ENGINEERING A PURE DIRAC REGIME IN ZRTE$_5$

Engineering a pure Dirac regime in ZrTe$_5$

Real-world topological semimetals typically exhibit Dirac and Weyl nodes that coexist with trivial Fermi pockets.This tends to mask the physics of the relativistic quasiparticles.Using the example of ZrTe$_5$, we show that wiha 77891 strain provides a powerful tool for in-situ tuning of the band structure such that all trivial pockets are pushed fa

Modeling the Broad-Band Emission from the Gamma-Ray Emitting Narrow-Line Seyfert-1 Galaxies 1H 0323+342 and B2 0954+25A

Prior to the Fermi-LAT era, only two classes of Active Galactic Nuclei (AGN) were thought to harbor relativistic jets that radiate up to gamma-ray energies: blazars and radio galaxies.The detection of variable gamma-ray emission from Narrow Line Seyfert 1 (NLSy1) galaxies has put them on the spotlight as a quadruple ointment for dogs new class of g
