Query: Dynamical signatures of point-gap Weyl semimetal   We demonstrate a few unique dynamical properties of point-gap Weyl semimetal,
an intrinsic non-Hermitian topological phase in three dimensions. We consider a
concrete model where a pair of Weyl points reside on the imaginary axis of the
complex energy plane, opening up a point gap characterized by a topological
invariant, the three-winding number $W_3$. This gives rise to surface spectra
and dynamical responses that differ fundamentally from those in Hermitian Weyl
semimetals. First, we predict a time-dependent current flowing along the
magnetic field in the absence of an electric field, in sharp contrast to the
current driven by the chiral anomaly, which requires both electric and magnetic
fields. Second, we reveal a novel type of boundary-skin mode in the wire
geometry which becomes localized at two corners of the wire cross section. We
explain its origin and show its experimental signatures in wave-packet
dynamics.
