Semiclassical transport in two-dimensional Dirac materials with spatially variable tilt
Abolfath Hosseinzadeh, Seyed Akbar Jafari
We use Boltzmann theory to study the semi-classical dynamics of electrons in a two-dimensional (2D) tilted Dirac material in which the tilt varies in space. The spatial variation o…
Tilt induced vortical response and mixed anomaly in inhomogeneous Weyl matter
Saber Rostamzadeh, Sevval Tasdemir, Mustafa Sarisaman +2
We propose a non-dissipative transport effect and vortical response in Weyl semimetals in the presence of spatial inhomogeneities, namely a spatially varying tilt of the Weyl cones…
Undamped inter-valley paramagnons in doped graphene
S. A. Jafari, J. König
We predict the existence of an undamped collective spin excitation in doped graphene in the paramagnetic regime, referred to as paramagnons. Since the electrons and the holes invol…
Electron Currents from Gradual Heating in Tilted Dirac Cone Materials
A. Moradpouri, M. Torabian, S. A. Jafari
Materials hosting tilted Dirac/Weyl fermions provide an emergent spacetime structure for the solid state physics. They admit a geometric description in terms of an effective spacet…
Synthetic non-Abelian gauge fields and gravitomagnetic effects in tilted Dirac cone systems
Tohid Farajollahpour, S. A. Jafari
In planar tilted Dirac cone systems, the tilt parameter can be made space-dependent by either a perpendicular displacement field, or by chemical substitution in certain systems. We…
Fast nuclear spin relaxation rates in tilted cone Weyl semimetals: Redshift factors from Korringa relation
Azin Mohajerani, Zahra Faraei, S. A. Jafari
Spin lattice relaxation rate is investigated for 3D tilted cone Weyl semimetals (TCWSMs). The nuclear spin relaxation rate is presented as a function of temperature and tilt parame…
