Nonthermal acceleration radiation of atoms near a black hole in presence of dark energy
Syed Masood A. S. Bukhari, Imtiyaz Ahmad Bhat, Chenni Xu +1
We investigate how dark energy affects atom-field interaction. To this end, we consider acceleration radiation of a freely falling atom close to a Schwarzschild black hole (BH) in…

Black hole mirages: electron lensing and Berry curvature effects in inhomogeneously tilted Weyl semimetals
Andreas Haller, Suraj Hegde, Chen Xu +3
We study electronic transport in Weyl semimetals with spatially varying nodal tilt profiles. We find that the flow of electrons can be guided precisely by judiciously chosen tilt p…
