We review the physics of pair-density wave (PDW) superconductors. We begin with a
macroscopic description that emphasizes order induced by PDW states, such as charge …

The discovery of the quantum spin Hall effect and topological insulators more than a decade
ago has revolutionized modern condensed matter physics. Today, the field of topological …

By using first-principles calculations and ak· p model analysis, we propose that the three-
dimensional topological nodal line semimetal state can be realized in the CaP 3 family of …

A pair density wave (PDW) is a superconductor whose order parameter is a periodic function
of space, without an accompanying spatially uniform component. Since PDWs are not the …

We study the effects of short-range interactions on a generalized three-dimensional Weyl
semimetal, where the band touching points act as the (anti) monopoles of Abelian Berry …

The interplay between electronic correlations and topological protection may offer a rich
avenue for discovering emergent quantum phenomena in condensed matter. However …

We study the intrinsic fully gapped odd-parity superconducting order in doped nodal-loop
materials with a torus-shaped Fermi surface. We show that the mirror symmetry, which …

There is an immense effort in search for various types of Weyl semimetals, of which the most
fundamental phase consists of the minimal number of ie two Weyl points, but is hard to …

According to a widely held paradigm, a pair of Weyl points with opposite chirality mutually
annihilate when brought together. In contrast, we show that such a process is strictly …

We study surface superconductivity involving the “drumhead” surface states of (doped) Weyl
loop materials. The leading weak-coupling instability in the bulk is toward a chiral …
