achieving exotic topological phases inaccessible by conventional tuning methods. Here we …

The classification scheme of electronic phases uses two prominent paradigms: correlations
and topology. Electron correlations give rise to superconductivity and charge density waves …

Topological semimetals are a new class of metallic materials, which exist at band fillings that
ordinarily correspond to insulators or compensated accidental semimetals with zero …

Luttinger's theorem connects a basic microscopic property of a given metallic crystalline
material, the number of electrons per unit cell, to the volume, enclosed by its Fermi surface …

Axion insulators are 3D magnetic topological insulators supporting hinge states and
quantized magnetoelectric effects, recently proposed for detecting dark-matter axionic …

In recent theoretical and experimental investigations, researchers have linked the low-
energy field theory of a Weyl semimetal gapped with a charge-density wave (CDW) to high …

The spacetime light cone is central to the definition of causality in the theory of relativity.
Recently, links between relativistic and condensed matter physics have been uncovered …

It has recently been demonstrated that it is possible to open a gap in a magnetic Weyl
semimetal, while preserving the chiral anomaly along with the charge conservation and …

Due to the chiral anomaly, Weyl semimetals can exhibit a signature topological
magnetoelectric response known as an axion term which is determined by the microscopic …

We describe a crystalline topological insulator (TI) phase of matter that exhibits spontaneous
polarization in arbitrary dimensions. The bulk polarization response is constructed by …
