Disorder in Weyl semimetals and superconductors is surprisingly subtle, attracting attention
and competing theories in recent years. In this brief review, we discuss the current …

The holographic duality allows to construct and study models of strongly coupled quantum
matter via dual gravitational theories. In general such models are characterized by the …

We highlight a general theory to engineer arbitrary Hermitian tight-binding lattice models in
electrical LC circuits, where the lattice sites are replaced by the electrical nodes, connected …

Weyl semimetals are arguably the most paradigmatic form of a gapless topological phase.
While the stability of Weyl nodes, as quantified by their topological charge, has been …

We study the effect of disorder in systems having a nontrivial Euler class. As these recently
proposed multigap topological phases come about by braiding non-Abelian charged band …

We investigate topological Cooper pairing, including gapless Weyl and fully gapped class
DIII superconductivity, in a three-dimensional doped Luttinger semimetal. The latter …

Three-dimensional higher-order topological semimetals in crystalline systems exhibit higher-
order Fermi arcs on one-dimensional hinges, challenging the conventional bulk-boundary …

Changes in the number of Weyl nodes in Weyl semimetals occur through merging
processes, usually involving a pair of oppositely charged nodes. More complicated …

We show that Weyl Fermi arcs are generically accompanied by a divergence of the surface
Berry curvature scaling as 1/k 2, where k is the distance to a hot line in the surface Brillouin …

We construct the effective field theory for time-reversal symmetry-breaking multi-Weyl
semimetals (MWSMs), composed of a single pair of Weyl nodes of (anti) monopole charge n …
