We explore the stability of three-dimensional Weyl and Dirac semimetals subject to
quasiperiodic potentials. We present numerical evidence that the semimetal is stable for …

The Brillouin zone of the clean Weyl semimetal contains points at which the density of states
(DOS) vanishes. Previous work suggested that below a certain critical concentration of …

We analyze theoretically the conductivity of Weyl semimetals within the self-consistent Born
approximation (SCBA) in the full range of disorder strength, from weak to strong disorder. In …

In this work we address the physics of individual three-dimensional Weyl nodes subject to a
moderate concentration of disorder. Previous analysis indicates the presence of a quantum …

Existing theoretical works differ on whether three-dimensional Dirac and Weyl semimetals
are stable to a short-range-correlated random potential. Numerical evidence suggests the …

Despite extensive existing studies, a complete understanding of the role of disorder in
affecting the physical properties of two-dimensional Dirac fermionic systems remains a …

We present a functional renormalization-group approach to interacting topological Green's
function invariants with a focus on the nature of transitions. The method is applied to chiral …

The functional renormalization group (FRG) has been used widely to investigate phase
diagrams, in particular the one of the two-dimensional Hubbard model. So far, the study of …

Rejuvenation of hydrodynamic transport in solids provides a new window to study the
collective motion of electrons, where electrons behave like a viscous fluid akin to classical …

We study a non-Anderson disorder driven quantum phase transition in a semi-infinite Dirac
semimetal with a flat boundary. The conformally invariant boundary conditions, which …
