Quantum Hall effect and optical magneto-conductivity of two-dimensional topological nodal-line semimetals
Shahin Barati, Hamid Rahimpoor, Saeed H. Abedinpour
We investigate a gapped two-dimensional nodal-line semimetal subjected to a perpendicular magnetic field. We identify an unusual pattern for Landau levels, where the energy of Land…
Magneto-thermoelectricty of anisotropic two-dimensional materials
Maryam Nezafat, Shahin Barati, Saeed H. Abedinpour
We use semiclassical Boltzmann transport theory to analytically study the electronic contribution to the linear thermoelectric response of anisotropic two-dimensional materials sub…
Collective excitations and screening in two-dimensional tilted nodal-line semimetals
Hamid Rahimpoor, Saeed H. Abedinpour
Topological nodal-line semimetals are characterized by symmetry-protected one-dimensional band-touching lines or loops, which give rise to their peculiar Fermi surfaces at low ener…
Many-body correction to the intrinsic anomalous and spin Hall conductivities
Moslem Mir, Saeed H. Abedinpour
Broken Galilean invariance in a spin-orbit coupled system can amplify many-body effects on its different responses. We study the anomalous Hall and spin Hall conductivities of a ma…
Thermoelectric response of nodal-line semimetals: probe of the Fermi surface topology
Shahin Barati, Saeed H. Abedinpour
We investigate the low-temperature thermoelectric properties of three-dimensional nodal-line semimetals within the semiclassical Boltzmann formalism. Considering short-range intera…
Dynamical density response and collective modes of topological insulator ultra-thin films
Moslem Mir, Saeed H. Abedinpour
We analytically calculate the intra- and inter-surface dynamical density-density linear responses of ultra-thin topological insulator films with finite tunneling between their top…
Relaxation times and charge conductivity of silicene
Azadeh Mazloom, Fariborz Parhizgar, Saeed H. Abedinpour +1
We investigate the transport and single particle relaxation times of silicene in the presence of neutral and charged impurities. The static charge conductivity is studied using the…
Anisotropic conductivity in magnetic topological insulators
A. Sabzalipour, J. Abouie, S. H. Abedinpour
We study the surface conductivity of a three dimensional topological insulator doped with magnetic impurities. The spin-momentum locking of surface electrons makes their scattering…
Boltzmann conductivity of ferromagnetic graphene with magnetic impurities
B. Zare Rameshti, A. G. Moghaddam, S. H. Abedinpour +2
We investigate the electrical conductivity of spin-polarized graphene in the presence of short-ranged magnetic scatterers within the relaxation time approximation and the semi-clas…
Drude weight, plasmon dispersion, and a.c. conductivity in doped graphene sheets
Saeed H. Abedinpour, G. Vignale, A. Principi +3
We demonstrate that the plasmon frequency and Drude weight of the electron liquid in a doped graphene sheet are strongly renormalized by electron-electron interactions even in the…
Theory of the Pseudospin Resonance in Semiconductor Bilayers
Saeed H. Abedinpour, Marco Polini, A. H. MacDonald +3
The pseudospin degree of freedom in a semiconductor bilayer gives rise to a collective mode analogous to the ferromagnetic resonance mode of a ferromagnet. We present a theory of t…
Analytic theory of pair distribution functions in symmetric electron-electron and electron-hole bilayers
S. H. Abedinpour, R. Asgari, M. Polini +1
We present a self-consistent analytic theory of the intra-layer and inter-layer pair correlation functions in electron-electron and electron-hole fluid bilayer systems. Our approac…
